BFT Consensus Mechanism

Definition

A BFT consensus mechanism enables distributed systems to agree on data even with faulty participants. Byzantine Fault Tolerance (BFT) protocols ensure all honest nodes reach agreement on the same value despite some nodes potentially behaving maliciously or failing. These mechanisms are crucial for maintaining data integrity and system reliability in environments where trust cannot be assumed across all participants. They achieve this by requiring a supermajority of honest nodes to validate and commit transactions.
