crash-fault-tolerant (CFT)

RU: crash-fault-tolerant (CFT)

A property of a distributed system that lets it continue operating correctly when some nodes crash and stop responding, but assumes all running nodes follow the protocol honestly. Raft and Paxos are CFT algorithms; they tolerate up to f failures with 2f+1 nodes. CFT is weaker than Byzantine fault tolerance, which also handles malicious or corrupted nodes.
