Consensus
Noun · Development
Definitions
A process by which nodes in a distributed system agree on a single data value or state, even in the presence of failures. Algorithms like Paxos, Raft, and PBFT solve the consensus problem. Blockchain consensus mechanisms (PoW, PoS) are a specialized variant.
In plain English: How multiple computers that work together agree on the same answer, even when some of them might be broken or lying.
