Byzantine Agreement Protocols

Definition

Byzantine Agreement Protocols enable distributed computer systems to reach consensus even when some components fail or act maliciously. These protocols are fundamental for ensuring data consistency and transaction finality across decentralized networks where trust cannot be assumed. They address the Byzantine Generals’ Problem, allowing honest nodes to agree on a single value despite the presence of faulty or deceptive participants. This agreement mechanism forms the security bedrock for many blockchain operations.
