Release Notes for Bitcoin Cash Node version 23.0.0

Bitcoin Cash Node version 23.0.0 is now available from:


This is a major release of Bitcoin Cash Node (BCHN) that implements the May 15, 2021 Network Upgrade. This upgrade will remove the unconfirmed chain limit and enable transactions with multiple OP_RETURN outputs.

This version contains many corrections and improvements, such as:

  • Introducing the Double Spend Proof (beta) feature compatible with other clients
  • Removing the limits on number of unconfirmed ancestors and descendants, and the limits on the byte size of these chains
  • Raising the default soft limit for block generation to 8MB
  • Adding support for multiple OP_RETURN standardness (within existing data carrier size)
  • Removal of CPFP functionality
  • Changes in mempool eviction order
  • New ZMQ functionality (related to dsproof)
  • Minor RPC additions and changes (incl. dsproof related)
  • Minor changes in error codes
  • Improving the graphical user interface
  • Extension of software expiry timeframe (to 15 May 2022)
  • Switch from C++14 to C++17

Users who are running any of our previous releases (0.22.x) are urged to upgrade to v23.0.0 ahead of May 2021.

Usage recommendations

The update to Bitcoin Cash Node 23.0.0 is required for the May 15, 2021 Bitcoin Cash network upgrade.

About the CPFP & unconfirmed chain limit removal

The CPFP (child-pays-for-parent) and the unconfirmed transaction chain limit will both be deactivated on May 15, 2021 when MTP of the chain tip reaches 12:00 UTC. After that time, it will be possible to "chain" unconfirmed transactions beyond the current limit of 50, in a limitless way, without any negative performance consequence for the node.

This has been accomplished by removing the algorithmically complex and slow code we inherited from Bitcoin Core which tries to maintain what is known as "Child Pays for Parent" (CPFP) -- a way in which a child transaction can bump up the priority of its parent transaction via paying a larger fee. Maintaining this feature, which is not even being used on BCH, was the reason for the algorithmic complexity in the mempool code and why we had a limit of 50 for unconfirmed tx chains.

Additionally, we removed a lot of the slow "quadratic" (complex) per-tx stats that were being maintained (also inherited from Core, and also used in fee calculations). Removing those stats, which only were added so that Core could limit the blocksize and also get a hyper-fee-market, allowed us to unleash the true scalability of BCH. The mempool code was slow -- and it was only slow because of Bitcoin Core's philosophy about what Bitcoin should be.

One might wonder if allowing limitless unconfirmed transaction chains opens up avenues of attack or flood/DoS. It does not do this. Since now our mempool and mining algorithm is linear and not quadratic, there is no real difference between a transaction that has an unconfirmed parent and one that does not. They both now cost the same amount of CPU time to process (and in some cases the unconfirmed parent tx is actually faster to process due to not needing to hit the UTXO db).

Should some user perform a (costly) attack and flood the network with unconfirmed tx chains, the only consequence will be that he will drain his own resources in fees. Under mempool pressure, normal fee bump logic occurs. Transactions get evicted in a "lowest fee first" order and then the mempool's minimum fee for acceptance is bumped up by some small increment. This logic has always been in place and is the way we prevent floods.

In summary, removing the unconfirmed tx chain limit does not impact performance and/or availability whether under normal usage or under congestion.

Network changes

The dsproof-beta network message can be emitted and relayed when Double Spend Proofs are enabled (which they are by default).

For miners/pools running without a blockmaxsize configuration, the default soft limit of generated blocks will increase from 2MB to 8MB in this update. The default hard limit of 32MB remains unchanged in this release.

Added functionality

Double Spend Proofs (DSProof)

This release adds Double Spend Proofs that are compatible with the published dsproof-beta message specification and existing implementations in Bitcoin Unlimited and Flowee The Hub.

Double spend proofs are enabled by default, but can be turned off with the doublespendproof=0 configuration setting.

This functionality is still in beta. In future BCHN releases we plan to gradually add more application interfaces to query double spend proof information about transactions and to provide wallet user with double spend notifications.

Please refer to for more information details on the DSProof implementation in BCHN, and the sections on New RPC methods and New ZeroMQ notifications below for a listing of the new API calls.

maxgbttime and maxinitialgbttime configuration options

These two new command-line options may be of interest to miners (pools). They enable setting maximum time limits for getblocktemplate calls, instead of relying on blockmaxsize limits to limit the time taken to construct a template.

The -maxinitialgbttime setting determines the maximum number of milliseconds that can be spent adding transactions to block templates for the first template after an UpdateTip, whereas the -maxgbttime setting does the same thing but for all block templates (not just the first).

This should allow pools to create larger block sizes on average without taking on significantly greater costs and risks.

The default settings for -max*gbttime are both 0 in this release, so it has no effect on node behavior when the default options are used.

-rejectsubversion configuration option

This can be used to reject peers which have certain fixed strings in their user agents. Useful for blocking non-compatible SV and ABC peers. The option can be specified multiple times to filter several matches.


bitcoind -rejectsubversion="Bitcoin SV" -rejectsubversion="Bitcoin ABC"

Care should be taken to filter out only peers which are definitely not useful to your Bitcoin Cash node.

Deprecated functionality

In the getmempoolentry RPC call, the verbose modes of the getrawmempool/getmempoolancestors/getmempooldescendants RPC calls, and the JSON mode of the mempool REST call, the height field is deprecated and will be removed in a subsequent release. This field indicates the block height upon mempool acceptance.

The bip125-replaceable field in the result of gettransaction is deprecated and will be removed in a subsequent release.

The arc lint linting is considered deprecated and developers should use the ninja check-lint target instead.

Modified functionality

Mempool expiry works slightly differently now. Previously, the expiry of an old mempool tx would be checked thoroughly every time a new tx was accepted to the mempool, but this consumed a bit of extra memory to accomplish precisely and efficiently. Instead, we save on memory by doing a fast (imprecise) check each time a new tx is added to the mempool. This check may miss some txs that should be expired. In order to catch those txs, we now also run a perfect (slower) expiry check of the mempool periodically. A new CLI arg, -mempoolexpirytaskperiod= was added to control the frequency of this thorough check (in hours). The new argument's default value is "24" (once per day).

Removed functionality

Manpages are no longer available in the autotools build system. You must switch to the CMake build system to continue using manpages. Note the autotools build system has been deprecated since v22.0.0.

New RPC methods


The 'validateblocktemplate' RPC call has been added. This call checks if a block template would be accepted if the hash solution were solved. The semantics of this call are the same as on BCHUnlimited from where a substantial portion of this new functionality has been ported. It is intended to be used by services that test compatibility of block generation with BCHN's consensus rules.

getdsproof and getdsprooflist

getdsproof retries more information about a specific double spend proof.

getdsprooflist lists the double spend proofs that are known about transactions in the node's mempool.

Please refer to the documentation pages for getdsproof and getdsprooflist for details about additional arguments and the returned data.

New ZeroMQ (ZMQ) notifications

BCHN can now publish notification of both hashes and full raw double spend proofs generated or accepted by the node.

The notifications can be enabled via the -zmqpubhashds=address and -zmqpubrawds=address configuration options where address must be a valid ZeroMQ endpoint. Please refer to the ZMQ API documentation for further details.

Low-level RPC changes

The getblockstats RPC is faster for fee calculation by using BlockUndo data. Also, -txindex is no longer required and getblockstats works for all non-pruned blocks.

In the getmempoolentry RPC call, the verbose modes of the getrawmempool/getmempoolancestors/getmempooldescendants RPC calls, and the JSON mode of the mempool REST call, the fields fee and modifiedfee are removed. These fields were deprecated since v0.20.4. Please use the fees subobject instead.

The (non-default) option in the getnetworkhashps RPC call to calculate average hashrate using "blocks since last difficulty change" has been removed. The option relied on an incorrect assumption of when the last difficulty change happened. On Bitcoin Cash, difficulty changes every block, rendering the option meaningless. The removal of this option was announced in the release notes of v22.2.0.

User interface changes

The transaction viewer (configurable via the Settings -> Display dialog) configuration now accept only valid HTTP or HTTPS URLs. Existing URLs that do not conform to these schemes are not displayed in the context menu.

Qt GUI settings are no longer automatically copied from Bitcoin ABC on first use of Bitcoin Cash Node.


Bitcoin Cash Node 23.0.0 does not introduce any known regressions compared to 22.2.0.

Known Issues

Some issues could not be closed in time for release, but we are tracking all of them on our GitLab repository.

  • MacOS versions earlier than 10.12 are no longer supported. Additionally, Bitcoin Cash Node does not yet change appearance when macOS "dark mode" is activated.

  • Windows users are recommended not to run multiple instances of bitcoin-qt or bitcoind on the same machine if the wallet feature is enabled. There is risk of data corruption if instances are configured to use the same wallet folder.

  • Some users have encountered unit tests failures when running in WSL environments (e.g. WSL/Ubuntu). At this time, WSL is not considered a supported environment for the software. This may change in future.

The functional failure on WSL is tracked in Issue #33. It arises when competing node program instances are not prevented from opening the same wallet folder. Running multiple program instances with the same configured walletdir could potentially lead to data corruption. The failure has not been observed on other operating systems so far.

  • doc/ needs revision (Issue #65).

  • test_bitcoin can collide with temporary files if used by more than one user on the same system simultaneously. (Issue #43)

  • For users running from sources built with BerkeleyDB releases newer than the 5.3 which is used in this release, please take into consideration the database format compatibility issues described in Issue #34. When building from source it is recommended to use BerkeleyDB 5.3 as this avoids wallet database incompatibility issues with the official release.

  • The test_bitcoin-qt test executable fails on Linux Mint 20 (see Issue #144). This does not otherwise appear to impact the functioning of the BCHN software on that platform.

  • An 'autotools' build (the old build method) fails on OSX when using Clang. (Issue #129)

  • With a certain combination of build flags that included disabling the QR code library, a build failure was observed where an erroneous linking against the QR code library (not present) was attempted (Issue #138).

  • The 'autotools' build is known to require some workarounds in order to use the 'fuzzing' build feature (Issue #127).

  • Some functional tests are known to fail spuriously with varying probability. (see e.g. issue #148, and a fuller listing in #162).

  • Possible out-of-memory error when starting bitcoind with high excessiveblocksize value (Issue #156)

  • There are obstacles building the current version on Ubuntu 16.04 (see #187). These are worked around by our packaging system, but users trying to build the software from scratch are advised to either upgrade to more recent Ubuntu, or retrofit the necessary toolchains and perform the same build steps for Xenial as registered in our packaging repository, or build in a VM using the gitian build instructions, or run our reproducible binary release builds. There is ongoing work on the build system to address underlying issues, but the related code changes were not ready in time for the v23.0.0 release.

  • A problem was observed on scalenet where nodes would sometimes hang for around 10 minutes, accepting RPC connections but not responding to them (see #210).

  • In the getmempoolentry RPC call, the verbose modes of the getrawmempool/getmempoolancestors/getmempooldescendants RPC calls, and the JSON mode of the mempool REST call, the height field shows an incorrect block height after a node restart. Note the field is deprecated and will be removed in a subsequent release.

  • On some platforms, the splash screen can be maximized, but it cannot be unmaximized again (see #255). This has only been observed on Mac OSX, not on Linux or Windows builds.
