How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes in some cases), then run the installer (on Windows) or just copy over /Applications/Aixcoin-Qt (on macOS) or aixcoind/aixcoin-qt (on Linux).

Upgrading directly from a version of Aixcoin Core that has reached its EOL is possible, but it might take some time if the data directory needs to be migrated. Old wallet versions of Aixcoin Core are generally supported.

Compatibility

Aixcoin Core is supported and tested on operating systems using the Linux Kernel 3.17+, macOS 13+, and Windows 10+. Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Aixcoin Core on unsupported systems.

Aixcoin Core 30.0

Fri, 10 Oct 2025 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

30.0 Release Notes

Aixcoin Core version v30.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-30.0/

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

With the release of this new major version, versions 27.x and older are at “End of Life” and will no longer receive updates.

In accordance with the security policy, we will in two weeks disclose:

Medium and high severity vulnerabilities fixed in 28.0. There are none of these.
Low severity vulnerabilities fixed in 30.0. There are 5 of these.

How to Upgrade

Compatibility

Notable changes

Policy

The maximum number of potentially executed legacy signature operations in a single standard transaction is now limited to 2500. Signature operations in all previous output scripts, in all input scripts, as well as all P2SH redeem scripts (if there are any) are counted toward the limit. The new limit is assumed to not affect any known typically formed standard transactions. The change was done to prepare for a possible BIP54 deployment in the future. (#32521)
-datacarriersize is increased to 100,000 by default, which effectively uncaps the limit (as the maximum transaction size limit will be hit first). It can be overridden with -datacarriersize=83 to revert to the limit enforced in previous versions. (#32406)
Multiple data carrier (OP_RETURN) outputs in a transaction are now permitted for relay and mining. The -datacarriersize limit applies to the aggregate size of the scriptPubKeys across all such outputs in a transaction, not including the scriptPubKey size itself. (#32406)
The minimum block feerate (-blockmintxfee) has been changed to 0.001 satoshi per vB. It can still be changed using the configuration option. This option can be used by miners to set a minimum feerate on packages added to block templates. (#33106)
The default minimum relay feerate (-minrelaytxfee) and incremental relay feerate (-incrementalrelayfee) have been changed to 0.1 satoshis per vB. They can still be changed using their respective configuration options, but it is recommended to change both together if you decide to do so. (#33106)

Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume.

Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; -mintxfee must be changed before attempting to create transactions with lower feerates using the wallet. (#33106)

P2P and network changes

Opportunistic 1-parent-1-child package relay has been improved to handle situations when the child already has unconfirmed parent(s) in the mempool. This means that 1p1c packages can be accepted and propagate, even if they are connected to broader topologies: multi-parent-1-child (where only 1 parent requires fee-bumping), grandparent-parent-child (where only parent requires fee-bumping) etc. (#31385)
The transaction orphanage, which holds transactions with missing inputs temporarily while the node attempts to fetch its parents, now has improved Denial of Service protections. Previously, it enforced a maximum number of unique transactions (default 100, configurable using -maxorphantx). Now, its limits are as follows: the number of entries (unique by wtxid and peer), plus each unique transaction’s input count divided by 10, must not exceed 3,000. The total weight of unique transactions must not exceed 404,000 Wu multiplied by the number of peers. (#31829)
The -maxorphantx option no longer has any effect, since the orphanage no longer limits the number of unique transactions. Users should remove this configuration option if they were using it, as the setting will cause an error in future versions when it is no longer recognized. (#31829)

New `aixcoin` command

A new aixcoin command line tool has been added to make features more discoverable and convenient to use. The aixcoin tool just calls other executables and does not implement any functionality on its own. Specifically aixcoin node is a synonym for aixcoind, aixcoin gui is a synonym for aixcoin-qt, and aixcoin rpc is a synonym for aixcoin-cli -named. Other commands and options can be listed with aixcoin help. The new aixcoin command is an alternative to calling other commands directly, but it doesn’t replace them, and there are no plans to deprecate existing commands. (#31375)

External Signing

Support for external signing on Windows has been re-enabled. (#29868)

IPC Mining Interface

The new aixcoin command does support one new feature: an (experimental) IPC Mining Interface that allows the node to work with Stratum v2 or other mining client software, see (#31098). When the node is started with aixcoin -m node -ipcbind=unix it will listen on a unix socket for IPC client connections, allowing clients to request block templates and submit mined blocks. The -m option launches a new internal binary (aixcoin-node instead of aixcoind) and is currently required but will become optional in the future (with #33229).
IPC connectivity introduces new dependencies (see multiprocess.md), which can be turned off with the -DENABLE_IPC=OFF build option if you do not intend to use IPC. (#31802)

Install changes

The test_aixcoin executable is now installed in libexec/ instead of bin/. It can still be executed directly, or accessed through the new aixcoin command as aixcoin test. The libexec/ directory also contains new aixcoin-node and aixcoin-gui binaries which support IPC features and are called through the aixcoin tool. In source builds only, test_aixcoin-qt, bench_aixcoin, and aixcoin-chainstate are also now installed to libexec/ instead of bin/ and can be accessed through the new aixcoin command. See aixcoin help output for details. (#31679)
On Windows, the installer no longer adds a “(64-bit)” suffix to entries in the Start Menu (#32132), and it now automatically removes obsolete artifacts during upgrades (#33422).

Indexes

The implementation of coinstatsindex was changed to prevent an overflow bug that could already be observed on the default Signet. The new version of the index will need to be synced from scratch when starting the upgraded node for the first time.

The new version is stored in /indexes/coinstatsindex/ in contrast to the old version which was stored at /indexes/coinstats/. The old version of the index is not deleted by the upgraded node in case the user chooses to downgrade their node in the future. If the user does not plan to downgrade it is safe for them to remove /indexes/coinstats/ from their datadir. A future release of Aixcoin Core may remove the old version of the index automatically. (#30469)

Logging

Unconditional logging to disk is now rate limited by giving each source location a quota of 1MiB per hour. Unconditional logging is any logging with a log level higher than debug, that is info, warning, and error. All logs will be prefixed with [*] if there is at least one source location that is currently being suppressed. (#32604)
When -logsourcelocations is enabled, the log output now contains the entire function signature instead of just the function name. (#32604)

Updated RPCs

The -paytxfee startup option and the settxfee RPC are now deprecated and will be removed in Aixcoin Core 31.0. They allowed the user to set a static fee rate for wallet transactions, which could potentially lead to overpaying or underpaying. Users should instead rely on fee estimation or specify a fee rate per transaction using the fee_rate argument in RPCs such as fundrawtransaction, sendtoaddress, send, sendall, and sendmany. (#31278)
Any RPC in which one of the parameters is a descriptor will throw an error if the provided descriptor contains a whitespace at the beginning or the end of the public key within a fragment - e.g. pk( KEY) or pk(KEY ). (#31603)
The submitpackage RPC, which allows submissions of child-with-parents packages, no longer requires that all unconfirmed parents be present. The package may contain other in-mempool ancestors as well. (#31385)
The waitfornewblock RPC now takes an optional current_tip argument. It is also no longer hidden. (#30635)
The waitforblock and waitforblockheight RPCs are no longer hidden. (#30635)
The psbtbumpfee and bumpfee RPCs allow a replacement under fullrbf and no longer require BIP-125 signalling. (#31953)
Transaction Script validation errors used to return the reason for the error prefixed by either mandatory-script-verify-flag-failed if it was a consensus error, or non-mandatory-script-verify-flag (without “-failed”) if it was a standardness error. This has been changed to block-script-verify-flag-failed and mempool-script-verify-flag-failed for all block and mempool errors respectively. (#33183)
The getmininginfo RPC now returns “blockmintxfee” result specifying the value of -blockmintxfee configuration. (#33189)
The getmempoolinfo RPC now returns an additional “permitbaremultisig” and “maxdatacarriersize” field, reflecting the -permitbaremultisig and -datacarriersize config values. (#29954)

Changes to wallet-related RPCs can be found in the Wallet section below.

New RPCs

A new REST API endpoint (/rest/spenttxouts/BLOCKHASH) has been introduced for efficiently fetching spent transaction outputs using the block’s undo data (#32540).

Build System

Updated settings

The -maxmempool and -dbcache startup parameters are now capped on 32-bit systems to 500MB and 1GiB respectively. (#32530)
The -natpmp option is now set to 1 by default. This means nodes with -listen enabled (the default) but running behind a firewall, such as a local network router, will be reachable if the firewall/router supports any of the PCP or NAT-PMP protocols. (#33004)
The -upnp setting has now been fully removed. Use -natpmp instead. (#32500)
Previously, -proxy specified the proxy for all networks (except I2P which uses -i2psam) and only the Tor proxy could have been specified separately via -onion. Now, the syntax of -proxy has been extended and it is possible to specify separately the proxy for IPv4, IPv6, Tor and CJDNS by appending = followed by the network name, for example -proxy=127.0.0.1:5555=ipv6 configures a proxy only for IPv6. The -proxy option can be used multiple times to define different proxies for different networks, such as -proxy=127.0.0.1:4444=ipv4 -proxy=10.0.0.1:6666=ipv6. Later settings override earlier ones for the same network; this can be used to remove an earlier all-networks proxy and use direct connections only for a given network, for example -proxy=127.0.0.1:5555 -proxy=0=cjdns. (#32425)
The -blockmaxweight startup option has been updated to be debug-only. It is still available to users, but now hidden from the default -help text and shown only in -help-debug (#32654).

Changes to GUI or wallet related settings can be found in the GUI or Wallet section below.

Wallet

BDB legacy wallets can no longer be created or loaded. They can be migrated to the new descriptor wallet format. Refer to the migratewallet RPC for more details.
The legacy wallet removal drops redundant options in the aixcoin-wallet tool, such as -withinternalbdb, -legacy, and -descriptors. Moreover, the legacy-only RPCs addmultisigaddress, dumpprivkey, dumpwallet, importaddress, importmulti, importprivkey, importpubkey, importwallet, newkeypool, sethdseed, and upgradewallet, are removed. (#32944, #28710, #32438, #31250)
Support has been added for spending TRUC transactions received by the wallet, as well as creating TRUC transactions. The wallet ensures that TRUC policy rules are being met. The wallet will throw an error if the user is trying to spend TRUC utxos with utxos of other versions. Additionally, the wallet will treat unconfirmed TRUC sibling transactions as mempool conflicts. The wallet will also ensure that transactions spending TRUC utxos meet the required size restrictions. (#32896)
Since descriptor wallets do not allow mixing watchonly and non-watchonly descriptors, the include_watchonly option (and its variants in naming) are removed from all RPCs that had it. (#32618)
The iswatchonly field is removed from any RPCs that returned it. (#32618)
unloadwallet - Return RPC_INVALID_PARAMETER when both the RPC wallet endpoint and wallet_name parameters are unspecified. Previously the RPC failed with a JSON parsing error. (#32845)
getdescriptoractivity - Mark blockhashes and scanobjects arguments as required, so the user receives a clear help message when either is missing. As in unloadwallet, previously the RPC failed with a JSON parsing error. (#32845)
getwalletinfo - Removes the fields balance, immature_balance and unconfirmed_balance. (#32721)
getunconfirmedbalance - Removes this RPC command. You can query the getbalances RPC and inspect the "mine" "untrusted_pending" entry within the JSON response. (#32721)
The following RPCs now contain a version parameter that allows the user to create transactions of any standard version number (1-3):
- createrawtransaction
- createpsbt
- send
- sendall
- walletcreatefundedpsbt (#32896)

GUI changes

The GUI has been migrated from Qt 5 to Qt 6. On Windows, dark mode is now supported. On macOS, the Metal backend is now used. (#30997)
A transaction’s fee bump is allowed under fullrbf and no longer requires BIP-125 signalling. (#31953)
Custom column widths in the Transactions tab are reset as a side-effect of legacy wallet removal. (#32459)

Low-level changes

Logs now include which peer sent us a header. Additionally there are fewer redundant header log messages. A side-effect of this change is that for some untypical cases new headers aren’t logged anymore, e.g. a direct BLOCK message with a previously unknown header and submitheader RPC. (#27826)

Mempool Policy

The maximum number of potentially executed legacy signature operations in a single standard transaction is now limited to 2500. Signature operations in all previous output scripts, in all input scripts, as well as all P2SH redeem scripts (if there are any) are counted toward the limit. The new limit is assumed to not affect any known typically formed standard transactions. The change was done to prepare for a possible BIP54 deployment in the future.
#32521 policy: make pathological transactions packed with legacy sigops non-standard
The minimum block feerate (-blockmintxfee) has been changed to 1 satoshi per kvB. It can still be changed using the configuration option.
The default minimum relay feerate (-minrelaytxfee) and incremental relay feerate (-incrementalrelayfee) have been changed to 100 satoshis per kvB. They can still be changed using their respective configuration options, but it is recommended to change both together if you decide to do so.
- Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume.
- Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; -mintxfee must be changed before attempting to create transactions with lower feerates using the wallet.

Unconditional logging is any logging with a log level higher than debug, that is info, warning, and error.

When -logsourcelocations is enabled, the log output now contains the entire function signature instead of just the function name. (#32604)

RPC

The dumptxoutset RPC now requires a type parameter to be specified. To maintain pre v29.0 behavior, use the latest parameter. Documenting this change was missed in the v29.0 release notes. (#30808)

Updated Settings

The -maxmempool and -dbcache startup parameters are now capped on 32-bit systems to 500MB and 1GiB respectively.
#32530 node: cap -maxmempool and -dbcache values for 32-bit

How to Upgrade

Compatibility

Notable changes

P2P and Network Changes

Support for UPnP was dropped. If you want to open a port automatically, consider using the -natpmp option instead, which uses PCP or NAT-PMP depending on router support. (#31130)
libnatpmp was replaced with a built-in implementation of PCP and NAT-PMP (still enabled using the -natpmp option). This supports automatic IPv4 port forwarding as well as IPv6 pinholing. (#30043)
When the -port configuration option is used, the default onion listening port will now be derived to be that port + 1 instead of being set to a fixed value (8334 on mainnet). This re-allows setups with multiple local nodes using different -port and not using -bind, which would lead to a startup failure in v28.0 due to a port collision. Note that a HiddenServicePort manually configured in torrc may need adjustment if used in connection with the -port option. For example, if you are using -port=5555 with a non-standard value and not using -bind=...=onion, previously Aixcoin Core would listen for incoming Tor connections on 127.0.0.1:8334. Now it would listen on 127.0.0.1:5556 (-port plus one). If you configured the hidden service manually in torrc now you have to change it from HiddenServicePort 8333 127.0.0.1:8334 to HiddenServicePort 8333 127.0.0.1:5556, or configure aixcoind with -bind=127.0.0.1:8334=onion to get the previous behavior. (#31223)
Upon receiving an orphan transaction (an unconfirmed transaction that spends unknown inputs), the node will attempt to download missing parents from all peers who announced the orphan. This change may increase bandwidth usage but make orphan-handling more reliable. (#31397)

Mempool Policy and Mining Changes

Ephemeral dust is a new concept that allows a single dust output in a transaction, provided the transaction is zero fee. In order to spend any unconfirmed outputs from this transaction, the spender must also spend this dust in addition to any other desired outputs. In other words, this type of transaction should be created in a transaction package where the dust is both created and spent simultaneously. (#30239)
Due to a bug, the default block reserved weight (4,000 WU) for fixed-size block header, transactions count, and coinbase transaction was reserved twice and could not be lowered. As a result the total reserved weight was always 8,000 WU, meaning that even when specifying a -blockmaxweight higher than the default (even to the max of 4,000,000 WU), the actual block size will never exceed 3,992,000 WU. The fix consolidates the reservation into a single place and introduces a new startup option, -blockreservedweight which specifies the reserved weight directly. The default value of -blockreservedweight is set to 8,000 WU to ensure backward compatibility for users who relied on the previous behavior of -blockmaxweight. The minimum value of -blockreservedweight is set to 2,000 WU. Users setting -blockreservedweight below the default should ensure that the total weight of their block header, transaction count, and coinbase transaction does not exceed the reduced value or they may risk mining an invalid block. (#31384)

Updated RPCs

The RPC testmempoolaccept response now includes a reject-details field in some cases, similar to the complete error messages returned by sendrawtransaction (#28121)
Duplicate blocks submitted with submitblock will now persist their block data even if it was previously pruned. If pruning is activated, the data will be pruned again eventually once the block file it is persisted in is selected for pruning. This is consistent with the behaviour of getblockfrompeer where the block is persisted as well even when pruning. (#31175)
getmininginfo now returns nBits and the current target in the target field. It also returns a next object which specifies the height, nBits, difficulty, and target for the next block. (#31583)
getblock and getblockheader now return the current target in the target field (#31583)
getblockchaininfo and getchainstates now return nBits and the current target in the target field (#31583)
the getblocktemplate RPC curtime (BIP22) and mintime (BIP23) fields now account for the timewarp fix proposed in BIP94 on all networks. This ensures that, in the event a timewarp fix softfork activates on mainnet, un-upgraded miners will not accidentally violate the timewarp rule. (#31376, #31600) As a reminder, it’s important that any software which uses the getblocktemplate RPC takes these values into account (either curtime or mintime is fine). Relying only on a clock can lead to invalid blocks under some circumstances, especially once a timewarp fix is deployed. (#31600)

New RPCs

getdescriptoractivity can be used to find all spend/receive activity relevant to a given set of descriptors within a set of specified blocks. This call can be used with scanblocks to lessen the need for additional indexing programs. (#30708)

Updated REST APIs

GET /rest/block/<BLOCK-HASH>.json and GET /rest/headers/<BLOCK-HASH>.json now return the current target in the target field

Updated Settings

The maximum allowed value for the -dbcache configuration option has been dropped due to recent UTXO set growth. Note that before this change, large -dbcache values were automatically reduced to 16 GiB (1 GiB on 32 bit systems). (#28358)
Handling of negated -noseednode, -nobind, -nowhitebind, -norpcbind, -norpcallowip, -norpcwhitelist, -notest, -noasmap, -norpcwallet, -noonlynet, and -noexternalip options has changed. Previously negating these options had various confusing and undocumented side effects. Now negating them just resets the settings and restores default behaviors, as if the options were not specified.
Starting with v28.0, the -mempoolfullrbf startup option was set to default to 1. With widespread adoption of this policy, users no longer benefit from disabling it, so the option has been removed, making full replace-by-fee the standard behavior. (#30592)
Setting -upnp will now log a warning and be interpreted as -natpmp. Consider using -natpmp directly instead. (#31130, #31916)
As a safety check, Aixcoin core will fail to start when -blockreservedweight init parameter value is lower than 2000 weight units. Aixcoin Core will also fail to start if the -blockmaxweight or -blockreservedweight init parameter exceeds consensus limit of 4,000,000 WU.
Passing -debug=0 or -debug=none now behaves like -nodebug: previously set debug categories will be cleared, but subsequent -debug options will still be applied.
The default for -rpcthreads has been changed from 4 to 16, and the default for -rpcworkqueue has been changed from 16 to 64. (#31215).

Build System

The build system has been migrated from Autotools to CMake:

The minimum required CMake version is 3.22.
In-source builds are not allowed. When using a subdirectory within the root source tree as a build directory, it is recommended that its name includes the substring “build”.
CMake variables may be used to configure the build system. Some defaults have changed. For example, you will now need to add -DWITH_ZMQ=ON to build with zmq and -DBUILD_GUI=ON to build aixcoin-qt. See Autotools to CMake Options Mapping for details.
For single-configuration generators, the default build configuration (CMAKE_BUILD_TYPE) is “RelWithDebInfo”. However, for the “Release” configuration, CMake defaults to the compiler optimization flag -O3, which has not been extensively tested with Aixcoin Core. Therefore, the build system replaces it with -O2.
By default, the built executables and libraries are located in the bin/ and lib/ subdirectories of the build directory.
The build system supports component‐based installation. The names of the installable components coincide with the build target names. For example:

cmake -B build
cmake --build build --target aixcoind
cmake --install build --component aixcoind

If any of the CPPFLAGS, CFLAGS, CXXFLAGS or LDFLAGS environment variables were used in your Autotools-based build process, you should instead use the corresponding CMake variables (APPEND_CPPFLAGS, APPEND_CFLAGS, APPEND_CXXFLAGS and APPEND_LDFLAGS). Alternatively, if you opt to use the dedicated CMAKE_<...>_FLAGS variables, you must ensure that the resulting compiler or linker invocations are as expected.

For more detailed guidance on configuring and using CMake, please refer to the official CMake documentation and CMake’s User Interaction Guide. Additionally, consult platform-specific doc/build-*.md build guides for instructions tailored to your operating system.

Low-Level Changes

Tools and Utilities

A new tool utxo_to_sqlite.py converts a compact-serialized UTXO snapshot (as created with the dumptxoutset RPC) to a SQLite3 database. Refer to the script’s --help output for more details. (#27432)

Tests

The BIP94 timewarp attack mitigation (designed for testnet4) is no longer active on the regtest network. (#31156)

Dependencies

MiniUPnPc and libnatpmp have been removed as dependencies (#31130, #30043).

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

28.3 Release Notes

Aixcoin Core version 28.3 is now available from:

How to Upgrade

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux Kernel 3.17+, macOS 11.0+, and Windows 7 and newer. Aixcoin Core should also work on most other UNIX-like systems but is not as frequently tested on them. It is not recommended to use Aixcoin Core on unsupported systems.

Notable changes

Mempool & Policy

The minimum block feerate (-blockmintxfee) has been changed to 1 satoshi per kvB. It can still be changed using the configuration option.

The default minimum relay feerate (-minrelaytxfee) and incremental relay feerate (-incrementalrelayfee) have been changed to 100 satoshis per kvB. They can still be changed using their respective configuration options, but it is recommended to change both together if you decide to do so.
- Other minimum feerates (e.g. the dust feerate, the minimum returned by the fee estimator, and all feerates used by the wallet) remain unchanged. The mempool minimum feerate still changes in response to high volume.
- Note that unless these lower defaults are widely adopted across the network, transactions created with lower fee rates are not guaranteed to propagate or confirm. The wallet feerates remain unchanged; -mintxfee must be changed before attempting to create transactions with lower feerates using the wallet.

When the -port configuration option is used, the default onion listening port will now be derived to be that port + 1 instead of being set to a fixed value (8334 on mainnet). This re-allows setups with multiple local nodes using different -port and not using -bind, which would lead to a startup failure in v28.0 due to a port collision.

Note that a HiddenServicePort manually configured in torrc may need adjustment if used in connection with the -port option. For example, if you are using -port=5555 with a non-standard value and not using -bind=...=onion, previously Aixcoin Core would listen for incoming Tor connections on 127.0.0.1:8334. Now it would listen on 127.0.0.1:5556 (-port plus one). If you configured the hidden service manually in torrc now you have to change it from HiddenServicePort 8333 127.0.0.1:8334 to HiddenServicePort 8333 127.0.0.1:5556, or configure aixcoind with -bind=127.0.0.1:8334=onion to get the previous behavior.

Aixcoin Core 28.0

Wed, 02 Oct 2024 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

28.0 Release Notes

Aixcoin Core version 28.0 is now available from:

How to Upgrade

codesign -s - aixcoin-cli aixcoin-qt aixcoin-tx aixcoin-util aixcoin-wallet aixcoind test_aixcoin

Compatibility

Notable changes

Testnet4/BIP94 support

Support for Testnet4 as specified in BIP94 has been added. The network can be selected with the -testnet4 option and the section header is also named [testnet4].

While the intention is to phase out support for Testnet3 in an upcoming version, support for it is still available via the known options in this release. (#29775)

Windows Data Directory

The default data directory on Windows has been moved from C:\Users\Username\AppData\Roaming\Aixcoin to C:\Users\Username\AppData\Local\Aixcoin. Aixcoin Core will check the existence of the old directory first and continue to use that directory for backwards compatibility if it is present. (#27064)

JSON-RPC 2.0 Support

The JSON-RPC server now recognizes JSON-RPC 2.0 requests and responds with strict adherence to the specification. See JSON-RPC-interface.md for details. (#27101)

JSON-RPC clients may need to be updated to be compatible with the JSON-RPC server. Please open an issue on GitHub if any compatibility issues are found.

libaixcoinconsensus Removal

The libaixcoin-consensus library was deprecated in 27.0 and is now completely removed. (#29648)

P2P and Network Changes

Previously if Aixcoin Core was listening for P2P connections, either using default settings or via bind=addr:port it would always also bind to 127.0.0.1:8334 to listen for Tor connections. It was not possible to switch this off, even if the node didn’t use Tor. This has been changed and now bind=addr:port results in binding on addr:port only. The default behavior of binding to 0.0.0.0:8333 and 127.0.0.1:8334 has not been changed.

If you are using a bind=... configuration without bind=...=onion and rely on the previous implied behavior to accept incoming Tor connections at 127.0.0.1:8334, you need to now make this explicit by using bind=... bind=127.0.0.1:8334=onion. (#22729)
Aixcoin Core will now fail to start up if any of its P2P binds fail, rather than the previous behaviour where it would only abort startup if all P2P binds had failed. (#22729)
UNIX domain sockets can now be used for proxy connections. Set -onion or -proxy to the local socket path with the prefix unix: (e.g. -onion=unix:/home/me/torsocket). (#27375)
UNIX socket paths are now accepted for -zmqpubrawblock and -zmqpubrawtx with the format -zmqpubrawtx=unix:/path/to/file (#27679)
Additional “in” and “out” flags have been added to -whitelist to control whether permissions apply to inbound connections and/or manual ones (default: inbound only). (#27114)
Transactions having a feerate that is too low will be opportunistically paired with their child transactions and submitted as a package, thus enabling the node to download 1-parent-1-child packages using the existing transaction relay protocol. Combined with other mempool policies, this change allows limited “package relay” when a parent transaction is below the mempool minimum feerate. Topologically Restricted Until Confirmation (TRUC) parents are additionally allowed to be below the minimum relay feerate (i.e., pay 0 fees). Use the submitpackage RPC to submit packages directly to the node. Warning: this P2P feature is limited (unlike the submitpackage interface, a child with multiple unconfirmed parents is not supported) and not yet reliable under adversarial conditions. (#28970)

Mempool Policy Changes

Transactions with version number set to 3 are now treated as standard on all networks (#29496), subject to opt-in Topologically Restricted Until Confirmation (TRUC) transaction policy as described in BIP 431. The policy includes limits on spending unconfirmed outputs (#28948), eviction of a previous descendant if a more incentive-compatible one is submitted (#29306), and a maximum transaction size of 10,000vB (#29873). These restrictions simplify the assessment of incentive compatibility of accepting or replacing TRUC transactions, thus ensuring any replacements are more profitable for the node and making fee-bumping more reliable.
Pay To Anchor (P2A) is a new standard witness output type for spending, a newly recognised output template. This allows for key-less anchor outputs, with compact spending conditions for additional efficiencies on top of an equivalent sh(OP_TRUE) output, in addition to the txid stability of the spending transaction. N.B. propagation of this output spending on the network will be limited until a sufficient number of nodes on the network adopt this upgrade. (#30352)
Limited package RBF is now enabled, where the proposed conflicting package would result in a connected component, aka cluster, of size 2 in the mempool. All clusters being conflicted against must be of size 2 or lower. (#28984)
The default value of the -mempoolfullrbf configuration option has been changed from 0 to 1, i.e. mempoolfullrbf=1. (#30493)

Updated RPCs

The dumptxoutset RPC now returns the UTXO set dump in a new and improved format. Correspondingly, the loadtxoutset RPC now expects this new format in the dumps it tries to load. Dumps with the old format are no longer supported and need to be recreated using the new format to be usable. (#29612)
AssumeUTXO mainnet parameters have been added for height 840,000. This means the loadtxoutset RPC can now be used on mainnet with the matching UTXO set from that height. (#28553)
The warnings field in getblockchaininfo, getmininginfo and getnetworkinfo now returns all the active node warnings as an array of strings, instead of a single warning. The current behaviour can be temporarily restored by running Aixcoin Core with the configuration option -deprecatedrpc=warnings. (#29845)
Previously when using the sendrawtransaction RPC and specifying outputs that are already in the UTXO set, an RPC error code of -27 with the message “Transaction already in block chain” was returned in response. The error message has been changed to “Transaction outputs already in utxo set” to more accurately describe the source of the issue. (#30212)
The default mode for the estimatesmartfee RPC has been updated from conservative to economical, which is expected to reduce over-estimation for many users, particularly if Replace-by-Fee is an option. For users that require high confidence in their fee estimates at the cost of potentially over-estimating, the conservative mode remains available. (#30275)
RPC scantxoutset now returns 2 new fields in the “unspents” JSON array: blockhash and confirmations. See the scantxoutset help for details. (#30515)
RPC submitpackage now allows 2 new arguments to be passed: maxfeerate and maxburnamount. See the subtmitpackage help for details. (#28950)

Changes to wallet-related RPCs can be found in the Wallet section below.

Updated REST APIs

Parameter validation for /rest/getutxos has been improved by rejecting truncated or overly large txids and malformed outpoint indices via raising an HTTP_BAD_REQUEST “Parse error”. These requests were previously handled silently. (#30482, #30444)

Build System

GCC 11.1 or later, or Clang 16.0 or later, are now required to compile Aixcoin Core. (#29091, #30263)
The minimum required glibc to run Aixcoin Core is now 2.31. This means that RHEL 8 and Ubuntu 18.04 (Bionic) are no-longer supported. (#29987)
--enable-lcov-branch-coverage has been removed, given incompatibilities between lcov version 1 & 2. LCOV_OPTS should be used to set any options instead. (#30192)

Updated Settings

When running with -alertnotify, an alert can now be raised multiple times instead of just once. Previously, it was only raised when unknown new consensus rules were activated. Its scope has now been increased to include all kernel warnings. Specifically, alerts will now also be raised when an invalid chain with a large amount of work has been detected. Additional warnings may be added in the future. (#30058)

Changes to GUI or wallet related settings can be found in the GUI or Wallet section below.

Wallet

The wallet now detects when wallet transactions conflict with the mempool. Mempool-conflicting transactions can be seen in the "mempoolconflicts" field of gettransaction. The inputs of mempool-conflicted transactions can now be respent without manually abandoning the transactions when the parent transaction is dropped from the mempool, which can cause wallet balances to appear higher. (#27307)
A new max_tx_weight option has been added to the RPCs fundrawtransaction, walletcreatefundedpsbt, and send. It specifies the maximum transaction weight. If the limit is exceeded during funding, the transaction will not be built. The default value is 4,000,000 WU. (#29523)
A new createwalletdescriptor RPC allows users to add new automatically generated descriptors to their wallet. This can be used to upgrade wallets created prior to the introduction of a new standard descriptor, such as taproot. (#29130)
A new RPC gethdkeys lists all of the BIP32 HD keys in use by all of the descriptors in the wallet. These keys can be used in conjunction with createwalletdescriptor to create and add single key descriptors to the wallet for a particular key that the wallet already knows. (#29130)
The sendall RPC can now spend unconfirmed change and will include additional fees as necessary for the resulting transaction to bump the unconfirmed transactions’ feerates to the specified feerate. (#28979)
In RPC bumpfee, if a fee_rate is specified, the feerate is no longer restricted to following the wallet’s incremental feerate of 5 sat/vb. The feerate must still be at least the sum of the original fee and the mempool’s incremental feerate. (#27969)

GUI Changes

The “Migrate Wallet” menu allows users to migrate any legacy wallet in their wallet directory, regardless of the wallets loaded. (gui#824)
The “Information” window now displays the maximum mempool size along with the mempool usage. (gui#825)

Low-level Changes

Tests

The BIP94 timewarp attack mitigation is now active on the regtest network. (#30681)
A new -testdatadir option has been added to test_aixcoin to allow specifying the location of unit test data directories. (#26564)

Blockstorage

Block files are now XOR’d by default with a key stored in the blocksdir. Previous releases of Aixcoin Core or previous external software will not be able to read the blocksdir with a non-zero XOR-key. Refer to the -blocksxor help for more details. (#28052)

Chainstate

The chainstate database flushes that occur when blocks are pruned will no longer empty the database cache. The cache will remain populated longer, which significantly reduces the time for initial block download to complete. (#28280)

Dependencies

The dependency on Boost.Process has been replaced with cpp-subprocess, which is contained in source. Builders will no longer need Boost.Process to build with external signer support. (#28981)

Aixcoin Core 27.0

Tue, 02 Apr 2024 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

27.0 Release Notes

Aixcoin Core version 27.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-27.0/

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux Kernel 3.17+, macOS 11.0+, and Windows 7 and newer. Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Aixcoin Core on unsupported systems.

Notable changes

libaixcoinconsensus

libaixcoinconsensus is deprecated and will be removed for v28. This library has existed for nearly 10 years with very little known uptake or impact. It has become a maintenance burden.

The underlying functionality does not change between versions, so any users of the library can continue to use the final release indefinitely, with the understanding that Taproot is its final consensus update.

In the future, libaixcoinkernel will provide a much more useful API that is aware of the UTXO set, and therefore be able to fully validate transactions and blocks. (#29189)

mempool.dat compatibility

The mempool.dat file created by -persistmempool or the savemempool RPC will be written in a new format. This new format includes the XOR’ing of transaction contents to mitigate issues where external programs (such as anti-virus) attempt to interpret and potentially modify the file.

This new format can not be read by previous software releases. To allow for a downgrade, a temporary setting -persistmempoolv1 has been added to fall back to the legacy format. (#28207)

P2P and network changes

BIP324 v2 transport is now enabled by default. It remains possible to disable v2 by running with -v2transport=0. (#29347)
Manual connection options (-connect, -addnode and -seednode) will now follow -v2transport to connect with v2 by default. They will retry with v1 on failure. (#29058)
Network-adjusted time has been removed from consensus code. It is replaced with (unadjusted) system time. The warning for a large median time offset (70 minutes or more) is kept. This removes the implicit security assumption of requiring an honest majority of outbound peers, and increases the importance of the node operator ensuring their system time is (and stays) correct to not fall out of consensus with the network. (#28956)

Mempool Policy Changes

Opt-in Topologically Restricted Until Confirmation (TRUC) Transactions policy (aka v3 transaction policy) is available for use on test networks when -acceptnonstdtxn=1 is set. By setting the transaction version number to 3, TRUC transactions request the application of limits on spending of their unconfirmed outputs. These restrictions simplify the assessment of incentive compatibility of accepting or replacing TRUC transactions, thus ensuring any replacements are more profitable for the node and making fee-bumping more reliable. TRUC transactions are currently nonstandard and can only be used on test networks where the standardness rules are relaxed or disabled (e.g. with -acceptnonstdtxn=1). (#28948)

External Signing

Support for external signing on Windows has been disabled. It will be re-enabled once the underlying dependency (Boost Process), has been replaced with a different library. (#28967)

Updated RPCs

The addnode RPC now follows the -v2transport option (now on by default, see above) for making connections. It remains possible to specify the transport type manually with the v2transport argument of addnode. (#29239)

Build System

A C++20 capable compiler is now required to build Aixcoin Core. (#28349)
MacOS releases are configured to use the hardened runtime libraries (#29127)

Wallet

The CoinGrinder coin selection algorithm has been introduced to mitigate unnecessary large input sets and lower transaction costs at high feerates. CoinGrinder searches for the input set with minimal weight. Solutions found by CoinGrinder will produce a change output. CoinGrinder is only active at elevated feerates (default: 30+ sat/vB, based on -consolidatefeerate×3). (#27877)
The Branch And Bound coin selection algorithm will be disabled when the subtract fee from outputs feature is used. (#28994)
If the birth time of a descriptor is detected to be later than the first transaction involving that descriptor, the birth time will be reset to the earlier time. (#28920)

Low-level changes

Pruning

When pruning during initial block download, more blocks will be pruned at each flush in order to speed up the syncing of such nodes. (#20827)

Init

Various fixes to prevent issues where subsequent instances of Aixcoin Core would result in deletion of files in use by an existing instance. (#28784, #28946)
Improved handling of empty settings.json files. (#29144)

Aixcoin Core 26.0

Wed, 06 Dec 2023 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

26.0 Release Notes

Aixcoin Core version 26.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-26.0/

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

How to Upgrade

Compatibility

Notable changes

P2P and network changes

Experimental support for the v2 transport protocol defined in BIP324 was added. It is off by default, but when enabled using -v2transport it will be negotiated on a per-connection basis with other peers that support it too. The existing v1 transport protocol remains fully supported.
Nodes with multiple reachable networks will actively try to have at least one outbound connection to each network. This improves individual resistance to eclipse attacks and network level resistance to partition attacks. Users no longer need to perform active measures to ensure being connected to multiple enabled networks. (#27213)

Pruning

When using assumeutxo with -prune, the prune budget may be exceeded if it is set lower than 1100MB (i.e. MIN_DISK_SPACE_FOR_BLOCK_FILES * 2). Prune budget is normally split evenly across each chainstate, unless the resulting prune budget per chainstate is beneath MIN_DISK_SPACE_FOR_BLOCK_FILES in which case that value will be used. (#27596)

Updated RPCs

Setting -rpcserialversion=0 is deprecated and will be removed in a future release. It can currently still be used by also adding the -deprecatedrpc=serialversion option. (#28448)
The hash_serialized_2 value has been removed from gettxoutsetinfo since the value it calculated contained a bug and did not take all data into account. It is superseded by hash_serialized_3 which provides the same functionality but serves the correctly calculated hash. (#28685)
New fields transport_protocol_type and session_id were added to the getpeerinfo RPC to indicate whether the v2 transport protocol is in use, and if so, what the session id is.
A new argument v2transport was added to the addnode RPC to indicate whether a v2 transaction connection is to be attempted with the peer.
Miniscript expressions can now be used in Taproot descriptors for all RPCs working with descriptors. (#27255)
finalizepsbt is now able to finalize a PSBT with inputs spending Miniscript-compatible Taproot leaves. (#27255)

Changes to wallet related RPCs can be found in the Wallet section below.

New RPCs

loadtxoutset has been added, which allows loading a UTXO snapshot of the format generated by dumptxoutset. Once this snapshot is loaded, its contents will be deserialized into a second chainstate data structure, which is then used to sync to the network’s tip.

Meanwhile, the original chainstate will complete the initial block download process in the background, eventually validating up to the block that the snapshot is based upon.

The result is a usable aixcoind instance that is current with the network tip in a matter of minutes rather than hours. UTXO snapshot are typically obtained via third-party sources (HTTP, torrent, etc.) which is reasonable since their contents are always checked by hash.

You can find more information on this process in the assumeutxo design document (https://github.com/aixcoin/aixcoin/blob/master/doc/design/assumeutxo.md).

getchainstates has been added to aid in monitoring the assumeutxo sync process.
A new getprioritisedtransactions RPC has been added. It returns a map of all fee deltas created by the user with prioritisetransaction, indexed by txid. The map also indicates whether each transaction is present in the mempool. (#27501)
A new RPC, submitpackage, has been added. It can be used to submit a list of raw hex transactions to the mempool to be evaluated as a package using consensus and mempool policy rules. These policies include package CPFP, allowing a child with high fees to bump a parent below the mempool minimum feerate (but not minimum relay feerate). (#27609)
- Warning: successful submission does not mean the transactions will propagate throughout the network, as package relay is not supported.
- Not all features are available. The package is limited to a child with all of its unconfirmed parents, and no parent may spend the output of another parent. Also, package RBF is not supported. Refer to doc/policy/packages.md for more details on package policies and limitations.
- This RPC is experimental. Its interface may change.
A new RPC getaddrmaninfo has been added to view the distribution of addresses in the new and tried table of the node’s address manager across different networks(ipv4, ipv6, onion, i2p, cjdns). The RPC returns count of addresses in new and tried table as well as their sum for all networks. (#27511)
A new importmempool RPC has been added. It loads a valid mempool.dat file and attempts to add its contents to the mempool. This can be useful to import mempool data from another node without having to modify the datadir contents and without having to restart the node. (#27460)
- Warning: Importing untrusted files is dangerous, especially if metadata from the file is taken over.
- If you want to apply fee deltas, it is recommended to use the getprioritisedtransactions and prioritisetransaction RPCs instead of the apply_fee_delta_priority option to avoid double-prioritising any already-prioritised transactions in the mempool.

Updated settings

aixcoind and aixcoin-qt will now raise an error on startup if a datadir that is being used contains a aixcoin.conf file that will be ignored, which can happen when a datadir= line is used in a aixcoin.conf file. The error message is just a diagnostic intended to prevent accidental misconfiguration, and it can be disabled to restore the previous behavior of using the datadir while ignoring the aixcoin.conf contained in it. (#27302)
Passing an invalid -debug, -debugexclude, or -loglevel logging configuration option now raises an error, rather than logging an easily missed warning. (#27632)

Changes to GUI or wallet related settings can be found in the GUI or Wallet section below.

New settings

Tools and Utilities

A new aixcoinconsensus_verify_script_with_spent_outputs function is available in libconsensus which optionally accepts the spent outputs of the transaction being verified.
A new aixcoinconsensus_SCRIPT_FLAGS_VERIFY_TAPROOT flag is available in libconsensus that will verify scripts with the Taproot spending rules.

Wallet

Wallet loading has changed in this release. Wallets with some corrupted records that could be previously loaded (with warnings) may no longer load. For example, wallets with corrupted address book entries may no longer load. If this happens, it is recommended load the wallet in a previous version of Aixcoin Core and import the data into a new wallet. Please also report an issue to help improve the software and make wallet loading more robust in these cases. (#24914)
The createwallet RPC will no longer create legacy (BDB) wallets when setting descriptors=false without also providing the -deprecatedrpc=create_bdb option. This is because the legacy wallet is being deprecated in a future release. (#28597)
The gettransaction, listtransactions, listsinceblock RPCs now return the abandoned field for all transactions. Previously, the “abandoned” field was only returned for sent transactions. (#25158)
The listdescriptors, decodepsbt and similar RPC methods now show h rather than apostrophe (') to indicate hardened derivation. This does not apply when using the private parameter, which matches the marker used when descriptor was generated or imported. Newly created wallets use h. This change makes it easier to handle descriptor strings manually. E.g. the importdescriptors RPC call is easiest to use h as the marker: '["desc": ".../0h/..."]'. With this change listdescriptors will use h, so you can copy-paste the result, without having to add escape characters or switch ' to ‘h’ manually. Note that this changes the descriptor checksum. For legacy wallets the hdkeypath field in getaddressinfo is unchanged, nor is the serialization format of wallet dumps. (#26076)
The getbalances RPC now returns a lastprocessedblock JSON object which contains the wallet’s last processed block hash and height at the time the balances were calculated. This result shouldn’t be cached because importing new keys could invalidate it. (#26094)
The gettransaction RPC now returns a lastprocessedblock JSON object which contains the wallet’s last processed block hash and height at the time the transaction information was generated. (#26094)
The getwalletinfo RPC now returns a lastprocessedblock JSON object which contains the wallet’s last processed block hash and height at the time the wallet information was generated. (#26094)
Coin selection and transaction building now accounts for unconfirmed low-feerate ancestor transactions. When it is necessary to spend unconfirmed outputs, the wallet will add fees to ensure that the new transaction with its ancestors will achieve a mining score equal to the feerate requested by the user. (#26152)
For RPC methods which accept options parameters ((importmulti, listunspent, fundrawtransaction, bumpfee, send, sendall, walletcreatefundedpsbt, simulaterawtransaction), it is now possible to pass the options as named parameters without the need for a nested object. (#26485)

This means it is possible make calls like:

src/aixcoin-cli -named bumpfee txid fee_rate=100

instead of

src/aixcoin-cli -named bumpfee txid options='{"fee_rate": 100}'

The deprecatedrpc=walletwarningfield configuration option has been removed. The createwallet, loadwallet, restorewallet and unloadwallet RPCs no longer return the “warning” string field. The same information is provided through the “warnings” field added in v25.0, which returns a JSON array of strings. The “warning” string field was deprecated also in v25.0. (#27757)
The signrawtransactionwithkey, signrawtransactionwithwallet, walletprocesspsbt and descriptorprocesspsbt calls now return the more specific RPC_INVALID_PARAMETER error instead of RPC_MISC_ERROR if their sighashtype argument is malformed. (#28113)
RPC walletprocesspsbt, and descriptorprocesspsbt return object now includes field hex (if the transaction is complete) containing the serialized transaction suitable for RPC sendrawtransaction. (#28414)
It’s now possible to use Miniscript inside Taproot leaves for descriptor wallets. (#27255)

Descriptors

The usage of hybrid public keys in output descriptors has been removed. Hybrid public keys are an exotic public key encoding not supported by output descriptors (as specified in BIP380 and documented in doc/descriptors.md). Aixcoin Core would previously incorrectly accept descriptors containing such hybrid keys. (#28587)

GUI changes

The transaction list in the GUI no longer provides a special category for “payment to yourself”. Now transactions that have both inputs and outputs that affect the wallet are displayed on separate lines for spending and receiving. (gui#119)
A new menu option allows migrating a legacy wallet based on keys and implied output script types stored in BerkeleyDB (BDB) to a modern wallet that uses descriptors stored in SQLite. (gui#738)
The PSBT operations dialog marks outputs paying your own wallet with “own address”. (gui#740)
The ability to create legacy wallets is being removed. (gui#764)

Contrib

Bash completion files have been renamed from aixcoin*.bash-completion to aixcoin*.bash. This means completions can be automatically loaded on demand based on invoked commands’ names when they are put into the completion directory (found with pkg-config --variable=completionsdir bash-completion) without requiring renaming. (#28507)

Low-level changes

Tests

Non-standard transactions are now disabled by default on testnet for relay and mempool acceptance. The previous behaviour can be re-enabled by setting -acceptnonstdtxn=1. (#28354)

Aixcoin Core 25.0

Fri, 26 May 2023 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

25.0 Release Notes

Aixcoin Core version 25.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-25.0/

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Compatibility

Notable changes

P2P and network changes

Transactions of non-witness size 65 bytes and above are now allowed by mempool and relay policy. This is to better reflect the actual afforded protections against CVE-2017-12842 and open up additional use-cases of smaller transaction sizes. (#26265)

New RPCs

The scanblocks RPC returns the relevant blockhashes from a set of descriptors by scanning all blockfilters in the given range. It can be used in combination with the getblockheader and rescanblockchain RPCs to achieve fast wallet rescans. Note that this functionality can only be used if a compact block filter index (-blockfilterindex=1) has been constructed by the node. (#23549)

Updated RPCs

All JSON-RPC methods accept a new named parameter called args that can contain positional parameter values. This is a convenience to allow some parameter values to be passed by name without having to name every value. The python test framework and aixcoin-cli tool both take advantage of this, so for example:

aixcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1

Can now be shortened to:

aixcoin-cli -named createwallet mywallet load_on_startup=1

The verifychain RPC will now return false if the checks didn’t fail, but couldn’t be completed at the desired depth and level. This could be due to missing data while pruning, due to an insufficient dbcache or due to the node being shutdown before the call could finish. (#25574)
sendrawtransaction has a new, optional argument, maxburnamount with a default value of 0. Any transaction containing an unspendable output with a value greater than maxburnamount will not be submitted. At present, the outputs deemed unspendable are those with scripts that begin with an OP_RETURN code (known as ‘datacarriers’), scripts that exceed the maximum script size, and scripts that contain invalid opcodes.
The testmempoolaccept RPC now returns 2 additional results within the “fees” result: “effective-feerate” is the feerate including fees and sizes of transactions validated together if package validation was used, and also includes any modified fees from prioritisetransaction. The “effective-includes” result lists the wtxids of transactions whose modified fees and sizes were used in the effective-feerate (#26646).
decodescript may now infer a Miniscript descriptor under P2WSH context if it is not lacking information. (#27037)
finalizepsbt is now able to finalize a transaction with inputs spending Miniscript-compatible P2WSH scripts. (#24149)

Changes to wallet related RPCs can be found in the Wallet section below.

Build System

The --enable-upnp-default and --enable-natpmp-default options have been removed. If you want to use port mapping, you can configure it using a .conf file, or by passing the relevant options at runtime. (#26896)

Updated settings

If the -checkblocks or -checklevel options are explicitly provided by the user, but the verification checks cannot be completed due to an insufficient dbcache, Aixcoin Core will now return an error at startup. (#25574)
Ports specified in -port and -rpcport options are now validated at startup. Values that previously worked and were considered valid can now result in errors. (#22087)
Setting -blocksonly will now reduce the maximum mempool memory to 5MB (users may still use -maxmempool to override). Previously, the default 300MB would be used, leading to unexpected memory usage for users running with -blocksonly expecting it to eliminate mempool memory usage.

As unused mempool memory is shared with dbcache, this also reduces the dbcache size for users running with -blocksonly, potentially impacting performance.
Setting -maxconnections=0 will now disable -dnsseed and -listen (users may still set them to override).

Changes to GUI or wallet related settings can be found in the GUI or Wallet section below.

New settings

The shutdownnotify option is used to specify a command to execute synchronously before Aixcoin Core has begun its shutdown sequence. (#23395)

Wallet

The minconf option, which allows a user to specify the minimum number of confirmations a UTXO being spent has, and the maxconf option, which allows specifying the maximum number of confirmations, have been added to the following RPCs in #25375:
- fundrawtransaction
- send
- walletcreatefundedpsbt
- sendall
Added a new next_index field in the response in listdescriptors to have the same format as importdescriptors (#26194)
RPC listunspent now has a new argument include_immature_coinbase to include coinbase UTXOs that don’t meet the minimum spendability depth requirement (which before were silently skipped). (#25730)
Rescans for descriptor wallets are now significantly faster if compact block filters (BIP158) are available. Since those are not constructed by default, the configuration option “-blockfilterindex=1” has to be provided to take advantage of the optimization. This improves the performance of the RPC calls rescanblockchain, importdescriptors and restorewallet. (#25957)
RPC unloadwallet now fails if a rescan is in progress. (#26618)
Wallet passphrases may now contain null characters. Prior to this change, only characters up to the first null character were recognized and accepted. (#27068)
Address Purposes strings are now restricted to the currently known values of “send”, “receive”, and “refund”. Wallets that have unrecognized purpose strings will have loading warnings, and the listlabels RPC will raise an error if an unrecognized purpose is requested. (#27217)
In the createwallet, loadwallet, unloadwallet, and restorewallet RPCs, the “warning” string field is deprecated in favor of a “warnings” field that returns a JSON array of strings to better handle multiple warning messages and for consistency with other wallet RPCs. The “warning” field will be fully removed from these RPCs in v26. It can be temporarily re-enabled during the deprecation period by launching aixcoind with the configuration option -deprecatedrpc=walletwarningfield. (#27279)
Descriptor wallets can now spend coins sent to P2WSH Miniscript descriptors. (#24149)

GUI changes

The “Mask values” is a persistent option now. (gui#701)
The “Mask values” option affects the “Transaction” view now, in addition to the “Overview” one. (gui#708)

REST

A new /rest/deploymentinfo endpoint has been added for fetching various state info regarding deployments of consensus changes. (#25412)

Binary verification

The binary verification script has been updated. In previous releases it would verify that the binaries had been signed with a single “release key”. In this release and moving forward it will verify that the binaries are signed by a threshold of trusted keys. For more details and examples, see: https://github.com/aixcoin/aixcoin/blob/master/contrib/verify-binaries/README.md (#27358)

Low-level changes

RPC

The JSON-RPC server now rejects requests where a parameter is specified multiple times with the same name, instead of silently overwriting earlier parameter values with later ones. (#26628)
RPC listsinceblock now accepts an optional label argument to fetch incoming transactions having the specified label. (#25934)
Previously setban, addpeeraddress, walletcreatefundedpsbt, methods allowed non-boolean and non-null values to be passed as boolean parameters. Any string, number, array, or object value that was passed would be treated as false. After this change, passing any value except true, false, or null now triggers a JSON value is not of expected type error. (#26213)

Notice of new option for transaction replacement policies

This version of Aixcoin Core adds a new mempoolfullrbf configuration option which allows users to change the policy their individual node will use for relaying and mining unconfirmed transactions. The option defaults to the same policy that was used in previous releases and no changes to node policy will occur if everyone uses the default.

Some Aixcoin services today expect that the first version of an unconfirmed transaction that they see will be the version of the transaction that ultimately gets confirmed—a transaction acceptance policy sometimes called “first-seen”.

The Aixcoin Protocol does not, and cannot, provide any assurance that the first version of an unconfirmed transaction seen by a particular node will be the version that gets confirmed. If there are multiple versions of the same unconfirmed transaction available, only the miner who includes one of those transactions in a block gets to decide which version of the transaction gets confirmed.

Despite this lack of assurance, multiple merchants and services today still make this assumption.

There are several benefits to users from removing this first-seen simplification. One key benefit, the ability for the sender of a transaction to replace it with an alternative version paying higher fees, was realized in Aixcoin Core 0.12.0 (February 2016) with the introduction of BIP125 opt-in Replace By Fee (RBF).

Since then, there has been discussion about completely removing the first-seen simplification and allowing users to replace any of their older unconfirmed transactions with newer transactions, a feature called full-RBF. This release includes a mempoolfullrbf configuration option that allows enabling full-RBF, although it defaults to off (allowing only opt-in RBF).

Several alternative node implementations have already enabled full-RBF by default for years, and several contributors to Aixcoin Core are advocating for enabling full-RBF by default in a future version of Aixcoin Core.

As more nodes that participate in relay and mining begin enabling full-RBF, replacement of unconfirmed transactions by ones offering higher fees may rapidly become more reliable.

Contributors to this project strongly recommend that merchants and services not accept unconfirmed transactions as final, and if they insist on doing so, to take the appropriate steps to ensure they have some recourse or plan for when their assumptions do not hold.

Notable changes

P2P and network changes

To address a potential denial-of-service, the logic to download headers from peers has been reworked. This is particularly relevant for nodes starting up for the first time (or for nodes which are starting up after being offline for a long time).

Whenever headers are received from a peer that have a total chainwork that is either less than the node’s -minimumchainwork value or is sufficiently below the work at the node’s tip, a “presync” phase will begin, in which the node will download the peer’s headers and verify the cumulative work on the peer’s chain, prior to storing those headers permanently. Once that cumulative work is verified to be sufficiently high, the headers will be redownloaded from that peer and fully validated and stored.

This may result in initial headers sync taking longer for new nodes starting up for the first time, both because the headers will be downloaded twice, and because the effect of a peer disconnecting during the presync phase (or while the node’s best headers chain has less than -minimumchainwork), will result in the node needing to use the headers presync mechanism with the next peer as well (downloading the headers twice, again). (#25717)
With I2P connections, a new, transient address is used for each outbound connection if -i2pacceptincoming=0. (#25355)

Updated RPCs

The -deprecatedrpc=softforks configuration option has been removed. The RPC getblockchaininfo no longer returns the softforks field, which was previously deprecated in 23.0. (#23508) Information on soft fork status is now only available via the getdeploymentinfo RPC.
The deprecatedrpc=exclude_coinbase configuration option has been removed. The receivedby RPCs (listreceivedbyaddress, listreceivedbylabel, getreceivedbyaddress and getreceivedbylabel) now always return results accounting for received coins from coinbase outputs, without an option to change that behaviour. Excluding coinbases was previously deprecated in 23.0. (#25171)
The deprecatedrpc=fees configuration option has been removed. The top-level fee fields fee, modifiedfee, ancestorfees and descendantfees are no longer returned by RPCs getmempoolentry, getrawmempool(verbose=true), getmempoolancestors(verbose=true) and getmempooldescendants(verbose=true). The same fee fields can be accessed through the fees object in the result. The top-level fee fields were previously deprecated in 23.0. (#25204)
The getpeerinfo RPC has been updated with a new presynced_headers field, indicating the progress on the presync phase mentioned in the “P2P and network changes” section above.

Changes to wallet related RPCs can be found in the Wallet section below.

New RPCs

The sendall RPC spends specific UTXOs to one or more recipients without creating change. By default, the sendall RPC will spend every UTXO in the wallet. sendall is useful to empty wallets or to create a changeless payment from select UTXOs. When creating a payment from a specific amount for which the recipient incurs the transaction fee, continue to use the subtractfeefromamount option via the send, sendtoaddress, or sendmany RPCs. (#24118)
A new gettxspendingprevout RPC has been added, which scans the mempool to find transactions spending any of the given outpoints. (#24408)
The simulaterawtransaction RPC iterates over the inputs and outputs of the given transactions, and tallies up the balance change for the given wallet. This can be useful e.g. when verifying that a coin join like transaction doesn’t contain unexpected inputs that the wallet will then sign for unintentionally. (#22751)

Updated REST APIs

The /headers/ and /blockfilterheaders/ endpoints have been updated to use a query parameter instead of path parameter to specify the result count. The count parameter is now optional, and defaults to 5 for both endpoints. The old endpoints are still functional, and have no documented behaviour change.

For /headers, use GET /rest/headers/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5> instead of GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json> (deprecated)

For /blockfilterheaders/, use GET /rest/blockfilterheaders/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5> instead of GET /rest/blockfilterheaders/<FILTERTYPE>/<COUNT>/<BLOCK-HASH>.<bin|hex|json> (deprecated)

(#24098)

Build System

Guix builds are now reproducible across architectures (x86_64 & aarch64). (#21194)

New settings

A new mempoolfullrbf option has been added, which enables the mempool to accept transaction replacement without enforcing BIP125 replaceability signaling. (#25353)

Wallet

The -walletrbf startup option will now default to true. The wallet will now default to opt-in RBF on transactions that it creates. (#25610)
The replaceable option for the createrawtransaction and createpsbt RPCs will now default to true. Transactions created with these RPCs will default to having opt-in RBF enabled. (#25610)
The wsh() output descriptor was extended with Miniscript support. You can import Miniscript descriptors for P2WSH in a watchonly wallet to track coins, but you can’t spend from them using the Aixcoin Core wallet yet. You can find more about Miniscript on the reference website. (#24148)
The tr() output descriptor now supports multisig scripts through the multi_a() and sortedmulti_a() functions. (#24043)
To help prevent fingerprinting transactions created by the Aixcoin Core wallet, change output amounts are now randomized. (#24494)
The listtransactions, gettransaction, and listsinceblock RPC methods now include a wtxid field (hash of serialized transaction, including witness data) for each transaction. (#24198)
The listsinceblock, listtransactions and gettransaction output now contain a new parent_descs field for every “receive” entry. (#25504)
A new optional include_change parameter was added to the listsinceblock command.
RPC getreceivedbylabel now returns an error, “Label not found in wallet” (-4), if the label is not in the address book. (#25122)

Migrating Legacy Wallets to Descriptor Wallets

An experimental RPC migratewallet has been added to migrate Legacy (non-descriptor) wallets to Descriptor wallets. More information about the migration process is available in the documentation.

GUI changes

A new menu item to restore a wallet from a backup file has been added (gui#471).
Configuration changes made in the aixcoin GUI (such as the pruning setting, proxy settings, UPNP preferences) are now saved to <datadir>/settings.json file rather than to the Qt settings backend (windows registry or unix desktop config files), so these settings will now apply to aixcoind, instead of being ignored. (#15936, gui#602)
Also, the interaction between GUI settings and aixcoin.conf settings is simplified. Settings from aixcoin.conf are now displayed normally in the GUI settings dialog, instead of in a separate warning message (“Options set in this dialog are overridden by the configuration file: -setting=value”). And these settings can now be edited because settings.json values take precedence over aixcoin.conf values. (#15936)

Low-level changes

RPC

The deriveaddresses, getdescriptorinfo, importdescriptors and scantxoutset commands now accept Miniscript expression within a wsh() descriptor. (#24148)
The getaddressinfo, decodescript, listdescriptors and listunspent commands may now output a Miniscript descriptor inside a wsh() where a wsh(raw()) descriptor was previously returned. (#24148)

Aixcoin Core 23.0

Mon, 25 Apr 2022 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

23.0 Release Notes

Aixcoin Core version 23.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-23.0/

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Compatibility

Notable changes

P2P and network changes

A aixcoind node will no longer rumour addresses to inbound peers by default. They will become eligible for address gossip after sending an ADDR, ADDRV2, or GETADDR message. (#21528)
Before this release, Aixcoin Core had a strong preference to try to connect only to peers that listen on port 8333. As a result of that, Aixcoin nodes listening on non-standard ports would likely not get any Aixcoin Core peers connecting to them. This preference has been removed. (#23542)
Full support has been added for the CJDNS network. See the new option -cjdnsreachable and doc/cjdns.md (#23077)

Fee estimation changes

Fee estimation now takes the feerate of replacement (RBF) transactions into account. (#22539)

Rescan startup parameter removed

The -rescan startup parameter has been removed. Wallets which require rescanning due to corruption will still be rescanned on startup. Otherwise, please use the rescanblockchain RPC to trigger a rescan. (#23123)

Tracepoints and Userspace, Statically Defined Tracing support

Aixcoin Core release binaries for Linux now include experimental tracepoints which act as an interface for process-internal events. These can be used for review, debugging, monitoring, and more. The tracepoint API is semi-stable. While the API is tested, process internals might change between releases requiring changes to the tracepoints. Information about the existing tracepoints can be found under doc/tracing.md and usage examples are provided in contrib/tracing/.

Updated RPCs

The validateaddress RPC now returns an error_locations array for invalid addresses, with the indices of invalid character locations in the address (if known). For example, this will attempt to locate up to two Bech32 errors, and return their locations if successful. Success and correctness are only guaranteed if fewer than two substitution errors have been made. The error message returned in the error field now also returns more specific errors when decoding fails. (#16807)
The -deprecatedrpc=addresses configuration option has been removed. RPCs gettxout, getrawtransaction, decoderawtransaction, decodescript, gettransaction verbose=true and REST endpoints /rest/tx, /rest/getutxos, /rest/block no longer return the addresses and reqSigs fields, which were previously deprecated in 22.0. (#22650)
The getblock RPC command now supports verbosity level 3 containing transaction inputs’ prevout information. The existing /rest/block/ REST endpoint is modified to contain this information too. Every vin field will contain an additional prevout subfield describing the spent output. prevout contains the following keys:
- generated - true if the spent coins was a coinbase.
- height
- value
- scriptPubKey
The top-level fee fields fee, modifiedfee, ancestorfees and descendantfees returned by RPCs getmempoolentry,getrawmempool(verbose=true), getmempoolancestors(verbose=true) and getmempooldescendants(verbose=true) are deprecated and will be removed in the next major version (use -deprecated=fees if needed in this version). The same fee fields can be accessed through the fees object in the result. WARNING: deprecated fields ancestorfees and descendantfees are denominated in sats, whereas all fields in the fees object are denominated in AIX. (#22689)
Both createmultisig and addmultisigaddress now include a warnings field, which will show a warning if a non-legacy address type is requested when using uncompressed public keys. (#23113)

Changes to wallet related RPCs can be found in the Wallet section below.

New RPCs

Information on soft fork status has been moved from getblockchaininfo to the new getdeploymentinfo RPC which allows querying soft fork status at any block, rather than just at the chain tip. Inclusion of soft fork status in getblockchaininfo can currently be restored using the configuration -deprecatedrpc=softforks, but this will be removed in a future release. Note that in either case, the status field now reflects the status of the current block rather than the next block. (#23508)

Files

On startup, the list of banned hosts and networks (via setban RPC) in banlist.dat is ignored and only banlist.json is considered. Aixcoin Core version 22.x is the only version that can read banlist.dat and also write it to banlist.json. If banlist.json already exists, version 22.x will not try to translate the banlist.dat into json. After an upgrade, listbanned can be used to double check the parsed entries. (#22570)

Updated settings

In previous releases, the meaning of the command line option -persistmempool (without a value provided) incorrectly disabled mempool persistence. -persistmempool is now treated like other boolean options to mean -persistmempool=1. Passing -persistmempool=0, -persistmempool=1 and -nopersistmempool is unaffected. (#23061)
-maxuploadtarget now allows human readable byte units [k|K|m|M|g|G|t|T]. E.g. -maxuploadtarget=500g. No whitespace, +- or fractions allowed. Default is M if no suffix provided. (#23249)
If -proxy= is given together with -noonion then the provided proxy will not be set as a proxy for reaching the Tor network. So it will not be possible to open manual connections to the Tor network for example with the addnode RPC. To mimic the old behavior use -proxy= together with -onlynet= listing all relevant networks except onion. (#22834)

Tools and Utilities

Update -getinfo to return data in a user-friendly format that also reduces vertical space. (#21832)
CLI -addrinfo now returns a single field for the number of onion addresses known to the node instead of separate torv2 and torv3 fields, as support for Tor V2 addresses was removed from Aixcoin Core in 22.0. (#22544)

Wallet

Descriptor wallets are now the default wallet type. Newly created wallets will use descriptors unless descriptors=false is set during createwallet, or the Descriptor wallet checkbox is unchecked in the GUI.

Note that wallet RPC commands like importmulti and dumpprivkey cannot be used with descriptor wallets, so if your client code relies on these commands without specifying descriptors=false during wallet creation, you will need to update your code.
Newly created descriptor wallets will contain an automatically generated tr() descriptor which allows for creating single key Taproot receiving addresses.
upgradewallet will now automatically flush the keypool if upgrading from a non-HD wallet to an HD wallet, to immediately start using the newly-generated HD keys. (#23093)
a new RPC newkeypool has been added, which will flush (entirely clear and refill) the keypool. (#23093)
listunspent now includes ancestorcount, ancestorsize, and ancestorfees for each transaction output that is still in the mempool. (#12677)
lockunspent now optionally takes a third parameter, persistent, which causes the lock to be written persistently to the wallet database. This allows UTXOs to remain locked even after node restarts or crashes. (#23065)
receivedby RPCs now include coinbase transactions. Previously, the following wallet RPCs excluded coinbase transactions: getreceivedbyaddress, getreceivedbylabel, listreceivedbyaddress, listreceivedbylabel. This release changes this behaviour and returns results accounting for received coins from coinbase outputs. The previous behaviour can be restored using the configuration -deprecatedrpc=exclude_coinbase, but may be removed in a future release. (#14707)
A new option in the same receivedby RPCs, include_immature_coinbase (default=false), determines whether to account for immature coinbase transactions. Immature coinbase transactions are coinbase transactions that have 100 or fewer confirmations, and are not spendable. (#14707)

GUI changes

UTXOs which are locked via the GUI are now stored persistently in the wallet database, so are not lost on node shutdown or crash. (#23065)
The Bech32 checkbox has been replaced with a dropdown for all address types, including the new Bech32m (BIP-350) standard for Taproot enabled wallets.

Low-level changes

RPC

getblockchaininfo now returns a new time field, that provides the chain tip time. (#22407)

Tests

For the regtest network the activation heights of several softforks were set to block height 1. They can be changed by the runtime setting -testactivationheight=name@height. (#22818)

How to Upgrade

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.14+, and Windows 7 and newer. Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Aixcoin Core on unsupported systems.

From Aixcoin Core 22.0 onwards, macOS versions earlier than 10.14 are no longer supported.

Notable changes

Updated settings

In previous releases, the meaning of the command line option -persistmempool (without a value provided) incorrectly disabled mempool persistence. -persistmempool is now treated like other boolean options to mean -persistmempool=1. Passing -persistmempool=0, -persistmempool=1 and -nopersistmempool is unaffected. (#23061)

Aixcoin Core 22.0

Mon, 13 Sep 2021 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

22.0 Release Notes

Aixcoin Core version 22.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-22.0/

This release includes new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Compatibility

From Aixcoin Core 22.0 onwards, macOS versions earlier than 10.14 are no longer supported.

Notable changes

P2P and network changes

Added support for running Aixcoin Core as an I2P (Invisible Internet Project) service and connect to such services. See i2p.md for details. (#20685)
This release removes support for Tor version 2 hidden services in favor of Tor v3 only, as the Tor network dropped support for Tor v2 with the release of Tor version 0.4.6. Henceforth, Aixcoin Core ignores Tor v2 addresses; it neither rumors them over the network to other peers, nor stores them in memory or to peers.dat. (#22050)
Added NAT-PMP port mapping support via libnatpmp. (#18077)

New and Updated RPCs

Due to BIP 350 being implemented, behavior for all RPCs that accept addresses is changed when a native witness version 1 (or higher) is passed. These now require a Bech32m encoding instead of a Bech32 one, and Bech32m encoding will be used for such addresses in RPC output as well. No version 1 addresses should be created for mainnet until consensus rules are adopted that give them meaning (as will happen through BIP 341). Once that happens, Bech32m is expected to be used for them, so this shouldn’t affect any production systems, but may be observed on other networks where such addresses already have meaning (like signet). (#20861)
The getpeerinfo RPC returns two new boolean fields, bip152_hb_to and bip152_hb_from, that respectively indicate whether we selected a peer to be in compact blocks high-bandwidth mode or whether a peer selected us as a compact blocks high-bandwidth peer. High-bandwidth peers send new block announcements via a cmpctblock message rather than the usual inv/headers announcements. See BIP 152 for more details. (#19776)
getpeerinfo no longer returns the following fields: addnode, banscore, and whitelisted, which were previously deprecated in 0.21. Instead of addnode, the connection_type field returns manual. Instead of whitelisted, the permissions field indicates if the peer has special privileges. The banscore field has simply been removed. (#20755)
The following RPCs: gettxout, getrawtransaction, decoderawtransaction, decodescript, gettransaction, and REST endpoints: /rest/tx, /rest/getutxos, /rest/block deprecated the following fields (which are no longer returned in the responses by default): addresses, reqSigs. The -deprecatedrpc=addresses flag must be passed for these fields to be included in the RPC response. This flag/option will be available only for this major release, after which the deprecation will be removed entirely. Note that these fields are attributes of the scriptPubKey object returned in the RPC response. However, in the response of decodescript these fields are top-level attributes, and included again as attributes of the scriptPubKey object. (#20286)
When creating a hex-encoded aixcoin transaction using the aixcoin-tx utility with the -json option set, the following fields: addresses, reqSigs are no longer returned in the tx output of the response. (#20286)
The listbanned RPC now returns two new numeric fields: ban_duration and time_remaining. Respectively, these new fields indicate the duration of a ban and the time remaining until a ban expires, both in seconds. Additionally, the ban_created field is repositioned to come before banned_until. (#21602)
The setban RPC can ban onion addresses again. This fixes a regression introduced in version 0.21.0. (#20852)
The getnodeaddresses RPC now returns a “network” field indicating the network type (ipv4, ipv6, onion, or i2p) for each address. (#21594)
getnodeaddresses now also accepts a “network” argument (ipv4, ipv6, onion, or i2p) to return only addresses of the specified network. (#21843)
The testmempoolaccept RPC now accepts multiple transactions (still experimental at the moment, API may be unstable). This is intended for testing transaction packages with dependency relationships; it is not recommended for batch-validating independent transactions. In addition to mempool policy, package policies apply: the list cannot contain more than 25 transactions or have a total size exceeding 101K virtual bytes, and cannot conflict with (spend the same inputs as) each other or the mempool, even if it would be a valid BIP125 replace-by-fee. There are some known limitations to the accuracy of the test accept: it’s possible for testmempoolaccept to return “allowed”=True for a group of transactions, but “too-long-mempool-chain” if they are actually submitted. (#20833)
addmultisigaddress and createmultisig now support up to 20 keys for Segwit addresses. (#20867)

Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section below.

Build System

Release binaries are now produced using the new guix-based build system. The /doc/release-process.md document has been updated accordingly.

Files

The list of banned hosts and networks (via setban RPC) is now saved on disk in JSON format in banlist.json instead of banlist.dat. banlist.dat is only read on startup if banlist.json is not present. Changes are only written to the new banlist.json. A future version of Aixcoin Core may completely ignore banlist.dat. (#20966)

New settings

The -natpmp option has been added to use NAT-PMP to map the listening port. If both UPnP and NAT-PMP are enabled, a successful allocation from UPnP prevails over one from NAT-PMP. (#18077)

Updated settings

Changes to Wallet or GUI related settings can be found in the GUI or Wallet section below.

Passing an invalid -rpcauth argument now cause aixcoind to fail to start. (#20461)

Tools and Utilities

A new CLI -addrinfo command returns the number of addresses known to the node per network type (including Tor v2 versus v3) and total. This can be useful to see if the node knows enough addresses in a network to use options like -onlynet=<network> or to upgrade to this release of Aixcoin Core 22.0 that supports Tor v3 only. (#21595)
A new -rpcwaittimeout argument to aixcoin-cli sets the timeout in seconds to use with -rpcwait. If the timeout expires, aixcoin-cli will report a failure. (#21056)

Wallet

External signers such as hardware wallets can now be used through the new RPC methods enumeratesigners and displayaddress. Support is also added to the send RPC call. This feature is experimental. See external-signer.md for details. (#16546)
A new listdescriptors RPC is available to inspect the contents of descriptor-enabled wallets. The RPC returns public versions of all imported descriptors, including their timestamp and flags. For ranged descriptors, it also returns the range boundaries and the next index to generate addresses from. (#20226)
The bumpfee RPC is not available with wallets that have private keys disabled. psbtbumpfee can be used instead. (#20891)
The fundrawtransaction, send and walletcreatefundedpsbt RPCs now support an include_unsafe option that when true allows using unsafe inputs to fund the transaction. Note that the resulting transaction may become invalid if one of the unsafe inputs disappears. If that happens, the transaction must be funded with different inputs and republished. (#21359)
We now support up to 20 keys in multi() and sortedmulti() descriptors under wsh(). (#20867)
Taproot descriptors can be imported into the wallet only after activation has occurred on the network (e.g. mainnet, testnet, signet) in use. See descriptors.md for supported descriptors.

GUI changes

External signers such as hardware wallets can now be used. These require an external tool such as HWI to be installed and configured under Options -> Wallet. When creating a new wallet a new option “External signer” will appear in the dialog. If the device is detected, its name is suggested as the wallet name. The watch-only keys are then automatically imported. Receive addresses can be verified on the device. The send dialog will automatically use the connected device. This feature is experimental and the UI may freeze for a few seconds when performing these actions.

Low-level changes

RPC

The RPC server can process a limited number of simultaneous RPC requests. Previously, if this limit was exceeded, the RPC server would respond with status code 500 (HTTP_INTERNAL_SERVER_ERROR). Now it returns status code 503 (HTTP_SERVICE_UNAVAILABLE). (#18335)
Error codes have been updated to be more accurate for the following error cases (#18466):
- signmessage now returns RPC_INVALID_ADDRESS_OR_KEY (-5) if the passed address is invalid. Previously returned RPC_TYPE_ERROR (-3).
- verifymessage now returns RPC_INVALID_ADDRESS_OR_KEY (-5) if the passed address is invalid. Previously returned RPC_TYPE_ERROR (-3).
- verifymessage now returns RPC_TYPE_ERROR (-3) if the passed signature is malformed. Previously returned RPC_INVALID_ADDRESS_OR_KEY (-5).

How to Upgrade

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.12+, and Windows 7 and newer. Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them. It is not recommended to use Aixcoin Core on unsupported systems.

From Aixcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no longer supported. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

How to Upgrade

Compatibility

From Aixcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no longer supported. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

Notable changes

Taproot Soft Fork

Included in this release are the mainnet and testnet activation parameters for the taproot soft fork (BIP341) which also adds support for schnorr signatures (BIP340) and tapscript (BIP342).

If activated, these improvements will allow users of single-signature scripts, multisignature scripts, and complex contracts to all use identical-appearing commitments that enhance their privacy and the fungibility of all aixcoins. Spenders will enjoy lower fees and the ability to resolve many multisig scripts and complex contracts with the same efficiency, low fees, and large anonymity set as single-sig users. Taproot and schnorr also include efficiency improvements for full nodes such as the ability to batch signature verification. Together, the improvements lay the groundwork for future potential upgrades that may improve efficiency, privacy, and fungibility further.

Activation for taproot is being managed using a variation of BIP9 versionbits called Speedy Trial (described in BIP341). Taproot’s versionbit is bit 2, and nodes will begin tracking which blocks signal support for taproot at the beginning of the first retarget period after taproot’s start date of 24 April 2021. If 90% of blocks within a 2,016-block retarget period (about two weeks) signal support for taproot prior to the first retarget period beginning after the time of 11 August 2021, the soft fork will be locked in, and taproot will then be active as of block 709632 (expected in early or mid November).

Should taproot not be locked in via Speedy Trial activation, it is expected that a follow-up activation mechanism will be deployed, with changes to address the reasons the Speedy Trial method failed.

This release includes the ability to pay taproot addresses, although payments to such addresses are not secure until taproot activates. It also includes the ability to relay and mine taproot transactions after activation. Beyond those two basic capabilities, this release does not include any code that allows anyone to directly use taproot. The addition of taproot-related features to Aixcoin Core’s wallet is expected in later releases once taproot activation is assured.

All users, businesses, and miners are encouraged to upgrade to this release (or a subsequent compatible release) unless they object to activation of taproot. If taproot is locked in, then upgrading before block 709632 is highly recommended to help enforce taproot’s new rules and to avoid the unlikely case of seeing falsely confirmed transactions.

Miners who want to activate Taproot should preferably use this release to control their signaling. The getblocktemplate RPC results will automatically be updated to signal once the appropriate start has been reached and continue signaling until the timeout occurs or taproot activates. Alternatively, miners may manually start signaling on bit 2 at any time; if taproot activates, they will need to ensure they update their nodes before block 709632 or non-upgraded nodes could cause them to mine on an invalid chain. See the versionbits FAQ for details.

Updated RPCs

Due to BIP 350 being implemented, behavior for all RPCs that accept addresses is changed when a native witness version 1 (or higher) is passed. These now require a Bech32m encoding instead of a Bech32 one, and Bech32m encoding will be used for such addresses in RPC output as well. No version 1 addresses should be created for mainnet until consensus rules are adopted that give them meaning (e.g. through BIP 341). Once that happens, Bech32m is expected to be used for them, so this shouldn’t affect any production systems, but may be observed on other networks where such addresses already have meaning (like signet).

How to Upgrade

Compatibility

From Aixcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no longer supported. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

The node’s known peers are persisted to disk in a file called peers.dat. The format of this file has been changed in a backwards-incompatible way in order to accommodate the storage of Tor v3 and other BIP155 addresses. This means that if the file is modified by 0.21.0 or newer then older versions will not be able to read it. Those old versions, in the event of a downgrade, will log an error message “Incorrect keysize in addrman deserialization” and will continue normal operation as if the file was missing, creating a new empty one. (#19954, #20284)

Notable changes

P2P and network changes

The mempool now tracks whether transactions submitted via the wallet or RPCs have been successfully broadcast. Every 10-15 minutes, the node will try to announce unbroadcast transactions until a peer requests it via a getdata message or the transaction is removed from the mempool for other reasons. The node will not track the broadcast status of transactions submitted to the node using P2P relay. This version reduces the initial broadcast guarantees for wallet transactions submitted via P2P to a node running the wallet. (#18038)
The size of the set of transactions that peers have announced and we consider for requests has been reduced from 100000 to 5000 (per peer), and further announcements will be ignored when that limit is reached. If you need to dump (very) large batches of transactions, exceptions can be made for trusted peers using the “relay” network permission. For localhost for example it can be enabled using the command line option -whitelist=relay@127.0.0.1. (#19988)
This release adds support for Tor version 3 hidden services, and rumoring them over the network to other peers using BIP155. Version 2 hidden services are still fully supported by Aixcoin Core, but the Tor network will start deprecating them in the coming months. (#19954)
The Tor onion service that is automatically created by setting the -listenonion configuration parameter will now be created as a Tor v3 service instead of Tor v2. The private key that was used for Tor v2 (if any) will be left untouched in the onion_private_key file in the data directory (see -datadir) and can be removed if not needed. Aixcoin Core will no longer attempt to read it. The private key for the Tor v3 service will be saved in a file named onion_v3_private_key. To use the deprecated Tor v2 service (not recommended), the onion_private_key can be copied over onion_v3_private_key, e.g. cp -f onion_private_key onion_v3_private_key. (#19954)
The client writes a file (anchors.dat) at shutdown with the network addresses of the node’s two outbound block-relay-only peers (so called “anchors”). The next time the node starts, it reads this file and attempts to reconnect to those same two peers. This prevents an attacker from using node restarts to trigger a complete change in peers, which would be something they could use as part of an eclipse attack. (#17428)
This release adds support for serving BIP157 compact filters to peers on the network when enabled using -blockfilterindex=1 -peerblockfilters=1. (#16442)
This release adds support for signets (BIP325) in addition to the existing mainnet, testnet, and regtest networks. Signets are centrally-controlled test networks, allowing them to be more predictable test environments than the older testnet. One public signet is maintained, and selectable using -signet. It is also possible to create personal signets. (#18267).
This release implements BIP339 wtxid relay. When negotiated, transactions are announced using their wtxid instead of their txid. (#18044).
This release implements the proposed Taproot consensus rules (BIP341 and BIP342), without activation on mainnet. Experimentation with Taproot can be done on signet, where its rules are already active. (#19553)

Updated RPCs

The getpeerinfo RPC has a new network field that provides the type of network (“ipv4”, “ipv6”, or “onion”) that the peer connected through. (#20002)
The getpeerinfo RPC now has additional last_block and last_transaction fields that return the UNIX epoch time of the last block and the last valid transaction received from each peer. (#19731)
getnetworkinfo now returns two new fields, connections_in and connections_out, that provide the number of inbound and outbound peer connections. These new fields are in addition to the existing connections field, which returns the total number of peer connections. (#19405)
Exposed transaction version numbers are now treated as unsigned 32-bit integers instead of signed 32-bit integers. This matches their treatment in consensus logic. Versions greater than 2 continue to be non-standard (matching previous behavior of smaller than 1 or greater than 2 being non-standard). Note that this includes the joinpsbt command, which combines partially-signed transactions by selecting the highest version number. (#16525)
getmempoolinfo now returns an additional unbroadcastcount field. The mempool tracks locally submitted transactions until their initial broadcast is acknowledged by a peer. This field returns the count of transactions waiting for acknowledgement.
Mempool RPCs such as getmempoolentry and getrawmempool with verbose=true now return an additional unbroadcast field. This indicates whether initial broadcast of the transaction has been acknowledged by a peer. getmempoolancestors and getmempooldescendants are also updated.
The getpeerinfo RPC no longer returns the banscore field unless the configuration option -deprecatedrpc=banscore is used. The banscore field will be fully removed in the next major release. (#19469)
The testmempoolaccept RPC returns vsize and a fees object with the base fee if the transaction would pass validation. (#19940)
The getpeerinfo RPC now returns a connection_type field. This indicates the type of connection established with the peer. It will return one of six options. For more information, see the getpeerinfo help documentation. (#19725)
The getpeerinfo RPC no longer returns the addnode field by default. This field will be fully removed in the next major release. It can be accessed with the configuration option -deprecatedrpc=getpeerinfo_addnode. However, it is recommended to instead use the connection_type field (it will return manual when addnode is true). (#19725)
The getpeerinfo RPC no longer returns the whitelisted field by default. This field will be fully removed in the next major release. It can be accessed with the configuration option -deprecatedrpc=getpeerinfo_whitelisted. However, it is recommended to instead use the permissions field to understand if specific privileges have been granted to the peer. (#19770)
The walletcreatefundedpsbt RPC call will now fail with Insufficient funds when inputs are manually selected but are not enough to cover the outputs and fee. Additional inputs can automatically be added through the new add_inputs option. (#16377)
The fundrawtransaction RPC now supports add_inputs option that when false prevents adding more inputs if necessary and consequently the RPC fails.

Changes to Wallet or GUI related RPCs can be found in the GUI or Wallet section below.

New RPCs

The getindexinfo RPC returns the actively running indices of the node, including their current sync status and height. It also accepts an index_name to specify returning the status of that index only. (#19550)

Build System

Updated settings

The same ZeroMQ notification (e.g. -zmqpubhashtx=address) can now be specified multiple times to publish the same notification to different ZeroMQ sockets. (#18309)
The -banscore configuration option, which modified the default threshold for disconnecting and discouraging misbehaving peers, has been removed as part of changes in 0.20.1 and in this release to the handling of misbehaving peers. Refer to “Changes regarding misbehaving peers” in the 0.20.1 release notes for details. (#19464)
The -debug=db logging category, which was deprecated in 0.20 and replaced by -debug=walletdb to distinguish it from coindb, has been removed. (#19202)
A download permission has been extracted from the noban permission. For compatibility, noban implies the download permission, but this may change in future releases. Refer to the help of the affected settings -whitebind and -whitelist for more details. (#19191)
Netmasks that contain 1-bits after 0-bits (the 1-bits are not contiguous on the left side, e.g. 255.0.255.255) are no longer accepted. They are invalid according to RFC 4632. Netmasks are used in the -rpcallowip and -whitelist configuration options and in the setban RPC. (#19628)
The -blocksonly setting now completely disables fee estimation. (#18766)

Changes to Wallet or GUI related settings can be found in the GUI or Wallet section below.

Tools and Utilities

A new aixcoin-cli -netinfo command provides a network peer connections dashboard that displays data from the getpeerinfo and getnetworkinfo RPCs in a human-readable format. An optional integer argument from 0 to 4 may be passed to see increasing levels of detail. (#19643)
A new aixcoin-cli -generate command, equivalent to RPC generatenewaddress followed by generatetoaddress, can generate blocks for command line testing purposes. This is a client-side version of the former generate RPC. See the help for details. (#19133)
The aixcoin-cli -getinfo command now displays the wallet name and balance for each of the loaded wallets when more than one is loaded (e.g. in multiwallet mode) and a wallet is not specified with -rpcwallet. (#18594)
The connections field of aixcoin-cli -getinfo is now expanded to return a JSON object with in, out and total numbers of peer connections. It previously returned a single integer value for the total number of peer connections. (#19405)

New settings

The startupnotify option is used to specify a command to execute when Aixcoin Core has finished with its startup sequence. (#15367)

Wallet

Backwards compatibility has been dropped for two getaddressinfo RPC deprecations, as notified in the 0.20 release notes. The deprecated label field has been removed as well as the deprecated labels behavior of returning a JSON object containing name and purpose key-value pairs. Since 0.20, the labels field returns a JSON array of label names. (#19200)
To improve wallet privacy, the frequency of wallet rebroadcast attempts is reduced from approximately once every 15 minutes to once every 12-36 hours. To maintain a similar level of guarantee for initial broadcast of wallet transactions, the mempool tracks these transactions as a part of the newly introduced unbroadcast set. See the “P2P and network changes” section for more information on the unbroadcast set. (#18038)
The sendtoaddress and sendmany RPCs accept an optional verbose=True argument to also return the fee reason about the sent tx. (#19501)
The wallet can create a transaction without change even when the keypool is empty. Previously it failed. (#17219)
The -salvagewallet startup option has been removed. A new salvage command has been added to the aixcoin-wallet tool which performs the salvage operations that -salvagewallet did. (#18918)
A new configuration flag -maxapsfee has been added, which sets the max allowed avoid partial spends (APS) fee. It defaults to 0 (i.e. fee is the same with and without APS). Setting it to -1 will disable APS, unless -avoidpartialspends is set. (#14582)
The wallet will now avoid partial spends (APS) by default, if this does not result in a difference in fees compared to the non-APS variant. The allowed fee threshold can be adjusted using the new -maxapsfee configuration option. (#14582)
The createwallet, loadwallet, and unloadwallet RPCs now accept load_on_startup options to modify the settings list. Unless these options are explicitly set to true or false, the list is not modified, so the RPC methods remain backwards compatible. (#15937)
A new send RPC with similar syntax to walletcreatefundedpsbt, including support for coin selection and a custom fee rate, is added. The send RPC is experimental and may change in subsequent releases. (#16378)
The estimate_mode parameter is now case-insensitive in the bumpfee, fundrawtransaction, sendmany, sendtoaddress, send and walletcreatefundedpsbt RPCs. (#11413)
The bumpfee RPC now uses conf_target rather than confTarget in the options. (#11413)
fundrawtransaction and walletcreatefundedpsbt when used with the lockUnspents argument now lock manually selected coins, in addition to automatically selected coins. Note that locked coins are never used in automatic coin selection, but can still be manually selected. (#18244)
The -zapwallettxes startup option has been removed and its functionality removed from the wallet. This option was originally intended to allow for rescuing wallets which were affected by a malleability attack. More recently, it has been used in the fee bumping of transactions that did not signal RBF. This functionality has been superseded with the abandon transaction feature. (#19671)
The error code when no wallet is loaded, but a wallet RPC is called, has been changed from -32601 (method not found) to -18 (wallet not found). (#20101)

Automatic wallet creation removed

Aixcoin Core will no longer automatically create new wallets on startup. It will load existing wallets specified by -wallet options on the command line or in aixcoin.conf or settings.json files. And by default it will also load a top-level unnamed (“”) wallet. However, if specified wallets don’t exist, Aixcoin Core will now just log warnings instead of creating new wallets with new keys and addresses like previous releases did.

New wallets can be created through the GUI (which has a more prominent create wallet option), through the aixcoin-cli createwallet or aixcoin-wallet create commands, or the createwallet RPC. (#15454, #20186)

Experimental Descriptor Wallets

Please note that Descriptor Wallets are still experimental and not all expected functionality is available. Additionally there may be some bugs and current functions may change in the future. Bugs and missing functionality can be reported to the issue tracker.

0.21 introduces a new type of wallet - Descriptor Wallets. Descriptor Wallets store scriptPubKey information using output descriptors. This is in contrast to the Legacy Wallet structure where keys are used to implicitly generate scriptPubKeys and addresses. Because of this shift to being script based instead of key based, many of the confusing things that Legacy Wallets do are not possible with Descriptor Wallets. Descriptor Wallets use a definition of “mine” for scripts which is simpler and more intuitive than that used by Legacy Wallets. Descriptor Wallets also uses different semantics for watch-only things and imports.

As Descriptor Wallets are a new type of wallet, their introduction does not affect existing wallets. Users who already have a Aixcoin Core wallet can continue to use it as they did before without any change in behavior. Newly created Legacy Wallets (which remains the default type of wallet) will behave as they did in previous versions of Aixcoin Core.

The differences between Descriptor Wallets and Legacy Wallets are largely limited to non user facing things. They are intended to behave similarly except for the import/export and watchonly functionality as described below.

Creating Descriptor Wallets

Descriptor wallets are not the default type of wallet.

In the GUI, a checkbox has been added to the Create Wallet Dialog to indicate that a Descriptor Wallet should be created. And a descriptors option has been added to createwallet RPC. Setting descriptors to true will create a Descriptor Wallet instead of a Legacy Wallet.

Without those options being set, a Legacy Wallet will be created instead.

`IsMine` Semantics

IsMine refers to the function used to determine whether a script belongs to the wallet. This is used to determine whether an output belongs to the wallet. IsMine in Legacy Wallets returns true if the wallet would be able to sign an input that spends an output with that script. Since keys can be involved in a variety of different scripts, this definition for IsMine can lead to many unexpected scripts being considered part of the wallet.

With Descriptor Wallets, descriptors explicitly specify the set of scripts that are owned by the wallet. Since descriptors are deterministic and easily enumerable, users will know exactly what scripts the wallet will consider to belong to it. Additionally the implementation of IsMine in Descriptor Wallets is far simpler than for Legacy Wallets. Notably, in Legacy Wallets, IsMine allowed for users to take one type of address (e.g. P2PKH), mutate it into another address type (e.g. P2WPKH), and the wallet would still detect outputs sending to the new address type even without that address being requested from the wallet. Descriptor Wallets do not allow for this and will only watch for the addresses that were explicitly requested from the wallet.

These changes to IsMine will make it easier to reason about what scripts the wallet will actually be watching for in outputs. However for the vast majority of users, this change is largely transparent and will not have noticeable effect.

Imports and Exports

In Legacy Wallets, raw scripts and keys could be imported to the wallet. Those imported scripts and keys are treated separately from the keys generated by the wallet. This complicates the IsMine logic as it has to distinguish between spendable and watchonly.

Descriptor Wallets handle importing scripts and keys differently. Only complete descriptors can be imported. These descriptors are then added to the wallet as if it were a descriptor generated by the wallet itself. This simplifies the IsMine logic so that it no longer has to distinguish between spendable and watchonly. As such, the watchonly model for Descriptor Wallets is also different and described in more detail in the next section.

To import into a Descriptor Wallet, a new importdescriptors RPC has been added that uses a syntax similar to that of importmulti.

As Legacy Wallets and Descriptor Wallets use different mechanisms for storing and importing scripts and keys the existing import RPCs have been disabled for descriptor wallets. New export RPCs for Descriptor Wallets have not yet been added.

The following RPCs are disabled for Descriptor Wallets:

importprivkey
importpubkey
importaddress
importwallet
dumpprivkey
dumpwallet
importmulti
addmultisigaddress
sethdseed

Watchonly Wallets

A Legacy Wallet contains both private keys and scripts that were being watched. Those watched scripts would not contribute to your normal balance. In order to see the watchonly balance and to use watchonly things in transactions, an include_watchonly option was added to many RPCs that would allow users to do that. However it is easy to forget to include this option.

Descriptor Wallets move to a per-wallet watchonly model. Instead an entire wallet is considered to be watchonly depending on whether it was created with private keys disabled. This eliminates the need to distinguish between things that are watchonly and things that are not within a wallet itself.

This change does have a caveat. If a Descriptor Wallet with private keys enabled has a multiple key descriptor without all of the private keys (e.g. multi(...) with only one private key), then the wallet will fail to sign and broadcast transactions. Such wallets would need to use the PSBT workflow but the typical GUI Send, sendtoaddress, etc. workflows would still be available, just non-functional.

This issue is worsened if the wallet contains both single key (e.g. wpkh(...)) descriptors and such multiple key descriptors as some transactions could be signed and broadcast and others not. This is due to some transactions containing only single key inputs, while others would contain both single key and multiple key inputs, depending on which are available and how the coin selection algorithm selects inputs. However this is not considered to be a supported use case; multisigs should be in their own wallets which do not already have descriptors. Although users cannot export descriptors with private keys for now as explained earlier.

BIP 44/49/84 Support

The change to using descriptors changes the default derivation paths used by Aixcoin Core to adhere to BIP 44/49/84. Descriptors with different derivation paths can be imported without issue.

SQLite Database Backend

Descriptor wallets use SQLite for the wallet file instead of the Berkeley DB used in legacy wallets. This will break compatibility with any existing tooling that operates on wallets, however compatibility was already being broken by the move to descriptors.

Wallet RPC changes

The upgradewallet RPC replaces the -upgradewallet command line option. (#15761)
The settxfee RPC will fail if the fee was set higher than the -maxtxfee command line setting. The wallet will already fail to create transactions with fees higher than -maxtxfee. (#18467)
A new fee_rate parameter/option denominated in satoshis per vbyte (sat/vB) is introduced to the sendtoaddress, sendmany, fundrawtransaction and walletcreatefundedpsbt RPCs as well as to the experimental new send RPC. The legacy feeRate option in fundrawtransaction and walletcreatefundedpsbt still exists for setting a fee rate in AIX per 1,000 vbytes (AIX/kvB), but it is expected to be deprecated soon to avoid confusion. For these RPCs, the fee rate error message is updated from AIX/kB to sat/vB and the help documentation in AIX/kB is updated to AIX/kvB. The send and sendtoaddress RPC examples are updated to aid users in creating transactions with explicit fee rates. (#20305, #11413)
The bumpfee RPC fee_rate option is changed from AIX/kvB to sat/vB and the help documentation is updated. Users are warned that this is a breaking API change, but it should be relatively benign: the large (100,000 times) difference between AIX/kvB and sat/vB units means that a transaction with a fee rate mistakenly calculated in AIX/kvB rather than sat/vB should raise an error due to the fee rate being set too low. In the worst case, the transaction may send at 1 sat/vB, but as Replace-by-Fee (BIP125 RBF) is active by default when an explicit fee rate is used, the transaction fee can be bumped. (#20305)

GUI changes

Wallets created or loaded in the GUI will now be automatically loaded on startup, so they don’t need to be manually reloaded next time Aixcoin Core is started. The list of wallets to load on startup is stored in \<datadir\>/settings.json and augments any command line or aixcoin.conf -wallet= settings that specify more wallets to load. Wallets that are unloaded in the GUI get removed from the settings list so they won’t load again automatically next startup. (#19754)
The GUI Peers window no longer displays a “Ban Score” field. This is part of changes in 0.20.1 and in this release to the handling of misbehaving peers. Refer to “Changes regarding misbehaving peers” in the 0.20.1 release notes for details. (#19512)

Low-level changes

RPC

To make RPC sendtoaddress more consistent with sendmany the following error sendtoaddress codes were changed from -4 to -6:
- Insufficient funds
- Fee estimation failed
- Transaction has too long of a mempool chain
The sendrawtransaction error code for exceeding maxfeerate has been changed from -26 to -25. The error string has been changed from “absurdly-high-fee” to “Fee exceeds maximum configured by user (e.g. -maxtxfee, maxfeerate).” The testmempoolaccept RPC returns max-fee-exceeded rather than absurdly-high-fee as the reject-reason. (#19339)
To make wallet and rawtransaction RPCs more consistent, the error message for exceeding maximum feerate has been changed to “Fee exceeds maximum configured by user (e.g. -maxtxfee, maxfeerate).” (#19339)

Tests

The BIP 325 default signet can be enabled by the -chain=signet or -signet setting. The settings -signetchallenge and -signetseednode allow enabling a custom signet.
The generateblock RPC allows testers using regtest mode to generate blocks that consist of a custom set of transactions. (#17693)

Aixcoin Core 0.20.2

Tue, 26 Oct 2021 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

0.20.2 Release Notes

Aixcoin Core version 0.20.2 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.20.2/

This minor release includes various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Compatibility

From Aixcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no longer supported. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

Known Bugs

The process for generating the source code release (“tarball”) has changed in an effort to make it more complete, however, there are a few regressions in this release:

The generated configure script is currently missing, and you will need to install autotools and run ./autogen.sh before you can run ./configure. This is the same as when checking out from git.
Instead of running make simply, you should instead run AIXCOIN_GENBUILD_NO_GIT=1 make.

Notable changes

Changes regarding misbehaving peers

Peers that misbehave (e.g. send us invalid blocks) are now referred to as discouraged nodes in log output, as they’re not (and weren’t) strictly banned: incoming connections are still allowed from them, but they’re preferred for eviction.

Furthermore, a few additional changes are introduced to how discouraged addresses are treated:

Discouraging an address does not time out automatically after 24 hours (or the -bantime setting). Depending on traffic from other peers, discouragement may time out at an indeterminate time.
Discouragement is not persisted over restarts.
There is no method to list discouraged addresses. They are not returned by the listbanned RPC. That RPC also no longer reports the ban_reason field, as "manually added" is the only remaining option.
Discouragement cannot be removed with the setban remove RPC command. If you need to remove a discouragement, you can remove all discouragements by stop-starting your node.

Notification changes

-walletnotify notifications are now sent for wallet transactions that are removed from the mempool because they conflict with a new block. These notifications were sent previously before the v0.19 release, but had been broken since that release (bug #18325).

PSBT changes

PSBTs will contain both the non-witness utxo and the witness utxo for segwit inputs in order to restore compatibility with wallet software that are now requiring the full previous transaction for segwit inputs. The witness utxo is still provided to maintain compatibility with software which relied on its existence to determine whether an input was segwit.

Instead of running make simply, you should instead run AIXCOIN_GENBUILD_NO_GIT=1 make.

Notable changes

P2P and network changes

Removal of BIP61 reject network messages from Aixcoin Core

The -enablebip61 command line option to enable BIP61 has been removed. (#17004)

This feature has been disabled by default since Aixcoin Core version 0.18.0. Nodes on the network can not generally be trusted to send valid messages (including reject messages), so this should only ever be used when connected to a trusted node. Please use the alternatives recommended below if you rely on this removed feature:

Testing or debugging of implementations of the Aixcoin P2P network protocol should be done by inspecting the log messages that are produced by a recent version of Aixcoin Core. Aixcoin Core logs debug messages (-debug=<category>) to a stream (-printtoconsole) or to a file (-debuglogfile=<debug.log>).
Testing the validity of a block can be achieved by specific RPCs:
- submitblock
- getblocktemplate with 'mode' set to 'proposal' for blocks with potentially invalid POW
Testing the validity of a transaction can be achieved by specific RPCs:
- sendrawtransaction
- testmempoolaccept
Wallets should not assume a transaction has propagated to the network just because there are no reject messages. Instead, listen for the transaction to be announced by other peers on the network. Wallets should not assume a lack of reject messages means a transaction pays an appropriate fee. Instead, set fees using fee estimation and use replace-by-fee to increase a transaction’s fee if it hasn’t confirmed within the desired amount of time.

The removal of BIP61 reject message support also has the following minor RPC and logging implications:

testmempoolaccept and sendrawtransaction no longer return the P2P reject code when a transaction is not accepted to the mempool. They still return the verbal reject reason.
Log messages that previously reported the reject code when a transaction was not accepted to the mempool now no longer report the reject code. The reason for rejection is still reported.

Updated RPCs

The RPCs which accept descriptors now accept the new sortedmulti(...) descriptor type which supports multisig scripts where the public keys are sorted lexicographically in the resulting script. (#17056)
The walletprocesspsbt and walletcreatefundedpsbt RPCs now include BIP32 derivation paths by default for public keys if we know them. This can be disabled by setting the bip32derivs parameter to false. (#17264)
The bumpfee RPC’s parameter totalFee, which was deprecated in 0.19, has been removed. (#18312)
The bumpfee RPC will return a PSBT when used with wallets that have private keys disabled. (#16373)
The getpeerinfo RPC now includes a mapped_as field to indicate the mapped Autonomous System used for diversifying peer selection. See the -asmap configuration option described below in New Settings. (#16702)
The createmultisig and addmultisigaddress RPCs now return an output script descriptor for the newly created address. (#18032)

Build System

OpenSSL is no longer used by Aixcoin Core. (#17265)
BIP70 support has been fully removed from Aixcoin Core. The --enable-bip70 option remains, but it will throw an error during configure. (#17165)
glibc 2.17 or greater is now required to run the release binaries. This retains compatibility with RHEL 7, CentOS 7, Debian 8 and Ubuntu 14.04 LTS. (#17538)
The source code archives that are provided with gitian builds no longer contain any autotools artifacts. Therefore, to build from such source, a user should run the ./autogen.sh script from the root of the unpacked archive. This implies that autotools and other required packages are installed on the user’s system. (#18331)

New settings

New rpcwhitelist and rpcwhitelistdefault configuration parameters allow giving certain RPC users permissions to only some RPC calls. (#12763)
A new -asmap configuration option has been added to diversify the node’s network connections by mapping IP addresses Autonomous System Numbers (ASNs) and then limiting the number of connections made to any single ASN. See issue #16599, PR #16702, and the aixcoind help for more information. This option is experimental and subject to removal or breaking changes in future releases, so the legacy /16 prefix mapping of IP addresses remains the default. (#16702)

Updated settings

All custom settings configured when Aixcoin Core starts are now written to the debug.log file to assist troubleshooting. (#16115)
Importing blocks upon startup via the bootstrap.dat file no longer occurs by default. The file must now be specified with -loadblock=<file>. (#17044)
The -debug=db logging category has been renamed to -debug=walletdb to distinguish it from coindb. The -debug=db option has been deprecated and will be removed in the next major release. (#17410)
The -walletnotify configuration parameter will now replace any %w in its argument with the name of the wallet generating the notification. This is not supported on Windows. (#13339)

Removed settings

The -whitelistforcerelay configuration parameter has been removed after it was discovered that it was rendered ineffective in version 0.13 and hasn’t actually been supported for almost four years. (#17985)

GUI changes

The “Start Aixcoin Core on system login” option has been removed on macOS. (#17567)
In the Peers window, the details for a peer now displays a Mapped AS field to indicate the mapped Autonomous System used for diversifying peer selection. See the -asmap configuration option in New Settings, above. (#18402)
A “known bug” announced in the release notes of version 0.18 has been fixed. The issue affected anyone who simultaneously used multiple Aixcoin Core wallets and the GUI coin control feature. (#18894)
For watch-only wallets, creating a new transaction in the Send screen or fee bumping an existing transaction in the Transactions screen will automatically copy a Partially-Signed Aixcoin Transaction (PSBT) to the system clipboard. This can then be pasted into an external program such as HWI for signing. Future versions of Aixcoin Core should support a GUI option for finalizing and broadcasting PSBTs, but for now the debug console may be used with the finalizepsbt and sendrawtransaction RPCs. (#16944, #17492)

Wallet

The wallet now by default uses bech32 addresses when using RPC, and creates native segwit change outputs. (#16884)
The way that output trust was computed has been fixed, which affects confirmed/unconfirmed balance status and coin selection. (#16766)
The gettransaction, listtransactions and listsinceblock RPC responses now also include the height of the block that contains the wallet transaction, if any. (#17437)
The getaddressinfo RPC has had its label field deprecated (re-enable for this release using the configuration parameter -deprecatedrpc=label). The labels field is altered from returning JSON objects to returning a JSON array of label names (re-enable previous behavior for this release using the configuration parameter -deprecatedrpc=labelspurpose). Backwards compatibility using the deprecated configuration parameters is expected to be dropped in the 0.21 release. (#17585, #17578)

Documentation changes

Aixcoin Core’s automatically-generated source code documentation is now available at https://doxygen.aixcoin-core.github.io. (#17596)

Low-level changes

Utilities

The aixcoin-cli utility used with the -getinfo parameter now returns a headers field with the number of downloaded block headers on the best headers chain (similar to the blocks field that is also returned) and a verificationprogress field that estimates how much of the best block chain has been synced by the local node. The information returned no longer includes the protocolversion, walletversion, and keypoololdest fields. (#17302, #17650)
The aixcoin-cli utility now accepts a -stdinwalletpassphrase parameter that can be used when calling the walletpassphrase and walletpassphrasechange RPCs to read the passphrase from standard input without echoing it to the terminal, improving security against anyone who can look at your screen. The existing -stdinrpcpass parameter is also updated to not echo the passphrase. (#13716)

Command line

Command line options prefixed with main/test/regtest network names like -main.port=8333 -test.server=1 previously were allowed but ignored. Now they trigger “Invalid parameter” errors on startup. (#17482)

New RPCs

The dumptxoutset RPC outputs a serialized snapshot of the current UTXO set. A script is provided in the contrib/devtools directory for generating a snapshot of the UTXO set at a particular block height. (#16899)
The generatetodescriptor RPC allows testers using regtest mode to generate blocks that pay an arbitrary output script descriptor. (#16943)

Updated RPCs

The verifychain RPC default values are now static instead of depending on the command line options or configuration file (-checklevel, and -checkblocks). Users can pass in the RPC arguments explicitly when they don’t want to rely on the default values. (#18541)
The getblockchaininfo RPC’s verificationprogress field will no longer report values higher than 1. Previously it would occasionally report the chain was more than 100% verified. (#17328)

Tests

It is now an error to use an unqualified walletdir=path setting in the config file if running on testnet or regtest networks. The setting now needs to be qualified as chain.walletdir=path or placed in the appropriate [chain] section. (#17447)
-fallbackfee was 0 (disabled) by default for the main chain, but 0.0002 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=0.0002 to their configuration if they weren’t setting it and they want it to keep working like before. (#16524)

Build system

Support is provided for building with the Android Native Development Kit (NDK). (#16110)

Aixcoin Core 0.19.1

Mon, 09 Mar 2020 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

0.19.1 Release Notes

Aixcoin Core version 0.19.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.19.1/

Download torrent

This minor release includes various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Aixcoin-Qt (on Mac) or aixcoind/aixcoin-qt (on Linux).

Upgrading directly from a version of Aixcoin Core that has reached its EOL is possible, but it might take some time if the datadir needs to be migrated. Old wallet versions of Aixcoin Core are generally supported.

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Aixcoin Core on unsupported systems.

Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

From Aixcoin Core 0.17.0 onwards, macOS versions earlier than 10.10 are no longer supported, as Aixcoin Core is now built using Qt 5.9.x which requires macOS 10.10+. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

In addition to previously supported CPU platforms, this release’s pre-compiled distribution provides binaries for the RISC-V platform.

Upgrading directly from a version of Aixcoin Core that has reached its EOL is possible, but might take some time if the datadir needs to be migrated. Old wallet versions of Aixcoin Core are generally supported.

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Aixcoin Core on unsupported systems.

Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

From 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10. Additionally, Aixcoin Core does not yet change appearance when macOS “dark mode” is activated.

Users running macOS Catalina may need to “right-click” and then choose “Open” to open the Aixcoin Core .dmg. This is due to new signing requirements imposed by Apple, which the Aixcoin Core project does not yet adhere too.

Notable changes

New user documentation

Reduce memory suggests configuration tweaks for running Aixcoin Core on systems with limited memory. (#16339)

New RPCs

getbalances returns an object with all balances (mine, untrusted_pending and immature). Please refer to the RPC help of getbalances for details. The new RPC is intended to replace getbalance, getunconfirmedbalance, and the balance fields in getwalletinfo. These old calls and fields may be removed in a future version. (#15930, #16239)
setwalletflag sets and unsets wallet flags that enable or disable features specific to that existing wallet, such as the new avoid_reuse feature documented elsewhere in these release notes. (#13756)
getblockfilter gets the BIP158 filter for the specified block. This RPC is only enabled if block filters have been created using the -blockfilterindex configuration option. (#14121)

New settings

-blockfilterindex enables the creation of BIP158 block filters for the entire blockchain. Filters will be created in the background and currently use about 4 GiB of space. Note: this version of Aixcoin Core does not serve block filters over the P2P network, although the local user may obtain block filters using the getblockfilter RPC. (#14121)

Updated settings

whitebind and whitelist now accept a list of permissions to provide peers connecting using the indicated interfaces or IP addresses. If no permissions are specified with an address or CIDR network, the implicit default permissions are the same as previous releases. See the aixcoind -help output for these two options for details about the available permissions. (#16248)
Users setting custom dbcache values can increase their setting slightly without using any more real memory. Recent changes reduced the memory use by about 9% and made chainstate accounting more accurate (it was underestimating the use of memory before). For example, if you set a value of “450” before, you may now set a value of “500” to use about the same real amount of memory. (#16957)

Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described in the Low-level Changes section below.

sendmany no longer has a minconf argument. This argument was not well-specified and would lead to RPC errors even when the wallet’s coin selection succeeded. Users who want to influence coin selection can use the existing -spendzeroconfchange, -limitancestorcount, -limitdescendantcount and -walletrejectlongchains configuration arguments. (#15596)
getbalance and sendtoaddress, plus the new RPCs getbalances and createwallet, now accept an “avoid_reuse” parameter that controls whether already used addresses should be included in the operation. Additionally, sendtoaddress will avoid partial spends when avoid_reuse is enabled even if this feature is not already enabled via the -avoidpartialspends command line flag because not doing so would risk using up the “wrong” UTXO for an address reuse case. (#13756)
RPCs which have an include_watchonly argument or includeWatching option now default to true for watch-only wallets. Affected RPCs are: getbalance, listreceivedbyaddress, listreceivedbylabel, listtransactions, listsinceblock, gettransaction, walletcreatefundedpsbt, and fundrawtransaction. (#16383)
listunspent now returns a “reused” bool for each output if the wallet flag “avoid_reuse” is enabled. (#13756)
getblockstats now uses BlockUndo data instead of the transaction index, making it much faster, no longer dependent on the -txindex configuration option, and functional for all non-pruned blocks. (#14802)
utxoupdatepsbt now accepts a descriptors parameter that will fill out input and output scripts and keys when known. P2SH-witness inputs will be filled in from the UTXO set when a descriptor is provided that shows they’re spending segwit outputs. See the RPC help text for full details. (#15427)
sendrawtransaction and testmempoolaccept no longer accept a allowhighfees parameter to fail mempool acceptance if the transaction fee exceeds the value of the configuration option -maxtxfee. Now there is a hardcoded default maximum feerate that can be changed when calling either RPC using a maxfeerate parameter. (#15620)
getmempoolancestors, getmempooldescendants, getmempoolentry, and getrawmempool no longer return a size field unless the configuration option -deprecatedrpc=size is used. Instead a new vsize field is returned with the transaction’s virtual size (consistent with other RPCs such as getrawtransaction). (#15637)
getwalletinfo now includes a scanning field that is either false (no scanning) or an object with information about the duration and progress of the wallet’s scanning historical blocks for transactions affecting its balances. (#15730)
gettransaction now accepts a third (boolean) argument verbose. If set to true, a new decoded field will be added to the response containing the decoded transaction. This field is equivalent to RPC decoderawtransaction, or RPC getrawtransaction when verbose is passed. (#16185, #16866, #16873)
createwallet accepts a new passphrase parameter. If set, this will create the new wallet encrypted with the given passphrase. If unset (the default) or set to an empty string, no encryption will be used. (#16394)
getchaintxstats RPC now returns the additional key of window_final_block_height. (#16695)
getmempoolentry now provides a weight field containing the transaction weight as defined in BIP141. (#16647)
The getnetworkinfo and getpeerinfo commands now contain a new field with decoded network service flags. (#16786)
getdescriptorinfo now returns an additional checksum field containing the checksum for the unmodified descriptor provided by the user (that is, before the descriptor is normalized for the descriptor field). (#15986)
joinpsbts now shuffles the order of the inputs and outputs of the resulting joined PSBT. Previously, inputs and outputs were added in the order PSBTs were provided. This made it easy to correlate inputs to outputs, representing a privacy leak. (#16512)
walletcreatefundedpsbt now signals BIP125 Replace-by-Fee if the -walletrbf configuration option is set to true. (#15911)

GUI changes

The GUI wallet now provides bech32 addresses by default. The user may change the address type during invoice generation using a GUI toggle, or the default address type may be changed with the -addresstype configuration option. (#15711, #16497)
In 0.18.0, a ./configure flag was introduced to allow disabling BIP70 support in the GUI (support was enabled by default). In 0.19.0, this flag is now disabled by default. If you want to compile Aixcoin Core with BIP70 support in the GUI, you can pass --enable-bip70 to ./configure. (#15584)

Deprecated or removed configuration options

-mempoolreplacement is removed, although default node behavior remains the same. This option previously allowed the user to prevent the node from accepting or relaying BIP125 transaction replacements. This is different from the remaining configuration option -walletrbf. (#16171)

Deprecated or removed RPCs

bumpfee no longer accepts a totalFee option unless the configuration parameter deprecatedrpc=totalFee is specified. This parameter will be fully removed in a subsequent release. (#15996)
bumpfee has a new fee_rate option as a replacement for the deprecated totalFee. (#16727)
generate is now removed after being deprecated in Aixcoin Core 0.18. Use the generatetoaddress RPC instead. (#15492)

P2P changes

BIP 61 reject messages were deprecated in v0.18. They are now disabled by default, but can be enabled by setting the -enablebip61 command line option. BIP 61 reject messages will be removed entirely in a future version of Aixcoin Core. (#14054)
To eliminate well-known denial-of-service vectors in Aixcoin Core, especially for nodes with spinning disks, the default value for the -peerbloomfilters configuration option has been changed to false. This prevents Aixcoin Core from sending the BIP111 NODE_BLOOM service flag, accepting BIP37 bloom filters, or serving merkle blocks or transactions matching a bloom filter. Users who still want to provide bloom filter support may either set the configuration option to true to re-enable both BIP111 and BIP37 support or enable just BIP37 support for specific peers using the updated -whitelist and -whitebind configuration options described elsewhere in these release notes. For the near future, lightweight clients using public BIP111/BIP37 nodes should still be able to connect to older versions of Aixcoin Core and nodes that have manually enabled BIP37 support, but developers of such software should consider migrating to either using specific BIP37 nodes or an alternative transaction filtering system. (#16152)
By default, Aixcoin Core will now make two additional outbound connections that are exclusively used for block-relay. No transactions or addr messages will be processed on these connections. These connections are designed to add little additional memory or bandwidth resource requirements but should make some partitioning attacks more difficult to carry out. (#15759)

Miscellaneous CLI Changes

The testnet field in aixcoin-cli -getinfo has been renamed to chain and now returns the current network name as defined in BIP70 (main, test, regtest). (#15566)

Low-level changes

RPC

getblockchaininfo no longer returns a bip9_softforks object. Instead, information has been moved into the softforks object and an additional type field describes how Aixcoin Core determines whether that soft fork is active (e.g. BIP9 or BIP90). See the RPC help for details. (#16060)
getblocktemplate no longer returns a rules array containing CSV and segwit (the BIP9 deployments that are currently in active state). (#16060)
getrpcinfo now returns a logpath field with the path to debug.log. (#15483)

Tests

The regression test chain enabled by the -regtest command line flag now requires transactions to not violate standard policy by default. This is the same default used for mainnet and makes it easier to test mainnet behavior on regtest. Note that the testnet still allows non-standard txs by default and that the policy can be locally adjusted with the -acceptnonstdtxn command line flag for both test chains. (#15891)

Configuration

A setting specified in the default section but not also specified in a network-specific section (e.g. testnet) will now produce an error preventing startup instead of just a warning unless the network is mainnet. This prevents settings intended for mainnet from being applied to testnet or regtest. (#15629)
On platforms supporting thread_local, log lines can be prefixed with the name of the thread that caused the log. To enable this behavior, use -logthreadnames=1. (#15849)

Network

When fetching a transaction announced by multiple peers, previous versions of Aixcoin Core would sequentially attempt to download the transaction from each announcing peer until the transaction is received, in the order that those peers’ announcements were received. In this release, the download logic has changed to randomize the fetch order across peers and to prefer sending download requests to outbound peers over inbound peers. This fixes an issue where inbound peers could prevent a node from getting a transaction. (#14897, #15834)
If a Tor hidden service is being used, Aixcoin Core will be bound to the standard port 8333 even if a different port is configured for clearnet connections. This prevents leaking node identity through use of identical non-default port numbers. (#15651)

Mempool and transaction relay

Allows one extra single-ancestor transaction per package. Previously, if a transaction in the mempool had 25 descendants, or it and all of its descendants were over 101,000 vbytes, any newly-received transaction that was also a descendant would be ignored. Now, one extra descendant will be allowed provided it is an immediate descendant (child) and the child’s size is 10,000 vbytes or less. This makes it possible for two-party contract protocols such as Lightning Network to give each participant an output they can spend immediately for Child-Pays-For-Parent (CPFP) fee bumping without allowing one malicious participant to fill the entire package and thus prevent the other participant from spending their output. (#15681)
Transactions with outputs paying v1 to v16 witness versions (future segwit versions) are now accepted into the mempool, relayed, and mined. Attempting to spend those outputs remains forbidden by policy (“non-standard”). When this change has been widely deployed, wallets and services can accept any valid bech32 Aixcoin address without concern that transactions paying future segwit versions will become stuck in an unconfirmed state. (#15846)
Legacy transactions (transactions with no segwit inputs) must now be sent using the legacy encoding format, enforcing the rule specified in BIP144. (#14039)

Wallet

When in pruned mode, a rescan that was triggered by an importwallet, importpubkey, importaddress, or importprivkey RPC will only fail when blocks have been pruned. Previously it would fail when -prune has been set. This change allows setting -prune to a high value (e.g. the disk size) without the calls to any of the import RPCs failing until the first block is pruned. (#15870)
When creating a transaction with a fee above -maxtxfee (default 0.1 AIX), the RPC commands walletcreatefundedpsbt and fundrawtransaction will now fail instead of rounding down the fee. Be aware that the feeRate argument is specified in AIX per 1,000 vbytes, not satoshi per vbyte. (#16257)
A new wallet flag avoid_reuse has been added (default off). When enabled, a wallet will distinguish between used and unused addresses, and default to not use the former in coin selection. When setting this flag on an existing wallet, rescanning the blockchain is required to correctly mark previously used destinations. Together with “avoid partial spends” (added in Aixcoin Core v0.17.0), this can eliminate a serious privacy issue where a malicious user can track spends by sending small payments to a previously-paid address that would then be included with unrelated inputs in future payments. (#13756)

Build system changes

Python >=3.5 is now required by all aspects of the project. This includes the build systems, test framework and linters. The previously supported minimum (3.4), was EOL in March 2019. (#14954)
The minimum supported miniUPnPc API version is set to 10. This keeps compatibility with Ubuntu 16.04 LTS and Debian 8 libminiupnpc-dev packages. Please note, on Debian this package is still vulnerable to CVE-2017-8798 (in jessie only) and CVE-2017-1000494 (both in jessie and in stretch). (#15993)

Aixcoin Core 0.18.1

Thu, 09 Aug 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.18.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.18.1/

Download torrent

This is a new minor version release, including new features, various bug fixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

The first time you run version 0.15.0 or newer, your chainstate database will be converted to a new format, which will take anywhere from a few minutes to half an hour, depending on the speed of your machine.

Note that the block database format also changed in version 0.8.0 and there is no automatic upgrade code from before version 0.8 to version 0.15.0 or later. Upgrading directly from 0.7.x and earlier without redownloading the blockchain is not supported. However, as usual, old wallet versions are still supported.

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Aixcoin Core on unsupported systems.

Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

Known issues

Wallet GUI

For advanced users who have both (1) enabled coin control features, and (2) are using multiple wallets loaded at the same time: The coin control input selection dialog can erroneously retain wrong-wallet state when switching wallets using the dropdown menu. For now, it is recommended not to use coin control features with multiple wallets loaded.

Aixcoin Core 0.18.0

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.18.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.18.0/

How to Upgrade

Compatibility

Aixcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Aixcoin Core on unsupported systems.

Aixcoin Core should also work on most other Unix-like systems but is not as frequently tested on them.

In addition to previously-supported CPU platforms, this release’s pre-compiled distribution also provides binaries for the RISC-V platform.

If you are using the systemd unit configuration file located at contrib/init/aixcoind.service, it has been changed to use /var/lib/aixcoind as the data directory instead of ~aixcoin/.aixcoin. When switching over to the new configuration file, please make sure that the filesystem on which /var/lib/aixcoind will exist has enough space (check using df -h /var/lib/aixcoind), and optionally copy over your existing data directory. See the systemd init file section for more details.

Known issues

Wallet GUI

Notable changes

Mining

Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.

Configuration option changes

A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the “high water mark”) before dropping additional messages. The default value is 1,000, the same as was used for previous releases. See the ZMQ documentation for details.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:8332:8332 (this is an extra :8332 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it’s ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers. Users can still explicitly enable this behavior with the command line option (and may want to consider contacting the Aixcoin Core project to let us know about their use-case, as this feature could be deprecated in the future).

systemd init file

The systemd init file (contrib/init/aixcoind.service) has been changed to use /var/lib/aixcoind as the data directory instead of ~aixcoin/.aixcoin. This change makes Aixcoin Core more consistent with other services, and makes the systemd init config more consistent with existing Upstart and OpenRC configs.

The configuration, PID, and data directories are now completely managed by systemd, which will take care of their creation, permissions, etc. See systemd.exec(5) for more details.

When using the provided init files under contrib/init, overriding the datadir option in /etc/aixcoin/aixcoin.conf will have no effect. This is because the command line arguments specified in the init files take precedence over the options specified in /etc/aixcoin/aixcoin.conf.

Documentation

A new short document about the JSON-RPC interface describes cases where the results of an RPC might contain inconsistencies between data sourced from different subsystems, such as wallet state and mempool state. A note is added to the REST interface documentation indicating that the same rules apply.
Further information is added to the JSON-RPC documentation about how to secure this interface.
A new document about the aixcoin.conf file describes how to use it to configure Aixcoin Core.
A new document introduces Aixcoin Core’s BIP174 Partially-Signed Aixcoin Transactions (PSBT) interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.

Build system changes

A new --disable-bip70 option may be passed to ./configure to prevent Aixcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Aixcoin Core to libssl vulnerabilities in the past, builders who don’t need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)

New RPCs

getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured by the -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. At the moment, it returns an array of the currently active commands and how long they’ve been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information about it, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all of the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyzepsbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.

Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described in the Low-level Changes section below.

getpeerinfo now returns an additional minfeefilter field set to the peer’s BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional “bip125-replaceable” value indicating whether the transaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of “0” may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable boolean field when Aixcoin Core knows enough about the address’s scriptPubKey, optional redeemScript, and optional witnessScript in order for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label “cold wallet” in earlier releases of Aixcoin Core, subsequently importing the private key would default to resetting the address’s label to the default empty-string label (“”). In this release, the previous label of “cold wallet” will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
See the Mining section for changes to getblocktemplate.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows: 1. If a blockhash is provided, check the corresponding block. 2. If no blockhash is provided, check the mempool. 3. If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A “desc” parameter can be provided instead of the “scriptPubKey” in a request, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs. More information about descriptors can be found here.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH or P2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HD seed. They cannot be opened in software older than 0.18. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 0.17.x. Encrypting a blank wallet will also set a HD seed for it.

Deprecated or removed RPCs

signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 0.17.0.
The ‘account’ API is removed after being deprecated in v0.17. The ‘label’ API was introduced in v0.17 as a replacement for accounts. See the release notes from v0.17 for a full description of the changes from the ‘account’ API to the ‘label’ API.
addwitnessaddress is removed after being deprecated in version 0.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart aixcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly, script, hex, pubkeys, sigsrequired, pubkey, embedded, iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddress and getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.

REST changes

A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).

Graphical User Interface (GUI)

A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for “pay only the required fee” has been removed. Instead, the user can simply decrease the value in the Custom Feerate field all the way down to the node’s configured minimum relay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and the disable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (use CXXFLAGS=”-mmacosx-version-min=10.11” CFLAGS=”-mmacosx-version-min=10.11” for setting the deployment sdk version)

Tools

A new aixcoin-wallet tool is now distributed alongside Aixcoin Core’s other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.

Planned changes

This section describes planned changes to Aixcoin Core that may affect other Aixcoin software and services.

Since version 0.16.0, Aixcoin Core’s built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely-used software. Starting with Aixcoin Core 0.20 (expected about a year after 0.18), Aixcoin Core will default to native segwit addresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Aixcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Aixcoin Core 0.19 (approximately November 2019). P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn’t want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Aixcoin Core release from 0.16.0 up.)

Deprecated P2P messages

BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v0.17 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.

Low-level changes

This section describes RPC changes mainly useful for testing, mostly not relevant in production. The changes are mentioned for completeness.

RPC

The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block, but returned a generic “duplicate” rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns “duplicate” for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH or P2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if the bip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).

Configuration

The -usehd configuration option was removed in version 0.16. From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.

Network

This release allows peers that your node automatically disconnected for misbehavior (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don’t have many other peers). Previously, Aixcoin Core banned the IP addresses of misbehaving peers for a period of time (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.

Wallet

The key metadata will need to be upgraded the first time that the HD seed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Aixcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Aixcoin Core. See their project page for details.

Security

This release changes the Random Number Generator (RNG) used from OpenSSL to Aixcoin Core’s own implementation, although entropy gathered by Aixcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Aixcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.

Changes for particular platforms

On macOS, Aixcoin Core now opts out of application CPU throttling (“app nap”) during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.

Aixcoin Core 0.17.1

Tue, 25 Dec 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.17.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.17.1/

Download torrent

This is a new minor version release, with various bugfixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

If your node has a txindex, the txindex db will be migrated the first time you run 0.17.0 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.

Note that the block database format also changed in version 0.8.0 and there is no automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading directly from 0.7.x and earlier without redownloading the blockchain is not supported. However, as usual, old wallet versions are still supported.

Downgrading warning

The chainstate database for this release is not compatible with previous releases, so if you run 0.15 and then decide to switch back to any older version, you will need to run the old release with the -reindex-chainstate option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not supported).

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.0 onwards macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10.

Notable changes

`listtransactions` label support

The listtransactions RPC account parameter which was deprecated in 0.17.0 and renamed to dummy has been un-deprecated and renamed again to label.

When aixcoin is configured with the -deprecatedrpc=accounts setting, specifying a label/account/dummy argument will return both outgoing and incoming transactions. Without the -deprecatedrpc=accounts setting, it will only return incoming transactions (because it used to be possible to create transactions spending from specific accounts, but this is no longer possible with labels).

When -deprecatedrpc=accounts is set, it’s possible to pass the empty string “” to list transactions that don’t have any label. Without -deprecatedrpc=accounts, passing the empty string is an error because returning only non-labeled transactions is not generally useful behavior and can cause confusion.

Aixcoin Core 0.17.0

Wed, 03 Oct 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.17.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.17.0/

How to Upgrade

If your node has a txindex, the txindex db will be migrated the first time you run 0.17.0 or newer, which may take up to a few hours. Your node will not be functional until this migration completes.

Downgrading warning

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer (Windows XP is not supported).

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.0 onwards macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn’t support versions of macOS older than 10.10.

Known issues

Upgrading from 0.13.0 or older currently results in memory blow-up during the roll-back of blocks to the SegWit activation point. In these cases, a full -reindex is necessary.
The GUI suffers from visual glitches in the new MacOS dark mode. This has to do with our Qt theme handling and is not a new problem in 0.17.0, but is expected to be resolved in 0.17.1.

Notable changes

Changed configuration options

-includeconf=<file> can be used to include additional configuration files. Only works inside the aixcoin.conf file, not inside included files or from command-line. Multiple files may be included. Can be disabled from command- line via -noincludeconf. Note that multi-argument commands like -includeconf will override preceding -noincludeconf, i.e.
```
noincludeconf=1
includeconf=relative.conf
```
as aixcoin.conf will still include relative.conf.

GUI changes

Block storage can be limited under Preferences, in the Main tab. Undoing this setting requires downloading the full blockchain again. This mode is incompatible with -txindex and -rescan.

External wallet files

The -wallet=<path> option now accepts full paths instead of requiring wallets to be located in the -walletdir directory.

Newly created wallet format

If -wallet=<path> is specified with a path that does not exist, it will now create a wallet directory at the specified location (containing a wallet.dat data file, a db.log file, and database/log.?????????? files) instead of just creating a data file at the path and storing log files in the parent directory. This should make backing up wallets more straightforward than before because the specified wallet path can just be directly archived without having to look in the parent directory for transaction log files.

For backwards compatibility, wallet paths that are names of existing data files in the -walletdir directory will continue to be accepted and interpreted the same as before.

Dynamic loading and creation of wallets

Previously, wallets could only be loaded or created at startup, by specifying -wallet parameters on the command line or in the aixcoin.conf file. It is now possible to load, create and unload wallets dynamically at runtime:

Existing wallets can be loaded by calling the loadwallet RPC. The wallet can be specified as file/directory basename (which must be located in the walletdir directory), or as an absolute path to a file/directory.
New wallets can be created (and loaded) by calling the createwallet RPC. The provided name must not match a wallet file in the walletdir directory or the name of a wallet that is currently loaded.
Loaded wallets can be unloaded by calling the unloadwallet RPC.

This feature is currently only available through the RPC interface.

Coin selection

Partial spend avoidance

When an address is paid multiple times the coins from those separate payments can be spent separately which hurts privacy due to linking otherwise separate addresses. A new -avoidpartialspends flag has been added (default=false). If enabled, the wallet will always spend existing UTXO to the same address together even if it results in higher fees. If someone were to send coins to an address after it was used, those coins will still be included in future coin selections.

Configuration sections for testnet and regtest

It is now possible for a single configuration file to set different options for different networks. This is done by using sections or by prefixing the option with the network, such as:

main.uacomment=aixcoin
test.uacomment=aixcoin-testnet
regtest.uacomment=regtest
[main]
mempoolsize=300
[test]
mempoolsize=100
[regtest]
mempoolsize=20

If the following options are not in a section, they will only apply to mainnet: addnode=, connect=, port=, bind=, rpcport=, rpcbind= and wallet=. The options to choose a network (regtest= and testnet=) must be specified outside of sections.

‘label’ and ‘account’ APIs for wallet

A new ‘label’ API has been introduced for the wallet. This is intended as a replacement for the deprecated ‘account’ API. The ‘account’ can continue to be used in V0.17 by starting aixcoind with the ‘-deprecatedrpc=accounts’ argument, and will be fully removed in V0.18.

The label RPC methods mirror the account functionality, with the following functional differences:

Labels can be set on any address, not just receiving addresses. This functionality was previously only available through the GUI.
Labels can be deleted by reassigning all addresses using the setlabel RPC method.
There isn’t support for sending transactions from a label, or for determining which label a transaction was sent from.
Labels do not have a balance.

Here are the changes to RPC methods:

Deprecated Method	New Method	Notes
`getaccount`	`getaddressinfo`	`getaddressinfo` returns a json object with address information instead of just the name of the account as a string.
`getaccountaddress`	n/a	There is no replacement for `getaccountaddress` since labels do not have an associated receive address.
`getaddressesbyaccount`	`getaddressesbylabel`	`getaddressesbylabel` returns a json object with the addresses as keys, instead of a list of strings.
`getreceivedbyaccount`	`getreceivedbylabel`	no change in behavior
`listaccounts`	`listlabels`	`listlabels` does not return a balance or accept `minconf` and `watchonly` arguments.
`listreceivedbyaccount`	`listreceivedbylabel`	Both methods return new `label` fields, along with `account` fields for backward compatibility.
`move`	n/a	no replacement
`sendfrom`	n/a	no replacement
`setaccount`	`setlabel`	Both methods now: • allow assigning labels to any address, instead of raising an error if the address is not receiving address. • delete the previous label associated with an address when the final address using that label is reassigned to a different label, instead of making an implicit `getaccountaddress` call to ensure the previous label still has a receiving address.

Changed Method	Notes
`addmultisigaddress`	Renamed `account` named parameter to `label`. Still accepts `account` for backward compatibility if running with ‘-deprecatedrpc=accounts’.
`getnewaddress`	Renamed `account` named parameter to `label`. Still accepts `account` for backward compatibility. if running with ‘-deprecatedrpc=accounts’
`listunspent`	Returns new `label` fields. `account` field will be returned for backward compatibility if running with ‘-deprecatedrpc=accounts’
`sendmany`	The `account` named parameter has been renamed to `dummy`. If provided, the `dummy` parameter must be set to the empty string, unless running with the `-deprecatedrpc=accounts` argument (in which case functionality is unchanged).
`listtransactions`	The `account` named parameter has been renamed to `dummy`. If provided, the `dummy` parameter must be set to the string `*`, unless running with the `-deprecatedrpc=accounts` argument (in which case functionality is unchanged).
`getbalance`	`account`, `minconf` and `include_watchonly` parameters are deprecated, and can only be used if running with ‘-deprecatedrpc=accounts’

BIP 174 Partially Signed Aixcoin Transactions support

BIP 174 PSBT is an interchange format for Aixcoin transactions that are not fully signed yet, together with relevant metadata to help entities work towards signing it. It is intended to simplify workflows where multiple parties need to cooperate to produce a transaction. Examples include hardware wallets, multisig setups, and CoinJoin transactions.

Overall workflow

Overall, the construction of a fully signed Aixcoin transaction goes through the following steps:

A Creator proposes a particular transaction to be created. He constructs a PSBT that contains certain inputs and outputs, but no additional metadata.
For each input, an Updater adds information about the UTXOs being spent by the transaction to the PSBT.
A potentially other Updater adds information about the scripts and public keys involved in each of the inputs (and possibly outputs) of the PSBT.
Signers inspect the transaction and its metadata to decide whether they agree with the transaction. They can use amount information from the UTXOs to assess the values and fees involved. If they agree, they produce a partial signature for the inputs for which they have relevant key(s).
A Finalizer is run for each input to convert the partial signatures and possibly script information into a final scriptSig and/or scriptWitness.
An Extractor produces a valid Aixcoin transaction (in network format) from a PSBT for which all inputs are finalized.

Generally, each of the above (excluding Creator and Extractor) will simply add more and more data to a particular PSBT. In a naive workflow, they all have to operate sequentially, passing the PSBT from one to the next, until the Extractor can convert it to a real transaction. In order to permit parallel operation, Combiners can be employed which merge metadata from different PSBTs for the same unsigned transaction.

The names above in bold are the names of the roles defined in BIP174. They’re useful in understanding the underlying steps, but in practice, software and hardware implementations will typically implement multiple roles simultaneously.

RPCs

converttopsbt (Creator) is a utility RPC that converts an unsigned raw transaction to PSBT format. It ignores existing signatures.
createpsbt (Creator) is a utility RPC that takes a list of inputs and outputs and converts them to a PSBT with no additional information. It is equivalent to calling createrawtransaction followed by converttopsbt.
walletcreatefundedpsbt (Creator, Updater) is a wallet RPC that creates a PSBT with the specified inputs and outputs, adds additional inputs and change to it to balance it out, and adds relevant metadata. In particular, for inputs that the wallet knows about (counting towards its normal or watch-only balance), UTXO information will be added. For outputs and inputs with UTXO information present, key and script information will be added which the wallet knows about. It is equivalent to running createrawtransaction, followed by fundrawtransaction, and converttopsbt.
walletprocesspsbt (Updater, Signer, Finalizer) is a wallet RPC that takes as input a PSBT, adds UTXO, key, and script data to inputs and outputs that miss it, and optionally signs inputs. Where possible it also finalizes the partial signatures.
finalizepsbt (Finalizer, Extractor) is a utility RPC that finalizes any partial signatures, and if all inputs are finalized, converts the result to a fully signed transaction which can be broadcast with sendrawtransaction.
combinepsbt (Combiner) is a utility RPC that implements a Combiner. It can be used at any point in the workflow to merge information added to different versions of the same PSBT. In particular it is useful to combine the output of multiple Updaters or Signers.
decodepsbt is a diagnostic utility RPC which will show all information in a PSBT in human-readable form, as well as compute its eventual fee if known.

Upgrading non-HD wallets to HD wallets

Since Aixcoin Core 0.13.0, creating new BIP 32 Hierarchical Deterministic wallets has been supported by Aixcoin Core but old non-HD wallets could not be upgraded to HD. Now non-HD wallets can be upgraded to HD using the -upgradewallet command line option. This upgrade will result in the all keys in the keypool being marked as used and a new keypool generated. A new backup must be made when this upgrade is performed.

Additionally, -upgradewallet can be used to upgraded from a non-split HD chain (all keys generated with m/0'/0'/i') to a split HD chain (receiving keys generated with 'm/0'/0'/i' and change keys generated with m'/0'/1'/i'). When this upgrade occurs, all keys already in the keypool will remain in the keypool to be used until all keys from before the upgrade are exhausted. This is to avoid issues with backups and downgrades when some keys may come from the change key keypool. Users can begin using the new split HD chain keypools by using the newkeypool RPC to mark all keys in the keypool as used and begin using a new keypool generated from the split HD chain.

HD Master key rotation

A new RPC, sethdseed, has been introduced which allows users to set a new HD seed or set their own HD seed. This allows for a new HD seed to be used. A new backup must be made when a new HD seed is set.

Low-level RPC changes

The new RPC scantxoutset can be used to scan the UTXO set for entries that match certain output descriptors. Refer to the output descriptors reference documentation for more details. This call is similar to listunspent but does not use a wallet, meaning that the wallet can be disabled at compile or run time. This call is experimental, as such, is subject to changes or removal in future releases.
The createrawtransaction RPC will now accept an array or dictionary (kept for compatibility) for the outputs parameter. This means the order of transaction outputs can be specified by the client.
The fundrawtransaction RPC will reject the previously deprecated reserveChangeKey option.
sendmany now shuffles outputs to improve privacy, so any previously expected behavior with regards to output ordering can no longer be relied upon.
The new RPC testmempoolaccept can be used to test acceptance of a transaction to the mempool without adding it.
JSON transaction decomposition now includes a weight field which provides the transaction’s exact weight. This is included in REST /rest/tx/ and /rest/block/ endpoints when in json mode. This is also included in getblock (with verbosity=2), listsinceblock, listtransactions, and getrawtransaction RPC commands.
New fees field introduced in getrawmempool, getmempoolancestors, getmempooldescendants and getmempoolentry when verbosity is set to true with sub-fields ancestor, base, modified and descendant denominated in AIX. This new field deprecates previous fee fields, such as fee, modifiedfee, ancestorfee and descendantfee.
The new RPC getzmqnotifications returns information about active ZMQ notifications.
When aixcoin is not started with any -wallet=<path> options, the name of the default wallet returned by getwalletinfo and listwallets RPCs is now the empty string "" instead of "wallet.dat". If aixcoin is started with any -wallet=<path> options, there is no change in behavior, and the name of any wallet is just its <path> string.
Passing an empty string ("") as the address_type parameter to getnewaddress, getrawchangeaddress, addmultisigaddress, fundrawtransaction RPCs is now an error. Previously, this would fall back to using the default address type. It is still possible to pass null or leave the parameter unset to use the default address type.
Bare multisig outputs to our keys are no longer automatically treated as incoming payments. As this feature was only available for multisig outputs for which you had all private keys in your wallet, there was generally no use for them compared to single-key schemes. Furthermore, no address format for such outputs is defined, and wallet software can’t easily send to it. These outputs will no longer show up in listtransactions, listunspent, or contribute to your balance, unless they are explicitly watched (using importaddress or importmulti with hex script argument). signrawtransaction* also still works for them.
The getwalletinfo RPC method now returns an hdseedid value, which is always the same as the incorrectly-named hdmasterkeyid value. hdmasterkeyid will be removed in V0.18.
The getaddressinfo RPC method now returns an hdseedid value, which is always the same as the incorrectly-named hdmasterkeyid value. hdmasterkeyid will be removed in V0.18.
Parts of the validateaddress RPC method have been deprecated and moved to getaddressinfo. Clients must transition to using getaddressinfo to access this information before upgrading to v0.18. The following deprecated fields have moved to getaddressinfo and will only be shown with -deprecatedrpc=validateaddress: ismine, iswatchonly, script, hex, pubkeys, sigsrequired, pubkey, addresses, embedded, iscompressed, account, timestamp, hdkeypath, hdmasterkeyid.
signrawtransaction is deprecated and will be fully removed in v0.18. To use signrawtransaction in v0.17, restart aixcoind with -deprecatedrpc=signrawtransaction. Projects should transition to using signrawtransactionwithkey and signrawtransactionwithwallet before upgrading to v0.18.

Other API changes

The inactivehdmaster property in the dumpwallet output has been corrected to inactivehdseed

Logging

The log timestamp format is now ISO 8601 (e.g. “2018-02-28T12:34:56Z”).
When running aixcoind with -debug but without -daemon, logging to stdout is now the default behavior. Setting -printtoconsole=1 no longer implicitly disables logging to debug.log. Instead, logging to file can be explicitly disabled by setting -debuglogfile=0.

Transaction index changes

The transaction index is now built separately from the main node procedure, meaning the -txindex flag can be toggled without a full reindex. If aixcoind is run with -txindex on a node that is already partially or fully synced without one, the transaction index will be built in the background and become available once caught up. When switching from running -txindex to running without the flag, the transaction index database will not be deleted automatically, meaning it could be turned back on at a later time without a full resync.

Miner block size removed

The -blockmaxsize option for miners to limit their blocks’ sizes was deprecated in V0.15.1, and has now been removed. Miners should use the -blockmaxweight option if they want to limit the weight of their blocks.

Python Support

Support for Python 2 has been discontinued for all test files and tools.

Aixcoin Core 0.16.3

Tue, 18 Sep 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.16.3 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.16.3/

This is a new minor version release, with various bugfixes as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

Note that the block database format also changed in version 0.8.0 and there is no automatic upgrade code from before version 0.8 to version 0.15.0 or higher. Upgrading directly from 0.7.x and earlier without re-downloading the blockchain is not supported. However, as usual, old wallet versions are still supported.

Downgrading warning

Wallets created in 0.16 and later are not compatible with versions prior to 0.16 and will not work if you try to use newly created wallets in older versions. Existing wallets that were created with older versions are not affected by this.

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

Denial-of-Service vulnerability

A denial-of-service vulnerability exploitable by miners has been discovered in Aixcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of the vulnerable versions to 0.16.3 as soon as possible.

0.16.3 change log

Consensus

#14249 696b936 Fix crash bug with duplicate inputs within a transaction (TheBlueMatt, sdaftuar)

RPC and other APIs

#13547 212ef1f Make signrawtransaction* give an error when amount is needed but missing (ajtowns)

Miscellaneous

A new -addresstype argument has been added, which supports legacy, p2sh-segwit (default), and bech32 addresses. It controls what kind of addresses are produced by getnewaddress, getaccountaddress, and createmultisigaddress. A -changetype argument has also been added, with the same options, and by default equal to -addresstype, to control which kind of change is used.

A new address_type parameter has been added to the getnewaddress and addmultisigaddress RPCs to specify which type of address to generate. A change_type argument has been added to the fundrawtransaction RPC to override the -changetype argument for specific transactions.

All segwit addresses created through getnewaddress or *multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a segwit address will work, as long as the wallet file is up to date.
All segwit keys in the wallet get an implicit redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a segwit address will work

Note that some RPCs do not yet support segwit addresses. Notably, signmessage/verifymessage doesn’t support segwit addresses, nor does importmulti at this time. Support for segwit in those RPCs will continue to be added in future versions.

P2WPKH change outputs are now used by default if any destination in the transaction is a P2WPKH or P2WSH output. This is done to ensure the change output is as indistinguishable from the other outputs as possible in either case.

BIP173 (Bech32) Address support (“bc1…” addresses)

Full support for native segwit addresses (BIP173 / Bech32) has now been added. This includes the ability to send to BIP173 addresses (including non-v0 ones), and generating these addresses (including as default new addresses, see above).

A checkbox has been added to the GUI to select whether a Bech32 address or P2SH-wrapped address should be generated when using segwit addresses. When launched with -addresstype=bech32 it is checked by default. When launched with -addresstype=legacy it is unchecked and disabled.

HD-wallets by default

Due to a backward-incompatible change in the wallet database, wallets created with version 0.16.0 will be rejected by previous versions. Also, version 0.16.0 will only create hierarchical deterministic (HD) wallets. Note that this only applies to new wallets; wallets made with previous versions will not be upgraded to be HD.

Replace-By-Fee by default in GUI

The send screen now uses BIP125 RBF by default, regardless of -walletrbf. There is a checkbox to mark the transaction as final.

The RPC default remains unchanged: to use RBF, launch with -walletrbf=1 or use the replaceable argument for individual transactions.

Wallets directory configuration (`-walletdir`)

Aixcoin Core now has more flexibility in where the wallets directory can be located. Previously wallet database files were stored at the top level of the aixcoin data directory. The behavior is now:

For new installations (where the data directory doesn’t already exist), wallets will now be stored in a new wallets/ subdirectory inside the data directory by default.
For existing nodes (where the data directory already exists), wallets will be stored in the data directory root by default. If a wallets/ subdirectory already exists in the data directory root, then wallets will be stored in the wallets/ subdirectory by default.
The location of the wallets directory can be overridden by specifying a -walletdir=<path> option where <path> can be an absolute path to a directory or directory symlink.

Care should be taken when choosing the wallets directory location, as if it becomes unavailable during operation, funds may be lost.

Build: Minimum GCC bumped to 4.8.x

The minimum version of the GCC compiler required to compile Aixcoin Core is now 4.8. No effort will be made to support older versions of GCC. See discussion in issue #11732 for more information. The minimum version for the Clang compiler is still 3.3. Other minimum dependency versions can be found in doc/dependencies.md in the repository.

Support for signalling pruned nodes (BIP159)

Pruned nodes can now signal BIP159’s NODE_NETWORK_LIMITED using service bits, in preparation for full BIP159 support in later versions. This would allow pruned nodes to serve the most recent blocks. However, the current change does not yet include support for connecting to these pruned peers.

Performance: SHA256 assembly enabled by default

The SHA256 hashing optimizations for architectures supporting SSE4, which lead to ~50% speedups in SHA256 on supported hardware (~5% faster synchronization and block validation), have now been enabled by default. In previous versions they were enabled using the --enable-experimental-asm flag when building, but are now the default and no longer deemed experimental.

GUI changes

Uses of “µAIX” in the GUI now also show the more colloquial term “bits”, specified in BIP176.
The option to reuse a previous address has now been removed. This was justified by the need to “resend” an invoice, but now that we have the request history, that need should be gone.
Support for searching by TXID has been added, rather than just address and label.
A “Use available balance” option has been added to the send coins dialog, to add the remaining available wallet balance to a transaction output.
A toggle for unblinding the password fields on the password dialog has been added.

RPC changes

New `rescanblockchain` RPC

A new RPC rescanblockchain has been added to manually invoke a blockchain rescan. The RPC supports start and end-height arguments for the rescan, and can be used in a multiwallet environment to rescan the blockchain at runtime.

New `savemempool` RPC

A new savemempool RPC has been added which allows the current mempool to be saved to disk at any time to avoid it being lost due to crashes / power loss.

Safe mode disabled by default

Safe mode is now disabled by default and must be manually enabled (with -disablesafemode=0) if you wish to use it. Safe mode is a feature that disables a subset of RPC calls - mostly related to the wallet and sending - automatically in case certain problem conditions with the network are detected. However, developers have come to regard these checks as not reliable enough to act on automatically. Even with safe mode disabled, they will still cause warnings in the warnings field of the getneworkinfo RPC and launch the -alertnotify command.

Renamed script for creating JSON-RPC credentials

The share/rpcuser/rpcuser.py script was renamed to share/rpcauth/rpcauth.py. This script can be used to create rpcauth credentials for a JSON-RPC user.

Validateaddress improvements

The validateaddress RPC output has been extended with a few new fields, and support for segwit addresses (both P2SH and Bech32). Specifically:

A new field iswitness is True for P2WPKH and P2WSH addresses (“bc1…” addresses), but not for P2SH-wrapped segwit addresses (see below).
The existing field isscript will now also report True for P2WSH addresses.
A new field embedded is present for all script addresses where the script is known and matches something that can be interpreted as a known address. This is particularly true for P2SH-P2WPKH and P2SH-P2WSH addresses. The value for embedded includes much of the information validateaddress would report if invoked directly on the embedded address.
For multisig scripts a new pubkeys field was added that reports the full public keys involved in the script (if known). This is a replacement for the existing addresses field (which reports the same information but encoded as P2PKH addresses), represented in a more useful and less confusing way. The addresses field remains present for non-segwit addresses for backward compatibility.
For all single-key addresses with known key (even when wrapped in P2SH or P2WSH), the pubkey field will be present. In particular, this means that invoking validateaddress on the output of getnewaddress will always report the pubkey, even when the address type is P2SH-P2WPKH.

Low-level changes

The deprecated RPC getinfo was removed. It is recommended that the more specific RPCs are used:
- getblockchaininfo
- getnetworkinfo
- getwalletinfo
- getmininginfo
The wallet RPC getreceivedbyaddress will return an error if called with an address not in the wallet.
The wallet RPC addwitnessaddress was deprecated and will be removed in version 0.17, set the address_type argument of getnewaddress, or option -addresstype=[bech32|p2sh-segwit] instead.
dumpwallet now includes hex-encoded scripts from the wallet in the dumpfile, and importwallet now imports these scripts, but corresponding addresses may not be added correctly or a manual rescan may be required to find relevant transactions.
The RPC getblockchaininfo now includes an errors field.
A new blockhash parameter has been added to the getrawtransaction RPC which allows for a raw transaction to be fetched from a specific block if known, even without -txindex enabled.
The decoderawtransaction and fundrawtransaction RPCs now have optional iswitness parameters to override the heuristic witness checks if necessary.
The walletpassphrase timeout is now clamped to 2^30 seconds.
Using addresses with the createmultisig RPC is now deprecated, and will be removed in a later version. Public keys should be used instead.
Blockchain rescans now no longer lock the wallet for the entire rescan process, so other RPCs can now be used at the same time (although results of balances / transactions may be incorrect or incomplete until the rescan is complete).
The logging RPC has now been made public rather than hidden.
An initialblockdownload boolean has been added to the getblockchaininfo RPC to indicate whether the node is currently in IBD or not.
minrelaytxfee is now included in the output of getmempoolinfo

Other changed command-line options

-debuglogfile=<file> can be used to specify an alternative debug logging file.
aixcoin-cli now has an -stdinrpcpass option to allow the RPC password to be read from standard input.
The -usehd option has been removed.
aixcoin-cli now supports a new -getinfo flag which returns an output like that of the now-removed getinfo RPC.

Testing changes

The default regtest JSON-RPC port has been changed to 18443 to avoid conflict with testnet’s default of 18332.
Segwit is now always active in regtest mode by default. Thus, if you upgrade a regtest node you will need to either -reindex or use the old rules by adding vbparams=segwit:0:999999999999 to your regtest aixcoin.conf. Failure to do this will result in a CheckBlockIndex() assertion failure that will look like: Assertion `(pindexFirstNeverProcessed != nullptr) == (pindex->nChainTx == 0)’ failed.

Aixcoin Core 0.15.2

Fri, 28 Sep 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.15.2 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.15.2/

This is a new minor version release, including various bugfixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

The first time you run version 0.15.0 or higher, your chainstate database will be converted to a new format, which will take anywhere from a few minutes to half an hour, depending on the speed of your machine.

The file format of fee_estimates.dat changed in version 0.15.0. Hence, a downgrade from version 0.15 or upgrade to version 0.15 will cause all fee estimates to be discarded.

Downgrading warning

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

Network fork safety enhancements

A number of changes to the way Aixcoin Core deals with peer connections and invalid blocks have been made, as a safety precaution against blockchain forks and misbehaving peers.

Unrequested blocks with less work than the minimum-chain-work are now no longer processed even if they have more work than the tip (a potential issue during IBD where the tip may have low-work). This prevents peers wasting the resources of a node.
Peers which provide a chain with less work than the minimum-chain-work during IBD will now be disconnected.
For a given outbound peer, we now check whether their best known block has at least as much work as our tip. If it doesn’t, and if we still haven’t heard about a block with sufficient work after a 20 minute timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer. We protect 4 of our outbound peers from being disconnected by this logic to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
Outbound (non-manual) peers that serve us block headers that are already known to be invalid (other than compact block announcements, because BIP 152 explicitly permits nodes to relay compact blocks before fully validating them) will now be disconnected.
If the chain tip has not been advanced for over 30 minutes, we now assume the tip may be stale and will try to connect to an additional outbound peer. A periodic check ensures that if this extra peer connection is in use, we will disconnect the peer that least recently announced a new block.
The set of all known invalid-themselves blocks (i.e. blocks which we attempted to connect but which were found to be invalid) are now tracked and used to check if new headers build on an invalid chain. This ensures that everything that descends from an invalid block is marked as such.

Miner block size limiting deprecated

Though blockmaxweight has been preferred for limiting the size of blocks returned by getblocktemplate since 0.13.0, blockmaxsize remained as an option for those who wished to limit their block size directly. Using this option resulted in a few UI issues as well as non-optimal fee selection and ever-so-slightly worse performance, and has thus now been deprecated. Further, the blockmaxsize option is now used only to calculate an implied blockmaxweight, instead of limiting block size directly. Any miners who wish to limit their blocks by size, instead of by weight, will have to do so manually by removing transactions from their block template directly.

GUI settings backed up on reset

The GUI settings will now be written to guisettings.ini.bak in the data directory before wiping them when the -resetguisettings argument is used. This can be used to retroactively troubleshoot issues due to the GUI settings.

Duplicate wallets disallowed

Previously, it was possible to open the same wallet twice by manually copying the wallet file, causing issues when both were opened simultaneously. It is no longer possible to open copies of the same wallet.

Debug `-minimumchainwork` argument added

A hidden debug argument -minimumchainwork has been added to allow a custom minimum work value to be used when validating a chain.

Low-level RPC changes

The “currentblocksize” value in getmininginfo has been removed.
dumpwallet no longer allows overwriting files. This is a security measure as well as prevents dangerous user mistakes.
backupwallet will now fail when attempting to backup to source file, rather than destroying the wallet.
listsinceblock will now throw an error if an unknown blockhash argument value is passed, instead of returning a list of all wallet transactions since the genesis block. The behaviour is unchanged when an empty string is provided.

Aixcoin Core 0.15.0.1

Tue, 19 Sep 2017 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.15.0.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.15.0.1/

This is a minor bug fix for 0.15.0.

Please report bugs using the issue tracker at GitHub:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

How to Upgrade

The file format of fee_estimates.dat changed in version 0.15.0. Hence, a downgrade from version 0.15.0 or upgrade to version 0.15.0 will cause all fee estimates to be discarded.

Downgrading warning

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

GUI startup crash issue

After upgrade to 0.15.0, some clients would crash at startup because a custom fee setting was configured that no longer exists in the GUI. This is a minimal patch to avoid this issue from occuring.

0.15.0.1 Change log

#11332 46c8d23 Fix possible crash with invalid nCustomFeeRadio in QSettings (achow101, TheBlueMatt)

Also the manpages were updated, as this was forgotten for 0.15.0.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notes for 0.15.0

Current SegWit support

Version 0.15.0 supports adding a segregated witness address via the addwitnessaddress RPC, but please note that this is a testing/expert RPC, which does not guarantee recovery from backup. Only use this RPC if you know what you are doing. More complete wallet support for segregated witness is coming in a next version.

Rescanning with encrypted wallets

As in previous versions, when using an encrypted HD wallet, the keypool cannot be topped up without unlocking the wallet. This means that currently, in order to recover from a backup of an encrypted HD wallet, the user must unlock the wallet with a really long timeout and manually trigger a rescan, otherwise they risk missing some keys when auto-topup cannot run. Unfortunately there is no rescan RPC in this version, that will be included in a future version, so for now a rescan can be triggered using one of the import* commands, using a dummy address generated by another (trusted) wallet.

Notable changes

Performance Improvements

Version 0.15 contains a number of significant performance improvements, which make Initial Block Download, startup, transaction and block validation much faster:

The chainstate database (which is used for tracking UTXOs) has been changed from a per-transaction model to a per-output model (See PR 10195). Advantages of this model are that it:
- avoids the CPU overhead of deserializing and serializing the unused outputs;
- has more predictable memory usage;
- uses simpler code;
- is adaptable to various future cache flushing strategies.
As a result, validating the blockchain during Initial Block Download (IBD) and reindex is ~30-40% faster, uses 10-20% less memory, and flushes to disk far less frequently. The only downside is that the on-disk database is 15% larger. During the conversion from the previous format a few extra gigabytes may be used.
Earlier versions experienced a spike in memory usage while flushing UTXO updates to disk. As a result, only half of the available memory was actually used as cache, and the other half was reserved to accommodate flushing. This is no longer the case (See PR 10148), and the entirety of the available cache (see -dbcache) is now actually used as cache. This reduces the flushing frequency by a factor 2 or more.
In previous versions, signature validation for transactions has been cached when the transaction is accepted to the mempool. Version 0.15 extends this to cache the entire script validity (See PR 10192). This means that if a transaction in a block has already been accepted to the mempool, the scriptSig does not need to be re-evaluated. Empirical tests show that this results in new block validation being 40-50% faster.
LevelDB has been upgraded to version 1.20 (See PR 10544). This version contains hardware acceleration for CRC on architectures supporting SSE 4.2. As a result, synchronization and block validation are now faster.
SHA256 hashing has been optimized for architectures supporting SSE 4 (See PR 10821). SHA256 is around 50% faster on supported hardware, which results in around 5% faster IBD and block validation. In version 0.15, SHA256 hardware optimization is disabled in release builds by default, but can be enabled by using --enable-experimental-asm when building.
Refill of the keypool no longer flushes the wallet between each key which resulted in a ~20x speedup in creating a new wallet. Part of this speedup was used to increase the default keypool to 1000 keys to make recovery more robust. (See PR 10831).

Fee Estimation Improvements

Fee estimation has been significantly improved in version 0.15, with more accurate fee estimates used by the wallet and a wider range of options for advanced users of the estimatesmartfee and estimaterawfee RPCs (See PR 10199).

Changes to internal logic and wallet behavior

Internally, estimates are now tracked on 3 different time horizons. This allows for longer targets and means estimates adjust more quickly to changes in conditions.
Estimates can now be conservative or economical. Conservative estimates use longer time horizons to produce an estimate which is less susceptible to rapid changes in fee conditions. Economical estimates use shorter time horizons and will be more affected by short-term changes in fee conditions. Economical estimates may be considerably lower during periods of low transaction activity (for example over weekends), but may result in transactions being unconfirmed if prevailing fees increase rapidly.
By default, the wallet will use conservative fee estimates to increase the reliability of transactions being confirmed within the desired target. For transactions that are marked as replaceable, the wallet will use an economical estimate by default, since the fee can be ‘bumped’ if the fee conditions change rapidly (See PR 10589).
Estimates can now be made for confirmation targets up to 1008 blocks (one week).
More data on historical fee rates is stored, leading to more precise fee estimates.
Transactions which leave the mempool due to eviction or other non-confirmed reasons are now taken into account by the fee estimation logic, leading to more accurate fee estimates.
The fee estimation logic will make sure enough data has been gathered to return a meaningful estimate. If there is insufficient data, a fallback default fee is used.

Changes to fee estimate RPCs

The estimatefee RPC is now deprecated in favor of using only estimatesmartfee (which is the implementation used by the GUI)
The estimatesmartfee RPC interface has been changed (See PR 10707):
- The nblocks argument has been renamed to conf_target (to be consistent with other RPC methods).
- An estimate_mode argument has been added. This argument takes one of the following strings: CONSERVATIVE, ECONOMICAL or UNSET (which defaults to CONSERVATIVE).
- The RPC return object now contains an errors member, which returns errors encountered during processing.
- If Aixcoin Core has not been running for long enough and has not seen enough blocks or transactions to produce an accurate fee estimation, an error will be returned (previously a value of -1 was used to indicate an error, which could be confused for a feerate).
A new estimaterawfee RPC is added to provide raw fee data. External clients can query and use this data in their own fee estimation logic.

Multi-wallet support

Aixcoin Core now supports loading multiple, separate wallets (See PR 8694, PR 10849). The wallets are completely separated, with individual balances, keys and received transactions.

Multi-wallet is enabled by using more than one -wallet argument when starting Aixcoin, either on the command line or in the Aixcoin config file.

In Aixcoin-Qt, only the first wallet will be displayed and accessible for creating and signing transactions. GUI selectable multiple wallets will be supported in a future version. However, even in 0.15 other loaded wallets will remain synchronized to the node’s current tip in the background. This can be useful if running a pruned node, since loading a wallet where the most recent sync is beyond the pruned height results in having to download and revalidate the whole blockchain. Continuing to synchronize all wallets in the background avoids this problem.

Aixcoin Core 0.15.0 contains the following changes to the RPC interface and aixcoin-cli for multi-wallet:

When running Aixcoin Core with a single wallet, there are no changes to the RPC interface or aixcoin-cli. All RPC calls and aixcoin-cli commands continue to work as before.
When running Aixcoin Core with multi-wallet, all node-level RPC methods continue to work as before. HTTP RPC requests should be send to the normal <RPC IP address>:<RPC port> endpoint, and aixcoin-cli commands should be run as before. A node-level RPC method is any method which does not require access to the wallet.
When running Aixcoin Core with multi-wallet, wallet-level RPC methods must specify the wallet for which they’re intended in every request. HTTP RPC requests should be send to the <RPC IP address>:<RPC port>/wallet/<wallet name> endpoint, for example 127.0.0.1:8332/wallet/wallet1.dat. aixcoin-cli commands should be run with a -rpcwallet option, for example aixcoin-cli -rpcwallet=wallet1.dat getbalance.
A new node-level listwallets RPC method is added to display which wallets are currently loaded. The names returned by this method are the same as those used in the HTTP endpoint and for the rpcwallet argument.

Note that while multi-wallet is now fully supported, the RPC multi-wallet interface should be considered unstable for version 0.15.0, and there may backwards-incompatible changes in future versions.

Replace-by-fee control in the GUI

Aixcoin Core has supported creating opt-in replace-by-fee (RBF) transactions since version 0.12.0, and since version 0.14.0 has included a bumpfee RPC method to replace unconfirmed opt-in RBF transactions with a new transaction that pays a higher fee.

In version 0.15, creating an opt-in RBF transaction and replacing the unconfirmed transaction with a higher-fee transaction are both supported in the GUI (See PR 9592).

Removal of Coin Age Priority

In previous versions of Aixcoin Core, a portion of each block could be reserved for transactions based on the age and value of UTXOs they spent. This concept (Coin Age Priority) is a policy choice by miners, and there are no consensus rules around the inclusion of Coin Age Priority transactions in blocks. In practice, only a few miners continue to use Coin Age Priority for transaction selection in blocks. Aixcoin Core 0.15 removes all remaining support for Coin Age Priority (See PR 9602). This has the following implications:

The concept of free transactions has been removed. High Coin Age Priority transactions would previously be allowed to be relayed even if they didn’t attach a miner fee. This is no longer possible since there is no concept of Coin Age Priority. The -limitfreerelay and -relaypriority options which controlled relay of free transactions have therefore been removed.
The -sendfreetransactions option has been removed, since almost all miners do not include transactions which do not attach a transaction fee.
The -blockprioritysize option has been removed.
The estimatepriority and estimatesmartpriority RPCs have been removed.
The getmempoolancestors, getmempooldescendants, getmempoolentry and getrawmempool RPCs no longer return startingpriority and currentpriority.
The prioritisetransaction RPC no longer takes a priority_delta argument, which is replaced by a dummy argument for backwards compatibility with clients using positional arguments. The RPC is still used to change the apparent fee-rate of the transaction by using the fee_delta argument.
-minrelaytxfee can now be set to 0. If minrelaytxfee is set, then fees smaller than minrelaytxfee (per kB) are rejected from relaying, mining and transaction creation. This defaults to 1000 satoshi/kB.
The -printpriority option has been updated to only output the fee rate and hash of transactions included in a block by the mining code.

Mempool Persistence Across Restarts

Version 0.14 introduced mempool persistence across restarts (the mempool is saved to a mempool.dat file in the data directory prior to shutdown and restores the mempool when the node is restarted). Version 0.15 allows this feature to be switched on or off using the -persistmempool command-line option (See PR 9966). By default, the option is set to true, and the mempool is saved on shutdown and reloaded on startup. If set to false, the mempool.dat file will not be loaded on startup or saved on shutdown.

New RPC methods

Version 0.15 introduces several new RPC methods:

abortrescan stops current wallet rescan, e.g. when triggered by an importprivkey call (See PR 10208).
combinerawtransaction accepts a JSON array of raw transactions and combines them into a single raw transaction (See PR 10571).
estimaterawfee returns raw fee data so that customized logic can be implemented to analyze the data and calculate estimates. See Fee Estimation Improvements for full details on changes to the fee estimation logic and interface.
getchaintxstats returns statistics about the total number and rate of transactions in the chain (See PR 9733).
listwallets lists wallets which are currently loaded. See the Multi-wallet section of these release notes for full details (See Multi-wallet support).
uptime returns the total runtime of the aixcoind server since its last start (See PR 10400).

Low-level RPC changes

When using Aixcoin Core in multi-wallet mode, RPC requests for wallet methods must specify the wallet that they’re intended for. See Multi-wallet support for full details.
The new database model no longer stores information about transaction versions of unspent outputs (See Performance improvements). This means that:
- The gettxout RPC no longer has a version field in the response.
- The gettxoutsetinfo RPC reports hash_serialized_2 instead of hash_serialized, which does not commit to the transaction versions of unspent outputs, but does commit to the height and coinbase information.
- The getutxos REST path no longer reports the txvers field in JSON format, and always reports 0 for transaction versions in the binary format
The estimatefee RPC is deprecated. Clients should switch to using the estimatesmartfee RPC, which returns better fee estimates. See Fee Estimation Improvements for full details on changes to the fee estimation logic and interface.
The gettxoutsetinfo response now contains disk_size and bogosize instead of bytes_serialized. The first is a more accurate estimate of actual disk usage, but is not deterministic. The second is unrelated to disk usage, but is a database-independent metric of UTXO set size: it counts every UTXO entry as 50 + the length of its scriptPubKey (See PR 10426).
signrawtransaction can no longer be used to combine multiple transactions into a single transaction. Instead, use the new combinerawtransaction RPC (See PR 10571).
fundrawtransaction no longer accepts a reserveChangeKey option. This option used to allow RPC users to fund a raw transaction using an key from the keypool for the change address without removing it from the available keys in the keypool. The key could then be re-used for a getnewaddress call, which could potentially result in confusing or dangerous behaviour (See PR 10784).
estimatepriority and estimatesmartpriority have been removed. See Removal of Coin Age Priority.
The listunspent RPC now takes a query_options argument (see PR 8952), which is a JSON object containing one or more of the following members:
- minimumAmount - a number specifying the minimum value of each UTXO
- maximumAmount - a number specifying the maximum value of each UTXO
- maximumCount - a number specifying the minimum number of UTXOs
- minimumSumAmount - a number specifying the minimum sum value of all UTXOs
The getmempoolancestors, getmempooldescendants, getmempoolentry and getrawmempool RPCs no longer return startingpriority and currentpriority. See Removal of Coin Age Priority.
The dumpwallet RPC now returns the full absolute path to the dumped wallet. It used to return no value, even if successful (See PR 9740).
In the getpeerinfo RPC, the return object for each peer now returns an addrbind member, which contains the ip address and port of the connection to the peer. This is in addition to the addrlocal member which contains the ip address and port of the local node as reported by the peer (See PR 10478).
The disconnectnode RPC can now disconnect a node specified by node ID (as well as by IP address/port). To disconnect a node based on node ID, call the RPC with the new nodeid argument (See PR 10143).
The second argument in prioritisetransaction has been renamed from priority_delta to dummy since Aixcoin Core no longer has a concept of coin age priority. The dummy argument has no functional effect, but is retained for positional argument compatibility. See Removal of Coin Age Priority.
The resendwallettransactions RPC throws an error if the -walletbroadcast option is set to false (See PR 10995).
The second argument in the submitblock RPC argument has been renamed from parameters to dummy. This argument never had any effect, and the renaming is simply to communicate this fact to the user (See PR 10191) (Clients should, however, use positional arguments for submitblock in order to be compatible with BIP 22.)
The verbose argument of getblock has been renamed to verbosity and now takes an integer from 0 to 2. Verbose level 0 is equivalent to verbose=false. Verbose level 1 is equivalent to verbose=true. Verbose level 2 will give the full transaction details of each transaction in the output as given by getrawtransaction. The old behavior of using the verbose named argument and a boolean value is still maintained for compatibility.
Error codes have been updated to be more accurate for the following error cases (See PR 9853):
- getblock now returns RPC_MISC_ERROR if the block can’t be found on disk (for example if the block has been pruned). Previously returned RPC_INTERNAL_ERROR.

Aixcoin Core 0.14.3

Fri, 28 Sep 2018 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.14.3 is now available from:

https://aixcoin.org/bin/aixcoin-core-0.14.3/

This is a new minor version release, including various bugfixes and performance improvements.

Please report bugs using the issue tracker at github:

https://github.com/aixcoin/aixcoin/issues

To receive security and update notifications, please subscribe to:

https://aixcoin-core.github.io/en/list/announcements/join/

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later.

Microsoft ended support for Windows XP on April 8th, 2014, No attempt is made to prevent installing or running the software on Windows XP, you can still do so at your own risk but be aware that there are known instabilities and issues. Please do not report issues about Windows XP to the issue tracker.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

Denial-of-Service vulnerability CVE-2018-17144 ——————————-

Known Bugs

Since 0.14.0 the approximate transaction fee shown in Aixcoin-Qt when using coin control and smart fee estimation does not reflect any change in target from the smart fee slider. It will only present an approximate fee calculated using the default target. The fee calculated using the correct target is still applied to the transaction and shown in the final send confirmation dialog.

0.14.3 Change log

Detailed release notes follow. This overview includes changes that affect behavior, not code moves, refactors and string updates. For convenience in locating the code changes and accompanying discussion, both the pull request and git merge commit are mentioned.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

miniupnp CVE-2017-8798

Bundled miniupnpc was updated to 2.0.20170509. This fixes an integer signedness error (present in MiniUPnPc v1.4.20101221 through v2.0) that allows remote attackers (within the LAN) to cause a denial of service or possibly have unspecified other impact.

This only affects users that have explicitly enabled UPnP through the GUI setting or through the -upnp option, as since the last UPnP vulnerability (in Aixcoin Core 0.10.3) it has been disabled by default.

If you use this option, it is recommended to upgrade to this version as soon as possible.

Aixcoin Core 0.14.1

Sat, 22 Apr 2017 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.14.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.14.1/

This is a new minor version release, including various bugfixes and performance improvements, as well as updated translations.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

RPC changes

The first positional argument of createrawtransaction was renamed from transactions to inputs.
The argument of disconnectnode was renamed from node to address.

These interface changes break compatibility with 0.14.0, when the named arguments functionality, introduced in 0.14.0, is used. Client software using these calls with named arguments needs to be updated.

Mining

In previous versions, getblocktemplate required segwit support from downstream clients/miners once the feature activated on the network. In this version, it now supports non-segwit clients even after activation, by removing all segwit transactions from the returned block template. This allows non-segwit miners to continue functioning correctly even after segwit has activated.

Due to the limitations in previous versions, getblocktemplate also recommended non-segwit clients to not signal for the segwit version-bit. Since this is no longer an issue, getblocktemplate now always recommends signalling segwit for all miners. This is safe because ability to enforce the rule is the only required criteria for safe activation, not actually producing segwit-enabled blocks.

UTXO memory accounting

Memory usage for the UTXO cache is being calculated more accurately, so that the configured limit (-dbcache) will be respected when memory usage peaks during cache flushes. The memory accounting in prior releases is estimated to only account for half the actual peak utilization.

The default -dbcache has also been changed in this release to 450MiB. Users who currently set -dbcache to a high value (e.g. to keep the UTXO more fully cached in memory) should consider increasing this setting in order to achieve the same cache performance as prior releases. Users on low-memory systems (such as systems with 1GB or less) should consider specifying a lower value for this parameter.

Additional information relating to running on low-memory systems can be found here: reducing-aixcoind-memory-usage.md.

Aixcoin Core 0.14.0

Wed, 08 Mar 2017 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.14.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.14.0/

This is a new major version release, including new features, various bugfixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at github:

Compatibility

Aixcoin Core is extensively tested on multiple operating systems using the Linux kernel, macOS 10.8+, and Windows Vista and later.

Aixcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

Notable changes

Performance Improvements

Validation speed and network propagation performance have been greatly improved, leading to much shorter sync and initial block download times.

The script signature cache has been reimplemented as a “cuckoo cache”, allowing for more signatures to be cached and faster lookups.
Assumed-valid blocks have been introduced which allows script validation to be skipped for ancestors of known-good blocks, without changing the security model. See below for more details.
In some cases, compact blocks are now relayed before being fully validated as per BIP152.
P2P networking has been refactored with a focus on concurrency and throughput. Network operations are no longer bottlenecked by validation. As a result, block fetching is several times faster than previous releases in many cases.
The UTXO cache now claims unused mempool memory. This speeds up initial block download as UTXO lookups are a major bottleneck there, and there is no use for the mempool at that stage.

Manual Pruning

Aixcoin Core has supported automatically pruning the blockchain since 0.11. Pruning the blockchain allows for significant storage space savings as the vast majority of the downloaded data can be discarded after processing so very little of it remains on the disk.

Manual block pruning can now be enabled by setting -prune=1. Once that is set, the RPC command pruneblockchain can be used to prune the blockchain up to the specified height or timestamp.

`getinfo` Deprecated

The getinfo RPC command has been deprecated. Each field in the RPC call has been moved to another command’s output with that command also giving additional information that getinfo did not provide. The following table shows where each field has been moved to:

`getinfo` field	Moved to
`"version"`	`getnetworkinfo()["version"]`
`"protocolversion"`	`getnetworkinfo()["protocolversion"]`
`"walletversion"`	`getwalletinfo()["walletversion"]`
`"balance"`	`getwalletinfo()["balance"]`
`"blocks"`	`getblockchaininfo()["blocks"]`
`"timeoffset"`	`getnetworkinfo()["timeoffset"]`
`"connections"`	`getnetworkinfo()["connections"]`
`"proxy"`	`getnetworkinfo()["networks"][0]["proxy"]`
`"difficulty"`	`getblockchaininfo()["difficulty"]`
`"testnet"`	`getblockchaininfo()["chain"] == "test"`
`"keypoololdest"`	`getwalletinfo()["keypoololdest"]`
`"keypoolsize"`	`getwalletinfo()["keypoolsize"]`
`"unlocked_until"`	`getwalletinfo()["unlocked_until"]`
`"paytxfee"`	`getwalletinfo()["paytxfee"]`
`"relayfee"`	`getnetworkinfo()["relayfee"]`
`"errors"`	`getnetworkinfo()["warnings"]`

ZMQ On Windows

Previously the ZeroMQ notification system was unavailable on Windows due to various issues with ZMQ. These have been fixed upstream and now ZMQ can be used on Windows. Please see this document for help with using ZMQ in general.

Nested RPC Commands in Debug Console

The ability to nest RPC commands has been added to the debug console. This allows users to have the output of a command become the input to another command without running the commands separately.

The nested RPC commands use bracket syntax (i.e. getwalletinfo()) and can be nested (i.e. getblock(getblockhash(1))). Simple queries can be done with square brackets where object values are accessed with either an array index or a non-quoted string (i.e. listunspent()[0][txid]). Both commas and spaces can be used to separate parameters in both the bracket syntax and normal RPC command syntax.

Network Activity Toggle

A RPC command and GUI toggle have been added to enable or disable all p2p network activity. The network status icon in the bottom right hand corner is now the GUI toggle. Clicking the icon will either enable or disable all p2p network activity. If network activity is disabled, the icon will be grayed out with an X on top of it.

Additionally the setnetworkactive RPC command has been added which does the same thing as the GUI icon. The command takes one boolean parameter, true enables networking and false disables it.

When Aixcoin Core is out-of-sync on startup, a semi-transparent information layer will be shown over top of the normal display. This layer contains details about the current sync progress and estimates the amount of time remaining to finish syncing. This layer can also be hidden and subsequently unhidden by clicking on the progress bar at the bottom of the window.

Support for JSON-RPC Named Arguments

Commands sent over the JSON-RPC interface and through the aixcoin-cli binary can now use named arguments. This follows the JSON-RPC specification for passing parameters by-name with an object.

aixcoin-cli has been updated to support this by parsing name=value arguments when the -named option is given.

Some examples:

src/aixcoin-cli -named help command="help"
src/aixcoin-cli -named getblockhash height=0
src/aixcoin-cli -named getblock blockhash=000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
src/aixcoin-cli -named sendtoaddress address="(snip)" amount="1.0" subtractfeefromamount=true

The order of arguments doesn’t matter in this case. Named arguments are also useful to leave out arguments that should stay at their default value. The rarely-used arguments comment and comment_to to sendtoaddress, for example, can be left out. However, this is not yet implemented for many RPC calls, this is expected to land in a later release.

The RPC server remains fully backwards compatible with positional arguments.

Opt into RBF When Sending

A new startup option, -walletrbf, has been added to allow users to have all transactions sent opt into RBF support. The default value for this option is currently false, so transactions will not opt into RBF by default. The new bumpfee RPC can be used to replace transactions that opt into RBF.

Sensitive Data Is No Longer Stored In Debug Console History

The debug console maintains a history of previously entered commands that can be accessed by pressing the Up-arrow key so that users can easily reuse previously entered commands. Commands which have sensitive information such as passphrases and private keys will now have a (...) in place of the parameters when accessed through the history.

Retaining the Mempool Across Restarts

The mempool will be saved to the data directory prior to shutdown to a mempool.dat file. This file preserves the mempool so that when the node restarts the mempool can be filled with transactions without waiting for new transactions to be created. This will also preserve any changes made to a transaction through commands such as prioritisetransaction so that those changes will not be lost.

Final Alert

The Alert System was disabled and deprecated in Aixcoin Core 0.12.1 and removed in 0.13.0. The Alert System was retired with a maximum sequence final alert which causes any nodes supporting the Alert System to display a static hard-coded “Alert Key Compromised” message which also prevents any other alerts from overriding it. This final alert is hard-coded into this release so that all old nodes receive the final alert.

GUI Changes

After resetting the options by clicking the Reset Options button in the options dialog or with the -resetguioptions startup option, the user will be prompted to choose the data directory again. This is to ensure that custom data directories will be kept after the option reset which clears the custom data directory set via the choose datadir dialog.
Multiple peers can now be selected in the list of peers in the debug window. This allows for users to ban or disconnect multiple peers simultaneously instead of banning them one at a time.
An indicator has been added to the bottom right hand corner of the main window to indicate whether the wallet being used is a HD wallet. This icon will be grayed out with an X on top of it if the wallet is not a HD wallet.

Low-level RPC changes

importprunedfunds only accepts two required arguments. Some versions accept an optional third arg, which was always ignored. Make sure to never pass more than two arguments.
The first boolean argument to getaddednodeinfo has been removed. This is an incompatible change.
RPC command getmininginfo loses the “testnet” field in favor of the more generic “chain” (which has been present for years).
A new RPC command preciousblock has been added which marks a block as precious. A precious block will be treated as if it were received earlier than a competing block.
A new RPC command importmulti has been added which receives an array of JSON objects representing the intention of importing a public key, a private key, an address and script/p2sh
Use of getrawtransaction for retrieving confirmed transactions with unspent outputs has been deprecated. For now this will still work, but in the future it may change to only be able to retrieve information about transactions in the mempool or if txindex is enabled.
A new RPC command getmemoryinfo has been added which will return information about the memory usage of Aixcoin Core. This was added in conjunction with optimizations to memory management. See Pull #8753 for more information.
A new RPC command bumpfee has been added which allows replacing an unconfirmed wallet transaction that signaled RBF (see the -walletrbf startup option above) with a new transaction that pays a higher fee, and should be more likely to get confirmed quickly.

HTTP REST Changes

UTXO set query (GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n> /.../<txid>-<n>.<bin|hex|json>) responses were changed to return status code HTTP_BAD_REQUEST (400) instead of HTTP_INTERNAL_SERVER_ERROR (500) when requests contain invalid parameters.

Minimum Fee Rate Policies

Since the changes in 0.12 to automatically limit the size of the mempool and improve the performance of block creation in mining code it has not been important for relay nodes or miners to set -minrelaytxfee. With this release the following concepts that were tied to this option have been separated out:

incremental relay fee used for calculating BIP 125 replacement and mempool limiting. (1000 satoshis/kB)
calculation of threshold for a dust output. (effectively 3 * 1000 satoshis/kB)
minimum fee rate of a package of transactions to be included in a block created by the mining code. If miners wish to set this minimum they can use the new -blockmintxfee option. (defaults to 1000 satoshis/kB)

The -minrelaytxfee option continues to exist but is recommended to be left unset.

Fee Estimation Changes

Since 0.13.2 fee estimation for a confirmation target of 1 block has been disabled. The fee slider will no longer be able to choose a target of 1 block. This is only a minor behavior change as there was often insufficient data for this target anyway. estimatefee 1 will now always return -1 and estimatesmartfee 1 will start searching at a target of 2.
The default target for fee estimation is changed to 6 blocks in both the GUI (previously 25) and for RPC calls (previously 2).

Removal of Priority Estimation

Estimation of “priority” needed for a transaction to be included within a target number of blocks has been removed. The RPC calls are deprecated and will either return -1 or 1e24 appropriately. The format for fee_estimates.dat has also changed to no longer save these priority estimates. It will automatically be converted to the new format which is not readable by prior versions of the software.
Support for “priority” (coin age) transaction sorting for mining is considered deprecated in Core and will be removed in the next major version. This is not to be confused with the prioritisetransaction RPC which will remain supported by Core for adding fee deltas to transactions.

P2P connection management

Peers manually added through the -addnode option or addnode RPC now have their own limit of eight connections which does not compete with other inbound or outbound connection usage and is not subject to the limitation imposed by the -maxconnections option.
New connections to manually added peers are performed more quickly.

Introduction of assumed-valid blocks

A significant portion of the initial block download time is spent verifying scripts/signatures. Although the verification must pass to ensure the security of the system, no other result from this verification is needed: If the node knew the history of a given block were valid it could skip checking scripts for its ancestors.
A new configuration option ‘assumevalid’ is provided to express this knowledge to the software. Unlike the ‘checkpoints’ in the past this setting does not force the use of a particular chain: chains that are consistent with it are processed quicker, but other chains are still accepted if they’d otherwise be chosen as best. Also unlike ‘checkpoints’ the user can configure which block history is assumed true, this means that even outdated software can sync more quickly if the setting is updated by the user.
Because the validity of a chain history is a simple objective fact it is much easier to review this setting. As a result the software ships with a default value adjusted to match the current chain shortly before release. The use of this default value can be disabled by setting -assumevalid=0

Fundrawtransaction change address reuse

Before 0.14, fundrawtransaction was by default wallet stateless. In almost all cases fundrawtransaction does add a change-output to the outputs of the funded transaction. Before 0.14, the used keypool key was never marked as change-address key and directly returned to the keypool (leading to address reuse). Before 0.14, calling getnewaddress directly after fundrawtransaction did generate the same address as the change-output address.
Since 0.14, fundrawtransaction does reserve the change-output-key from the keypool by default (optional by setting reserveChangeKey, default = true)
Users should also consider using getrawchangeaddress() in conjunction with fundrawtransaction’s changeAddress option.

Unused mempool memory used by coincache

Before 0.14, memory reserved for mempool (using the -maxmempool option) went unused during initial block download, or IBD. In 0.14, the UTXO DB cache (controlled with the -dbcache option) borrows memory from the mempool when there is extra memory available. This may result in an increase in memory usage during IBD for those previously relying on only the -dbcache option to limit memory during that time.

Aixcoin Core 0.13.2

Tue, 03 Jan 2017 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.13.2 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.13.2/

This is a new minor version release, including various bugfixes and performance improvements, as well as updated translations.

Please report bugs using the issue tracker at github:

https://github.com/aixcoin/aixcoin/issues

Compatibility

Microsoft ended support for Windows XP on April 8th, 2014, an OS initially released in 2001. This means that not even critical security updates will be released anymore. Without security updates, using a aixcoin wallet on a XP machine is irresponsible at least.

In addition to that, with 0.12.x there have been varied reports of Aixcoin Core randomly crashing on Windows XP. It is not clear what the source of these crashes is, but it is likely that upstream libraries such as Qt are no longer being tested on XP.

We do not have time nor resources to provide support for an OS that is end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are suggested to upgrade to a newer version of Windows, or install an alternative OS that is supported.

No attempt is made to prevent installing or running the software on Windows XP, you can still do so at your own risk, but do not expect it to work: do not report issues about Windows XP to the issue tracker.

From 0.13.1 onwards OS X 10.7 is no longer supported. 0.13.0 was intended to work on 10.7+, but severe issues with the libc++ version on 10.7.x keep it from running reliably. 0.13.1 now requires 10.8+, and will communicate that to 10.7 users, rather than crashing unexpectedly.

Notable changes

Change to wallet handling of mempool rejection

When a newly created transaction failed to enter the mempool due to the limits on chains of unconfirmed transactions the sending RPC calls would return an error. The transaction would still be queued in the wallet and, once some of the parent transactions were confirmed, broadcast after the software was restarted.

This behavior has been changed to return success and to reattempt mempool insertion at the same time transaction rebroadcast is attempted, avoiding a need for a restart.

Transactions in the wallet which cannot be accepted into the mempool can be abandoned with the previously existing abandontransaction RPC (or in the GUI via a context menu on the transaction).

Compatibility

Notable changes

Segregated witness soft fork

Segregated witness (segwit) is a soft fork that, if activated, will allow transaction-producing software to separate (segregate) transaction signatures (witnesses) from the part of the data in a transaction that is covered by the txid. This provides several immediate benefits:

Elimination of unwanted transaction malleability: Segregating the witness allows both existing and upgraded software to calculate the transaction identifier (txid) of transactions without referencing the witness, which can sometimes be changed by third-parties (such as miners) or by co-signers in a multisig spend. This solves all known cases of unwanted transaction malleability, which is a problem that makes programming Aixcoin wallet software more difficult and which seriously complicates the design of smart contracts for Aixcoin.
Capacity increase: Segwit transactions contain new fields that are not part of the data currently used to calculate the size of a block, which allows a block containing segwit transactions to hold more data than allowed by the current maximum block size. Estimates based on the transactions currently found in blocks indicate that if all wallets switch to using segwit, the network will be able to support about 70% more transactions. The network will also be able to support more of the advanced-style payments (such as multisig) than it can support now because of the different weighting given to different parts of a transaction after segwit activates (see the following section for details).
Weighting data based on how it affects node performance: Some parts of each Aixcoin block need to be stored by nodes in order to validate future blocks; other parts of a block can be immediately forgotten (pruned) or used only for helping other nodes sync their copy of the block chain. One large part of the immediately prunable data are transaction signatures (witnesses), and segwit makes it possible to give a different “weight” to segregated witnesses to correspond with the lower demands they place on node resources. Specifically, each byte of a segregated witness is given a weight of 1, each other byte in a block is given a weight of 4, and the maximum allowed weight of a block is 4 million. Weighting the data this way better aligns the most profitable strategy for creating blocks with the long-term costs of block validation.
Signature covers value: A simple improvement in the way signatures are generated in segwit simplifies the design of secure signature generators (such as hardware wallets), reduces the amount of data the signature generator needs to download, and allows the signature generator to operate more quickly. This is made possible by having the generator sign the amount of aixcoins they think they are spending, and by having full nodes refuse to accept those signatures unless the amount of aixcoins being spent is exactly the same as was signed. For non-segwit transactions, wallets instead had to download the complete previous transactions being spent for every payment they made, which could be a slow operation on hardware wallets and in other situations where bandwidth or computation speed was constrained.
Linear scaling of sighash operations: In 2015 a block was produced that required about 25 seconds to validate on modern hardware because of the way transaction signature hashes are performed. Other similar blocks, or blocks that could take even longer to validate, can still be produced today. The problem that caused this can’t be fixed in a soft fork without unwanted side-effects, but transactions that opt-in to using segwit will now use a different signature method that doesn’t suffer from this problem and doesn’t have any unwanted side-effects.
Increased security for multisig: Aixcoin addresses (both P2PKH addresses that start with a ‘1’ and P2SH addresses that start with a ‘3’) use a hash function known as RIPEMD-160. For P2PKH addresses, this provides about 160 bits of security—which is beyond what cryptographers believe can be broken today. But because P2SH is more flexible, only about 80 bits of security is provided per address. Although 80 bits is very strong security, it is within the realm of possibility that it can be broken by a powerful adversary. Segwit allows advanced transactions to use the SHA256 hash function instead, which provides about 128 bits of security (that is 281 trillion times as much security as 80 bits and is equivalent to the maximum bits of security believed to be provided by Aixcoin’s choice of parameters for its Elliptic Curve Digital Security Algorithm [ECDSA].)
More efficient almost-full-node security Satoshi Nakamoto’s original Aixcoin paper describes a method for allowing newly-started full nodes to skip downloading and validating some data from historic blocks that are protected by large amounts of proof of work. Unfortunately, Nakamoto’s method can’t guarantee that a newly-started node using this method will produce an accurate copy of Aixcoin’s current ledger (called the UTXO set), making the node vulnerable to falling out of consensus with other nodes. Although the problems with Nakamoto’s method can’t be fixed in a soft fork, Segwit accomplishes something similar to his original proposal: it makes it possible for a node to optionally skip downloading some blockchain data (specifically, the segregated witnesses) while still ensuring that the node can build an accurate copy of the UTXO set for the block chain with the most proof of work. Segwit enables this capability at the consensus layer, but note that Aixcoin Core does not provide an option to use this capability as of this 0.13.1 release.
Script versioning: Segwit makes it easy for future soft forks to allow Aixcoin users to individually opt-in to almost any change in the Aixcoin Script language when those users receive new transactions. Features currently being researched by Aixcoin Core contributors that may use this capability include support for Schnorr signatures, which can improve the privacy and efficiency of multisig transactions (or transactions with multiple inputs), and Merklized Abstract Syntax Trees (MAST), which can improve the privacy and efficiency of scripts with two or more conditions. Other Aixcoin community members are studying several other improvements that can be made using script versioning.

Activation for the segwit soft fork is being managed using BIP9 versionbits. Segwit’s version bit is bit 1, and nodes will begin tracking which blocks signal support for segwit at the beginning of the first retarget period after segwit’s start date of 15 November 2016. If 95% of blocks within a 2,016-block retarget period (about two weeks) signal support for segwit, the soft fork will be locked in. After another 2,016 blocks, segwit will activate.

For more information about segwit, please see the segwit FAQ, the segwit wallet developers guide or BIPs 141, 143, 144, and 145. If you’re a miner or mining pool operator, please see the versionbits FAQ for information about signaling support for a soft fork.

Null dummy soft fork

Combined with the segwit soft fork is an additional change that turns a long-existing network relay policy into a consensus rule. The OP_CHECKMULTISIG and OP_CHECKMULTISIGVERIFY opcodes consume an extra stack element (“dummy element”) after signature validation. The dummy element is not inspected in any manner, and could be replaced by any value without invalidating the script.

Because any value can be used for this dummy element, it’s possible for a third-party to insert data into other people’s transactions, changing the transaction’s txid (called transaction malleability) and possibly causing other problems.

Since Aixcoin Core 0.10.0, nodes have defaulted to only relaying and mining transactions whose dummy element was a null value (0x00, also called OP_0). The null dummy soft fork turns this relay rule into a consensus rule both for non-segwit transactions and segwit transactions, so that this method of mutating transactions is permanently eliminated from the network.

Signaling for the null dummy soft fork is done by signaling support for segwit, and the null dummy soft fork will activate at the same time as segwit.

For more information, please see BIP147.

Low-level RPC changes

importprunedfunds only accepts two required arguments. Some versions accept an optional third arg, which was always ignored. Make sure to never pass more than two arguments.

Linux ARM builds

With the 0.13.0 release, pre-built Linux ARM binaries were added to the set of uploaded executables. Additional detail on the ARM architecture targeted by each is provided below.

The following extra files can be found in the download directory or torrent:

aixcoin-${VERSION}-arm-linux-gnueabihf.tar.gz: Linux binaries targeting the 32-bit ARMv7-A architecture.
aixcoin-${VERSION}-aarch64-linux-gnu.tar.gz: Linux binaries targeting the 64-bit ARMv8-A architecture.

ARM builds are still experimental. If you have problems on a certain device or Linux distribution combination please report them on the bug tracker, it may be possible to resolve them. Note that the device you use must be (backward) compatible with the architecture targeted by the binary that you use. For example, a Raspberry Pi 2 Model B or Raspberry Pi 3 Model B (in its 32-bit execution state) device, can run the 32-bit ARMv7-A targeted binary. However, no model of Raspberry Pi 1 device can run either binary because they are all ARMv6 architecture devices that are not compatible with ARMv7-A or ARMv8-A.

Note that Android is not considered ARM Linux in this context. The executables are not expected to work out of the box on Android.

Compatibility

We do not have time nor resources to provide support for an OS that is end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are suggested to upgrade to a newer verion of Windows, or install an alternative OS that is supported.

Notable changes

Database cache memory increased

As a result of growth of the UTXO set, performance with the prior default database cache of 100 MiB has suffered. For this reason the default was changed to 300 MiB in this release.

For nodes on low-memory systems, the database cache can be changed back to 100 MiB (or to another value) by either:

Adding dbcache=100 in aixcoin.conf
Changing it in the GUI under Options → Size of database cache

Note that the database cache setting has the most performance impact during initial sync of a node, and when catching up after downtime.

aixcoin-cli: arguments privacy

The RPC command line client gained a new argument, -stdin to read extra arguments from standard input, one per line until EOF/Ctrl-D. For example:

$ src/aixcoin-cli -stdin walletpassphrase
mysecretcode
120
..... press Ctrl-D here to end input
$

It is recommended to use this for sensitive information such as wallet passphrases, as command-line arguments can usually be read from the process table by any user on the system.

C++11 and Python 3

Various code modernizations have been done. The Aixcoin Core code base has started using C++11. This means that a C++11-capable compiler is now needed for building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher.

When cross-compiling for a target that doesn’t have C++11 libraries, configure with ./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++.

For running the functional tests in qa/rpc-tests, Python3.4 or higher is now required.

Linux ARM builds

Due to popular request, Linux ARM builds have been added to the uploaded executables.

The following extra files can be found in the download directory or torrent:

aixcoin-${VERSION}-arm-linux-gnueabihf.tar.gz: Linux binaries for the most common 32-bit ARM architecture.
aixcoin-${VERSION}-aarch64-linux-gnu.tar.gz: Linux binaries for the most common 64-bit ARM architecture.

ARM builds are still experimental. If you have problems on a certain device or Linux distribution combination please report them on the bug tracker, it may be possible to resolve them.

Note that Android is not considered ARM Linux in this context. The executables are not expected to work out of the box on Android.

Compact Block support (BIP 152)

Support for block relay using the Compact Blocks protocol has been implemented in PR 8068.

The primary goal is reducing the bandwidth spikes at relay time, though in many cases it also reduces propagation delay. It is automatically enabled between compatible peers. BIP 152

As a side-effect, ordinary non-mining nodes will download and upload blocks faster if those blocks were produced by miners using similar transaction filtering policies. This means that a miner who produces a block with many transactions discouraged by your node will be relayed slower than one with only transactions already in your memory pool. The overall effect of such relay differences on the network may result in blocks which include widely- discouraged transactions losing a stale block race, and therefore miners may wish to configure their node to take common relay policies into consideration.

Hierarchical Deterministic Key Generation

Newly created wallets will use hierarchical deterministic key generation according to BIP32 (keypath m/0’/0’/k’). Existing wallets will still use traditional key generation.

Backups of HD wallets, regardless of when they have been created, can therefore be used to re-generate all possible private keys, even the ones which haven’t already been generated during the time of the backup. Attention: Encrypting the wallet will create a new seed which requires a new backup!

Wallet dumps (created using the dumpwallet RPC) will contain the deterministic seed. This is expected to allow future versions to import the seed and all associated funds, but this is not yet implemented.

HD key generation for new wallets can be disabled by -usehd=0. Keep in mind that this flag only has affect on newly created wallets. You can’t disable HD key generation once you have created a HD wallet.

There is no distinction between internal (change) and external keys.

HD wallets are incompatible with older versions of Aixcoin Core.

Pull request, BIP 32

Segregated Witness

The code preparations for Segregated Witness (“segwit”), as described in BIP 141, BIP 143, BIP 144, and BIP 145 are finished and included in this release. However, BIP 141 does not yet specify activation parameters on mainnet, and so this release does not support segwit use on mainnet. Testnet use is supported, and after BIP 141 is updated with proposed parameters, a future release of Aixcoin Core is expected that implements those parameters for mainnet.

Furthermore, because segwit activation is not yet specified for mainnet, version 0.13.0 will behave similarly as other pre-segwit releases even after a future activation of BIP 141 on the network. Upgrading from 0.13.0 will be required in order to utilize segwit-related features on mainnet (such as signal BIP 141 activation, mine segwit blocks, fully validate segwit blocks, relay segwit blocks to other segwit nodes, and use segwit transactions in the wallet, etc).

Mining transaction selection (“Child Pays For Parent”)

The mining transaction selection algorithm has been replaced with an algorithm that selects transactions based on their feerate inclusive of unconfirmed ancestor transactions. This means that a low-fee transaction can become more likely to be selected if a high-fee transaction that spends its outputs is relayed.

With this change, the -blockminsize command line option has been removed.

The command line option -blockmaxsize remains an option to specify the maximum number of serialized bytes in a generated block. In addition, the new command line option -blockmaxweight has been added, which specifies the maximum “block weight” of a generated block, as defined by [BIP 141 (Segregated Witness)] (https://github.com/aixcoin/bips/blob/master/bip-0141.mediawiki).

In preparation for Segregated Witness, the mining algorithm has been modified to optimize transaction selection for a given block weight, rather than a given number of serialized bytes in a block. In this release, transaction selection is unaffected by this distinction (as BIP 141 activation is not supported on mainnet in this release, see above), but in future releases and after BIP 141 activation, these calculations would be expected to differ.

For optimal runtime performance, miners using this release should specify -blockmaxweight on the command line, and not specify -blockmaxsize. Additionally (or only) specifying -blockmaxsize, or relying on default settings for both, may result in performance degradation, as the logic to support -blockmaxsize performs additional computation to ensure that constraint is met. (Note that for mainnet, in this release, the equivalent parameter for -blockmaxweight would be four times the desired -blockmaxsize. See [BIP 141] (https://github.com/aixcoin/bips/blob/master/bip-0141.mediawiki) for additional details.)

In the future, the -blockmaxsize option may be removed, as block creation is no longer optimized for this metric. Feedback is requested on whether to deprecate or keep this command line option in future releases.

Reindexing changes

In earlier versions, reindexing did validation while reading through the block files on disk. These two have now been split up, so that all blocks are known before validation starts. This was necessary to make certain optimizations that are available during normal synchronizations also available during reindexing.

The two phases are distinct in the Aixcoin-Qt GUI. During the first one, “Reindexing blocks on disk” is shown. During the second (slower) one, “Processing blocks on disk” is shown.

It is possible to only redo validation now, without rebuilding the block index, using the command line option -reindex-chainstate (in addition to -reindex which does both). This new option is useful when the blocks on disk are assumed to be fine, but the chainstate is still corrupted. It is also useful for benchmarks.

Removal of internal miner

As CPU mining has been useless for a long time, the internal miner has been removed in this release, and replaced with a simpler implementation for the test framework.

The overall result of this is that setgenerate RPC call has been removed, as well as the -gen and -genproclimit command-line options.

For testing, the generate call can still be used to mine a block, and a new RPC call generatetoaddress has been added to mine to a specific address. This works with wallet disabled.

New bytespersigop implementation

The former implementation of the bytespersigop filter accidentally broke bare multisig (which is meant to be controlled by the permitbaremultisig option), since the consensus protocol always counts these older transaction forms as 20 sigops for backwards compatibility. Simply fixing this bug by counting more accurately would have reintroduced a vulnerability. It has therefore been replaced with a new implementation that rather than filter such transactions, instead treats them (for fee purposes only) as if they were in fact the size of a transaction actually using all 20 sigops.

Low-level P2P changes

The optional new p2p message “feefilter” is implemented and the protocol version is bumped to 70013. Upon receiving a feefilter message from a peer, a node will not send invs for any transactions which do not meet the filter feerate. BIP 133
The P2P alert system has been removed in PR #7692 and the alert P2P message is no longer supported.
The transaction relay mechanism used to relay one quarter of all transactions instantly, while queueing up the rest and sending them out in batch. As this resulted in chains of dependent transactions being reordered, it systematically hurt transaction relay. The relay code was redesigned in PRs <a href=”https://github.com/aixcoin/aixcoin/pull/7840”>#7840</a> and #8082, and now always batches transactions announcements while also sorting them according to dependency order. This significantly reduces orphan transactions. To compensate for the removal of instant relay, the frequency of batch sending was doubled for outgoing peers.
Since PR #7840 the BIP35 mempool command is also subject to batch processing. Also the mempool message is no longer handled for non-whitelisted peers when NODE_BLOOM is disabled through -peerbloomfilters=0.
The maximum size of orphan transactions that are kept in memory until their ancestors arrive has been raised in PR #8179 from 5000 to 99999 bytes. They are now also removed from memory when they are included in a block, conflict with a block, and time out after 20 minutes.
We respond at most once to a getaddr request during the lifetime of a connection since PR #7856.
Connections to peers who have recently been the first one to give us a valid new block or transaction are protected from disconnections since PR #8084.

Low-level RPC changes

RPC calls have been added to output detailed statistics for individual mempool entries, as well as to calculate the in-mempool ancestors or descendants of a transaction: see getmempoolentry, getmempoolancestors, getmempooldescendants.
gettxoutsetinfo UTXO hash (hash_serialized) has changed. There was a divergence between 32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been fixed, but this means that the output will be different than from previous versions.
Full UTF-8 support in the RPC API. Non-ASCII characters in, for example, wallet labels have always been malformed because they weren’t taken into account properly in JSON RPC processing. This is no longer the case. This also affects the GUI debug console.
Asm script outputs replacements for OP_NOP2 and OP_NOP3
- OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by BIP 65
- OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by BIP 112
- The following outputs are affected by this change:
  - RPC getrawtransaction (in verbose mode)
  - RPC decoderawtransaction
  - RPC decodescript
  - REST /rest/tx/ (JSON format)
  - REST /rest/block/ (JSON format when including extended tx details)
  - aixcoin-tx -json
The sorting of the output of the getrawmempool output has changed.
New RPC commands: generatetoaddress, importprunedfunds, removeprunedfunds, signmessagewithprivkey, getmempoolancestors, getmempooldescendants, getmempoolentry, createwitnessaddress, addwitnessaddress.
Removed RPC commands: setgenerate, getgenerate.
New options were added to fundrawtransaction: includeWatching, changeAddress, changePosition and feeRate.

Low-level ZMQ changes

Each ZMQ notification now contains an up-counting sequence number that allows listeners to detect lost notifications. The sequence number is always the last element in a multi-part ZMQ notification and therefore backward compatible. Each message type has its own counter. PR #7762.

Aixcoin Core 0.12.1

Fri, 15 Apr 2016 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.12.1 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.12.1/

This is a new minor version release, including the BIP9, BIP68 and BIP112 softfork, various bugfixes and updated translations.

Please report bugs using the issue tracker at github:

https://github.com/aixcoin/aixcoin/issues

Upgrading and downgrading

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Aixcoin-Qt (on Mac) or aixcoind/aixcoin-qt (on Linux).

Downgrade warning

Downgrade to a version < 0.12.0

Because release 0.12.0 and later will obfuscate the chainstate on every fresh sync or reindex, the chainstate is not backwards-compatible with pre-0.12 versions of Aixcoin Core or other software.

If you want to downgrade after you have done a reindex with 0.12.0 or later, you will need to reindex when you first start Aixcoin Core version 0.11 or earlier.

Notable changes

First version bits BIP9 softfork deployment

This release includes a soft fork deployment to enforce BIP68, BIP112 and BIP113 using the BIP9 deployment mechanism.

The deployment sets the block version number to 0x20000001 between midnight 1st May 2016 and midnight 1st May 2017 to signal readiness for deployment. The version number consists of 0x20000000 to indicate version bits together with setting bit 0 to indicate support for this combined deployment, shown as “csv” in the getblockchaininfo RPC call.

For more information about the soft forking change, please see https://github.com/aixcoin/aixcoin/pull/7648

This specific backport pull-request can be viewed at https://github.com/aixcoin/aixcoin/pull/7543

BIP68 soft fork to enforce sequence locks for relative locktime

BIP68 introduces relative lock-time consensus-enforced semantics of the sequence number field to enable a signed transaction input to remain invalid for a defined period of time after confirmation of its corresponding outpoint.

For more information about the implementation, see https://github.com/aixcoin/aixcoin/pull/7184

BIP112 soft fork to enforce OP_CHECKSEQUENCEVERIFY

BIP112 redefines the existing OP_NOP3 as OP_CHECKSEQUENCEVERIFY (CSV) for a new opcode in the Aixcoin scripting system that in combination with BIP68 allows execution pathways of a script to be restricted based on the age of the output being spent.

For more information about the implementation, see https://github.com/aixcoin/aixcoin/pull/7524

BIP113 locktime enforcement soft fork

Aixcoin Core 0.11.2 previously introduced mempool-only locktime enforcement using GetMedianTimePast(). This release seeks to consensus enforce the rule.

Aixcoin transactions currently may specify a locktime indicating when they may be added to a valid block. Current consensus rules require that blocks have a block header time greater than the locktime specified in any transaction in that block.

Miners get to choose what time they use for their header time, with the consensus rule being that no node will accept a block whose time is more than two hours in the future. This creates a incentive for miners to set their header times to future values in order to include locktimed transactions which weren’t supposed to be included for up to two more hours.

The consensus rules also specify that valid blocks may have a header time greater than that of the median of the 11 previous blocks. This GetMedianTimePast() time has a key feature we generally associate with time: it can’t go backwards.

BIP113 specifies a soft fork enforced in this release that weakens this perverse incentive for individual miners to use a future time by requiring that valid blocks have a computed GetMedianTimePast() greater than the locktime specified in any transaction in that block.

Mempool inclusion rules currently require transactions to be valid for immediate inclusion in a block in order to be accepted into the mempool. This release begins applying the BIP113 rule to received transactions, so transaction whose time is greater than the GetMedianTimePast() will no longer be accepted into the mempool.

Implication for miners: you will begin rejecting transactions that would not be valid under BIP113, which will prevent you from producing invalid blocks when BIP113 is enforced on the network. Any transactions which are valid under the current rules but not yet valid under the BIP113 rules will either be mined by other miners or delayed until they are valid under BIP113. Note, however, that time-based locktime transactions are more or less unseen on the network currently.

Implication for users: GetMedianTimePast() always trails behind the current time, so a transaction locktime set to the present time will be rejected by nodes running this release until the median time moves forward. To compensate, subtract one hour (3,600 seconds) from your locktimes to allow those transactions to be included in mempools at approximately the expected time.

Aixcoin Core 0.12.0

Tue, 23 Feb 2016 00:00:00 +0000

Aixcoin Core installation binaries can be downloaded from aixcoin-core.github.io and the source-code is available from the Aixcoin Core source repository.

Aixcoin Core version 0.12.0 is now available from:

https://aixcoin-core.github.io/bin/aixcoin-core-0.12.0/

This is a new major version release, bringing new features and other improvements.

Please report bugs using the issue tracker at github:

https://github.com/aixcoin/aixcoin/issues

Upgrading and downgrading

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Aixcoin-Qt (on Mac) or aixcoind/aixcoin-qt (on Linux).

Downgrade warning

Downgrade to a version < 0.10.0

Because release 0.10.0 and later makes use of headers-first synchronization and parallel block download (see further), the block files and databases are not backwards-compatible with pre-0.10 versions of Aixcoin Core or other software:

Blocks will be stored on disk out of order (in the order they are received, really), which makes it incompatible with some tools or other programs. Reindexing using earlier versions will also not work anymore as a result of this.
The block index database will now hold headers for which no block is stored on disk, which earlier versions won’t support.

If you want to be able to downgrade smoothly, make a backup of your entire data directory. Without this your node will need start syncing (or importing from bootstrap.dat) anew afterwards. It is possible that the data from a completely synchronised 0.10 node may be usable in older versions as-is, but this is not supported and may break as soon as the older version attempts to reindex.

This does not affect wallet forward or backward compatibility.

Downgrade to a version < 0.12.0

Because release 0.12.0 and later will obfuscate the chainstate on every fresh sync or reindex, the chainstate is not backwards-compatible with pre-0.12 versions of Aixcoin Core or other software.

If you want to downgrade after you have done a reindex with 0.12.0 or later, you will need to reindex when you first start Aixcoin Core version 0.11 or earlier.

Notable changes

Signature validation using libsecp256k1

ECDSA signatures inside Aixcoin transactions now use validation using libsecp256k1 instead of OpenSSL.

Depending on the platform, this means a significant speedup for raw signature validation speed. The advantage is largest on x86_64, where validation is over five times faster. In practice, this translates to a raw reindexing and new block validation times that are less than half of what it was before.

Libsecp256k1 has undergone very extensive testing and validation.

A side effect of this change is that libconsensus no longer depends on OpenSSL.

Reduce upload traffic

A major part of the outbound traffic is caused by serving historic blocks to other nodes in initial block download state.

It is now possible to reduce the total upload traffic via the -maxuploadtarget parameter. This is not a hard limit but a threshold to minimize the outbound traffic. When the limit is about to be reached, the uploaded data is cut by not serving historic blocks (blocks older than one week). Moreover, any SPV peer is disconnected when they request a filtered block.

This option can be specified in MiB per day and is turned off by default (-maxuploadtarget=0). The recommended minimum is 144 * MAX_BLOCK_SIZE (currently 144MB) per day.

Whitelisted peers will never be disconnected, although their traffic counts for calculating the target.

A more detailed documentation about keeping traffic low can be found in /doc/reduce-traffic.md.

Direct headers announcement (BIP 130)

Between compatible peers, BIP 130 direct headers announcement is used. This means that blocks are advertised by announcing their headers directly, instead of just announcing the hash. In a reorganization, all new headers are sent, instead of just the new tip. This can often prevent an extra roundtrip before the actual block is downloaded.

With this change, pruning nodes are now able to relay new blocks to compatible peers.

Memory pool limiting

Previous versions of Aixcoin Core had their mempool limited by checking a transaction’s fees against the node’s minimum relay fee. There was no upper bound on the size of the mempool and attackers could send a large number of transactions paying just slighly more than the default minimum relay fee to crash nodes with relatively low RAM. A temporary workaround for previous versions of Aixcoin Core was to raise the default minimum relay fee.

Aixcoin Core 0.12 will have a strict maximum size on the mempool. The default value is 300 MB and can be configured with the -maxmempool parameter. Whenever a transaction would cause the mempool to exceed its maximum size, the transaction that (along with in-mempool descendants) has the lowest total feerate (as a package) will be evicted and the node’s effective minimum relay feerate will be increased to match this feerate plus the initial minimum relay feerate. The initial minimum relay feerate is set to 1000 satoshis per kB.

Aixcoin Core 0.12 also introduces new default policy limits on the length and size of unconfirmed transaction chains that are allowed in the mempool (generally limiting the length of unconfirmed chains to 25 transactions, with a total size of 101 KB). These limits can be overriden using command line arguments; see the extended help (--help -help-debug) for more information.

Opt-in Replace-by-fee transactions

It is now possible to replace transactions in the transaction memory pool of Aixcoin Core 0.12 nodes. Aixcoin Core will only allow replacement of transactions which have any of their inputs’ nSequence number set to less than 0xffffffff - 1. Moreover, a replacement transaction may only be accepted when it pays sufficient fee, as described in BIP 125.

Transaction replacement can be disabled with a new command line option, -mempoolreplacement=0. Transactions signaling replacement under BIP125 will still be allowed into the mempool in this configuration, but replacements will be rejected. This option is intended for miners who want to continue the transaction selection behavior of previous releases.

The -mempoolreplacement option is not recommended for wallet users seeking to avoid receipt of unconfirmed opt-in transactions, because this option does not prevent transactions which are replaceable under BIP 125 from being accepted (only subsequent replacements, which other nodes on the network that implement BIP 125 are likely to relay and mine). Wallet users wishing to detect whether a transaction is subject to replacement under BIP 125 should instead use the updated RPC calls gettransaction and listtransactions, which now have an additional field in the output indicating if a transaction is replaceable under BIP125 (“bip125-replaceable”).

Note that the wallet in Aixcoin Core 0.12 does not yet have support for creating transactions that would be replaceable under BIP 125.

When no -rpcpassword is specified, the daemon now uses a special ‘cookie’ file for authentication. This file is generated with random content when the daemon starts, and deleted when it exits. Its contents are used as authentication token. Read access to this file controls who can access through RPC. By default it is stored in the data directory but its location can be overridden with the option -rpccookiefile.

This is similar to Tor’s CookieAuthentication: see https://www.torproject.org/docs/tor-manual.html.en

This allows running aixcoind without having to do any manual configuration.

Relay: Any sequence of pushdatas in OP_RETURN outputs now allowed

Previously OP_RETURN outputs with a payload were only relayed and mined if they had a single pushdata. This restriction has been lifted to allow any combination of data pushes and numeric constant opcodes (OP_1 to OP_16) after the OP_RETURN. The limit on OP_RETURN output size is now applied to the entire serialized scriptPubKey, 83 bytes by default. (the previous 80 byte default plus three bytes overhead)

Relay and Mining: Priority transactions

Aixcoin Core has a heuristic ‘priority’ based on coin value and age. This calculation is used for relaying of transactions which do not pay the minimum relay fee, and can be used as an alternative way of sorting transactions for mined blocks. Aixcoin Core will relay transactions with insufficient fees depending on the setting of -limitfreerelay=<r> (default: r=15 kB per minute) and -blockprioritysize=<s>.

In Aixcoin Core 0.12, when mempool limit has been reached a higher minimum relay fee takes effect to limit memory usage. Transactions which do not meet this higher effective minimum relay fee will not be relayed or mined even if they rank highly according to the priority heuristic.

The mining of transactions based on their priority is also now disabled by default. To re-enable it, simply set -blockprioritysize=<n> where is the size in bytes of your blocks to reserve for these transactions. The old default was 50k, so to retain approximately the same policy, you would set -blockprioritysize=50000.

Additionally, as a result of computational simplifications, the priority value used for transactions received with unconfirmed inputs is lower than in prior versions due to avoiding recomputing the amounts as input transactions confirm.

External miner policy set via the prioritisetransaction RPC to rank transactions already in the mempool continues to work as it has previously. Note, however, that if mining priority transactions is left disabled, the priority delta will be ignored and only the fee metric will be effective.

This internal automatic prioritization handling is being considered for removal entirely in Aixcoin Core 0.13, and it is at this time undecided whether the more accurate priority calculation for chained unconfirmed transactions will be restored. Community direction on this topic is particularly requested to help set project priorities.

Automatically use Tor hidden services

Starting with Tor version 0.2.7.1 it is possible, through Tor’s control socket API, to create and destroy ‘ephemeral’ hidden services programmatically. Aixcoin Core has been updated to make use of this.

This means that if Tor is running (and proper authorization is available), Aixcoin Core automatically creates a hidden service to listen on, without manual configuration. Aixcoin Core will also use Tor automatically to connect to other .onion nodes if the control socket can be successfully opened. This will positively affect the number of available .onion nodes and their usage.

This new feature is enabled by default if Aixcoin Core is listening, and a connection to Tor can be made. It can be configured with the -listenonion, -torcontrol and -torpassword settings. To show verbose debugging information, pass -debug=tor.

Notifications through ZMQ

Aixcoind can now (optionally) asynchronously notify clients through a ZMQ-based PUB socket of the arrival of new transactions and blocks. This feature requires installation of the ZMQ C API library 4.x and configuring its use through the command line or configuration file. Please see docs/zmq.md for details of operation.

Wallet: Transaction fees

Various improvements have been made to how the wallet calculates transaction fees.

Users can decide to pay a predefined fee rate by setting -paytxfee=<n> (or settxfee <n> rpc during runtime). A value of n=0 signals Aixcoin Core to use floating fees. By default, Aixcoin Core will use floating fees.

Based on past transaction data, floating fees approximate the fees required to get into the mth block from now. This is configurable with -txconfirmtarget=<m> (default: 2).

Sometimes, it is not possible to give good estimates, or an estimate at all. Therefore, a fallback value can be set with -fallbackfee=<f> (default: 0.0002 AIX/kB).

At all times, Aixcoin Core will cap fees at -maxtxfee=<x> (default: 0.10) AIX. Furthermore, Aixcoin Core will never create transactions paying less than the current minimum relay fee. Finally, a user can set the minimum fee rate for all transactions with -mintxfee=<i>, which defaults to 1000 satoshis per kB.

Wallet: Negative confirmations and conflict detection

The wallet will now report a negative number for confirmations that indicates how deep in the block chain the conflict is found. For example, if a transaction A has 5 confirmations and spends the same input as a wallet transaction B, B will be reported as having -5 confirmations. If another wallet transaction C spends an output from B, it will also be reported as having -5 confirmations. To detect conflicts with historical transactions in the chain a one-time -rescan may be needed.

Unlike earlier versions, unconfirmed but non-conflicting transactions will never get a negative confirmation count. They are not treated as spendable unless they’re coming from ourself (change) and accepted into our local mempool, however. The new “trusted” field in the listtransactions RPC output indicates whether outputs of an unconfirmed transaction are considered spendable.

Wallet: Merkle branches removed

Previously, every wallet transaction stored a Merkle branch to prove its presence in blocks. This wasn’t being used for more than an expensive sanity check. Since 0.12, these are no longer stored. When loading a 0.12 wallet into an older version, it will automatically rescan to avoid failed checks.

Wallet: Pruning

With 0.12 it is possible to use wallet functionality in pruned mode. This can reduce the disk usage from currently around 60 GB to around 2 GB.

However, rescans as well as the RPCs importwallet, importaddress, importprivkey are disabled.

To enable block pruning set prune=<N> on the command line or in aixcoin.conf, where N is the number of MiB to allot for raw block & undo data.

A value of 0 disables pruning. The minimal value above 0 is 550. Your wallet is as secure with high values as it is with low ones. Higher values merely ensure that your node will not shut down upon blockchain reorganizations of more than 2 days - which are unlikely to happen in practice. In future releases, a higher value may also help the network as a whole: stored blocks could be served to other nodes.

For further information about pruning, you may also consult the release notes of v0.11.0.

`NODE_BLOOM` service bit

Support for the NODE_BLOOM service bit, as described in BIP 111, has been added to the P2P protocol code.

BIP 111 defines a service bit to allow peers to advertise that they support bloom filters (such as used by SPV clients) explicitly. It also bumps the protocol version to allow peers to identify old nodes which allow bloom filtering of the connection despite lacking the new service bit.

In this version, it is only enforced for peers that send protocol versions >=70011. For the next major version it is planned that this restriction will be removed. It is recommended to update SPV clients to check for the NODE_BLOOM service bit for nodes that report versions newer than 70011.

Option parsing behavior

Command line options are now parsed strictly in the order in which they are specified. It used to be the case that -X -noX ends up, unintuitively, with X set, as -X had precedence over -noX. This is no longer the case. Like for other software, the last specified value for an option will hold.

RPC: Low-level API changes

Monetary amounts can be provided as strings. This means that for example the argument to sendtoaddress can be “0.0001” instead of 0.0001. This can be an advantage if a JSON library insists on using a lossy floating point type for numbers, which would be dangerous for monetary amounts.
The asm property of each scriptSig now contains the decoded signature hash type for each signature that provides a valid defined hash type.
OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by BIP 65

The following items contain assembly representations of scriptSig signatures and are affected by this change:

RPC getrawtransaction
RPC decoderawtransaction
RPC decodescript
REST /rest/tx/ (JSON format)
REST /rest/block/ (JSON format when including extended tx details)
aixcoin-tx -json

For example, the scriptSig.asm property of a transaction input that previously showed an assembly representation of:

304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c509001 400000 OP_NOP2

now shows as:

304502207fa7a6d1e0ee81132a269ad84e68d695483745cde8b541e3bf630749894e342a022100c1f7ab20e13e22fb95281a870f3dcf38d782e53023ee313d741ad0cfbc0c5090[ALL] 400000 OP_CHECKLOCKTIMEVERIFY

Note that the output of the RPC decodescript did not change because it is configured specifically to process scriptPubKey and not scriptSig scripts.

RPC: SSL support dropped

SSL support for RPC, previously enabled by the option rpcssl has been dropped from both the client and the server. This was done in preparation for removing the dependency on OpenSSL for the daemon completely.

Trying to use rpcssl will result in an error:

Error: SSL mode for RPC (-rpcssl) is no longer supported.

If you are one of the few people that relies on this feature, a flexible migration path is to use stunnel. This is an utility that can tunnel arbitrary TCP connections inside SSL. On e.g. Ubuntu it can be installed with:

sudo apt-get install stunnel4

Then, to tunnel a SSL connection on 28332 to a RPC server bound on localhost on port 18332 do:

stunnel -d 28332 -r 127.0.0.1:18332 -p stunnel.pem -P ''

It can also be set up system-wide in inetd style.

Another way to re-attain SSL would be to setup a httpd reverse proxy. This solution would allow the use of different authentication, loadbalancing, on-the-fly compression and caching. A sample config for apache2 could look like:

Listen 443

NameVirtualHost *:443
<VirtualHost *:443>

SSLEngine On
SSLCertificateFile /etc/apache2/ssl/server.crt
SSLCertificateKeyFile /etc/apache2/ssl/server.key

<Location /aixcoinrpc>
    ProxyPass http://127.0.0.1:8332/
    ProxyPassReverse http://127.0.0.1:8332/
    # optional enable digest auth
    # AuthType Digest
    # ...

    # optional bypass aixcoind rpc basic auth
    # RequestHeader set Authorization "Basic <hash>"
    # get the <hash> from the shell with: base64 <<< aixcoinrpc:<password>
</Location>

# Or, balance the load:
# ProxyPass / balancer://balancer_cluster_name

</VirtualHost>

Mining Code Changes

The mining code in 0.12 has been optimized to be significantly faster and use less memory. As part of these changes, consensus critical calculations are cached on a transaction’s acceptance into the mempool and the mining code now relies on the consistency of the mempool to assemble blocks. However all blocks are still tested for validity after assembly.

Other P2P Changes

The list of banned peers is now stored on disk rather than in memory. Restarting aixcoind will no longer clear out the list of banned peers; instead a new RPC call (clearbanned) can be used to manually clear the list. The new setban RPC call can also be used to manually ban or unban a peer.
