iq-cometbft-rs
iqlusion's fork of CometBFT client framework in Rust with TLA+ specifications.
CometBFT is a high-performance blockchain consensus engine for Byzantine fault tolerant applications written in any programming language.
CometBFT Compatibility
cometbft-rs has been tested for compatibility with CometBFT v0.34.x, v0.37.x and v0.38.x.
Requirements
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.
