BFT Consensus

Definition

BFT Consensus refers to a class of algorithms allowing distributed systems to reach agreement despite the presence of malicious or faulty nodes. This consensus mechanism ensures system integrity and consistency by tolerating arbitrary failures, including nodes sending contradictory messages to different participants. It is a critical component for achieving reliability in decentralized networks where trust among all participants cannot be presumed. BFT protocols aim for a deterministic finality, where transactions are confirmed without risk of reversal once agreed upon.
