    Release notes

    December 17, 2024

    This is a major release of CometBFT that includes several substantial changes that aim to reduce bandwidth consumption, enable modularity, improve integrators' experience and increase the velocity of the CometBFT development team, including:

    1. Proposer-Based Timestamps (PBTS) support. PBTS is a Byzantine fault-tolerant algorithm used by CometBFT for computing block times. When activated on a chain, it replaces the pre-existing BFT-time algorithm. See spec doc for PBTS.
    2. Validators now proactively communicate the block parts they already have so others do not resend them, reducing amplification in the network and reducing bandwidth consumption.
    3. An experimental feature in the mempool that allows limiting the number of peers to which transactions are forwarded, allowing operators to optimize gossip-related bandwidth consumption further.
    4. An opt-in nop mempool, which allows application developers to turn off all mempool-related functionality in Comet such that they can build their own transaction dissemination mechanism, for example a standalone mempool-like process that can be scaled independently of the consensus engine/application. This requires application developers to implement their own gossip/networking mechanisms. See ADR 111 for details.
    5. The first officially supported release of the data companion API.
    6. Versioning of both the Protobuf definitions and RPC. By versioning our APIs, we aim to provide a level of commitment to API stability while simultaneously affording ourselves the ability to roll out substantial changes in non-breaking releases of CometBFT. See ADR 103 and ADR 107.
    7. Moving many Go packages that are currently publicly accessible into the internal directory such that the team can roll out substantial changes in future without needing to worry about causing breakages in users' codebases. The massive surface area of previous versions has in the past significantly hampered the team's ability to roll out impactful new changes to users, as previously such changes required a new breaking release (which currently takes 6 to 12 months to reach production use for many users). See ADR 109 for more details.

    None of these changes are state machine-breaking for CometBFT-based networks, but could be breaking for some users who depend on the Protobuf definitions type URLs.

    See the upgrading guidelines and the specific changes below for more details. In this release, we are also introducing a migration guide, please refer to the Upgrading from CometBFT v0.38.x to v1.0 document.

    NB: This version is still a release candidate, which means that API-breaking changes, although very unlikely, might still be introduced before the final release. See RELEASES.md for more information on the stability guarantees we provide for pre-releases.

    IMPROVEMENTS

    • [abci/client] Add consensus-synchronized local client creator, which only imposes a mutex on the consensus "connection", leaving the concurrency of all other "connections" up to the application (#1141)
    • [abci/client] Add fully unsynchronized local client creator, which imposes no mutexes on the application, leaving all handling of concurrency up to the application (#1141)
    • [abci] Increase ABCI socket message size limit to 2GB (#1730: @troykessler)
    • [blockstore] Remove a redundant Header.ValidateBasic call in LoadBlockMeta, 75% reducing this time. (#2964)
    • [blockstore] Use LRU caches for LoadBlockPart. Make the LoadBlockPart and LoadBlockCommit APIs return mutative copies, that the caller is expected to not modify. This saves on memory copying. (#3342)
    • [blockstore] Use LRU caches in blockstore, significiantly improving consensus gossip routine performance (#3003)
    • [blocksync] Avoid double-calling types.BlockFromProto for performance reasons (#2016)
    • [blocksync] Request a block from peer B if we are approaching pool's height (less than 50 blocks) and the current peer A is slow in sending us the block (#2475)
    • [blocksync] Request the block N from peer B immediately after getting NoBlockResponse from peer A (#2475)
    • [blocksync] Sort peers by download rate (the fastest peer is picked first) (#2475)
    • [blocksync] make the max number of downloaded blocks dynamic. Previously it was a const 600. Now it's peersCount * maxPendingRequestsPerPeer (20) (#2467)
    • [cli/node] The genesis hash provided with the --genesis-hash is now forwarded to the node, instead of reading the file. (#1324)
    • [config] Added [storage.pruning] and [storage.pruning.data_companion] sections to facilitate background pruning and data companion (ADR 101) operations (#1096)
    • [config] Added genesis_hash storage parameter, which when set it is checked on node startup (#1324)
    • [config] Added recheck_timeout mempool parameter to set how much time to wait for recheck responses from the app (only applies to non-local ABCI clients). (#1827)
    • [config] Dynamic mempool type when writing config (#4281)
    • [config] Remove unused GenesisHash flag (#3595)
    • [config] Use embed pkg for the default template (#3057)
    • [consensus/state] Remove a redundant VerifyBlock call in FinalizeCommit (#2928)
    • [consensus] Add chain_size_bytes metric for measuring the size of the blockchain in bytes (#2093)

    • [consensus] Log vote validation failures at info level (#1022)
    • [consensus] Lower the consensus blocking overhead of broadcasts from num_peers * process_creation_time to process_creation_time. (#3180)
    • [consensus] Make Vote messages only take one peerstate mutex (#3156)
    • [consensus] Make broadcasting HasVote and HasProposalBlockPart control messages use TrySend instead of Send. This saves notable amounts of performance, while at the same time those messages are for preventing redundancy, not critical, and may be dropped without risks for the protocol. (#3151)
    • [consensus] Make the consensus reactor no longer have packets on receive take the consensus lock. Consensus will now update the reactor's view after every relevant change through the existing synchronous event bus subscription. (#3211)
    • [consensus] New metrics (counters) to track duplicate votes and block parts. (#896)
    • [consensus] Optimize vote and block part gossip with new message HasProposalBlockPartMessage, which is similar to HasVoteMessage; and random sleep in the loop broadcasting those messages. The sleep can be configured with new config peer_gossip_intraloop_sleep_duration, which is set to 0 by default as this is experimental. Our scale tests show substantial bandwidth improvement with a value of 50 ms. (#904)
    • [consensus] Reduce the default MaxBytes to 4MB and increase MaxGas to 10 million (#1518)
    • [consensus] Reuse an internal buffer for block building to reduce memory allocation overhead. (#3162)
    • [consensus] Use an independent rng for gossip threads, reducing mutex contention. (#3005)

    • [e2e] Allow disabling the PEX reactor on all nodes in the testnet (#1579)
    • [e2e] Allow latency emulation between nodes. (#1560)
    • [e2e] Introduce the possibility in the manifest for some nodes to run in a preconfigured clock skew. (#2453)

    • [grpc] Set grpc.MaxConcurrentStreams to 100 to limit the maximum number of concurrent streams per connection. (#1546)
    • [indexer] Optimized the PSQL indexer (#2142) thanks to external contributor @k0marov !
    • [internal/bits] 10x speedup and remove heap overhead of bitArray.PickRandom (used extensively in consensus gossip) (#2841).
    • [internal/bits] 10x speedup creating initialized bitArrays, which speedsup extendedCommit.BitArray(). This is used in consensus vote gossip. (#2959).
    • [jsonrpc] enable HTTP basic auth in websocket client (#2434)
    • [libs/json] Lower the memory overhead of JSON encoding by using JSON encoders internally. (#2846)
    • [libs/pubsub] Allow dash (-) in event tags (#3401)
    • [linting] Removed undesired linting from Makefile and added dependency check for codespell. (#1958)

    • [log] allow strip out all debug-level code from the binary at compile time using build flags (#2847)
    • [mempool] Add a metric (a counter) to measure whether a tx was received more than once. (#634)
    • [mempool] Add experimental feature to limit the number of persistent peers and non-persistent peers to which the node gossip transactions. (#1558) (#1584)
    • [config] Add mempool parameters experimental_max_gossip_connections_to_persistent_peers and experimental_max_gossip_connections_to_non_persistent_peers for limiting the number of peers to which the node gossip transactions. (#1558) (#1584)
    • [mempool] Before updating the mempool, consider it as full if rechecking is still in progress. This will stop accepting transactions in the mempool if the node can't keep up with re-CheckTx. (#3314)
    • [mempool] New Entry and Iterator interfaces. New CListIterator data struct to iterate on the mempool's CList instead of methods TxsFront and TxsWaitChan (#3303).
    • [metrics] Add evicted_txs metric to mempool (#4019)
    • [node] On upgrade, after #1296, delete the genesis file existing in the DB. (#1297)

    • [p2p/conn] Minor speedup (3%) to connection.WritePacketMsgTo, by removing MinInt calls. (#2952)
    • [p2p/conn] Remove the usage of a synchronous pool of buffers in secret connection, storing instead the buffer in the connection struct. This reduces the synchronization primitive usage, speeding up the code. (#3403)
    • [p2p/conn] Removes several heap allocations per packet send, stemming from how we double-wrap packets prior to proto marshalling them in the connection layer. This change reduces the memory overhead and speeds up the code. (#3423)
    • [p2p/conn] Speedup connection.WritePacketMsgTo, by reusing internal buffers rather than re-allocating. (#2986)

    • [p2p] make PeerSet.Remove more efficient (Author: @odeke-em) #2246
    • [privval] DO NOT require extension signature from privval if vote extensions are disabled. Remote signers can skip signing the extension if skip_extension_signing flag in SignVoteRequest is true. (#2496)
    • [proto] Add skip_extension_signing field to the SignVoteRequest message in cometbft.privval.v1 (#2522). The cometbft.privval.v1beta2 package is added to capture the protocol as it was released in CometBFT 0.38.x (#2529).
    • [protoio] Remove one allocation and new object call from ReadMsg, leading to a 4% p2p message reading performance gain. (#3018)
