Byzantine fault-tolerant consensus
WebA. Consensus Most enterprise blockchain platforms use quorum-based consensus protocols to order transactions. Loosely speaking, crash fault tolerant (CFT) protocols like Raft [3] need a simple majority Q = 1 2 N, whereas “mainstream” Byzantine fault tolerant (BFT) protocols like PBFT [8] require a Q = 2 3 N majority (N size of cluster, Q ...
