Consensus

Tendermint / CometBFT

Tendermint (now CometBFT) is a Byzantine fault-tolerant consensus engine that powers Cosmos SDK chains. CometBFT decouples consensus from application logic via the Application Blockchain Interface (ABCI), allowing custom blockchain applications in Go, Rust, and other languages.
