What is CometBFT?

CometBFT comprises two primary technical components:

  • a blockchain consensus engine

  • and a generic application interface.

The consensus engine ensures the orderliness and sameness of transactions on every machine.

The generic application interface (Application Blockchain Interface (ABCI)) enables the transactions to be processed in any possible programming language.

CometBFT is a general-purpose blockchain consensus engine capable of hosting arbitrary application states. CometBFT, due to its arbitrary application-replicating ability, can be used as a plug-and-play replacement for other blockchain consensus engines. CometBFT also offers a better blockchain design and API than many consensus engines.

Vince Chain and Cosmos Network are typical ABCI applications replacing Ethereum's Proof of Work consensus mechanism through CometBFT's consensus engine.
