Byzantine Fault Tolerance (BFT)
Also known asBFT
The ability of a distributed system to reach consensus despite some nodes behaving arbitrarily (maliciously or failing). BFT algorithms tolerate up to f faulty nodes in a network of 3f+1 total nodes (1/3 threshold). Solana's Tower BFT, Tendermint, and PBFT are BFT consensus variants. BFT is essential for permissionless blockchains.
