BFT State Machine Replication

Definition

BFT State Machine Replication is a method for building highly fault-tolerant distributed systems. This approach ensures that all honest nodes in a network maintain identical state despite the presence of Byzantine faults or malicious actors. It relies on a consensus algorithm where a supermajority of nodes must agree on the order and execution of operations. This mechanism provides strong consistency and availability, making systems resilient to failures and attacks.
