CometBFT Compatibility

cometbft-rs has been tested for compatibility with CometBFT v0.34.x, v0.37.x and v0.38.x.


Tested against the latest stable version of Rust. May work with older versions.

Semantic Versioning

We do our best to follow Semantic Versioning. However, as we are pre-v1.0.0, we use the MINOR version to refer to breaking changes and the PATCH version for features, improvements, and fixes.

We use the same version for all crates and release them collectively.


See each component for the relevant documentation.



Release tags can be found on GitHub.

Crates are released on crates.io.


The CometBFT protocols are specified in English in the cometbft/cometbft repo. Any protocol changes or clarifications should be contributed there.

This repo contains the TLA+ specifications and Rust implementations for various components of CometBFT. See the CONTRIBUTING.md to start contributing.
