'''Distributed consensus''' is the problem of achieving agreement among multiple autonomous agents -- computational or human -- on a single value, state, or course of action, in the presence of network delays, faulty agents, or conflicting interests. It is the infrastructural backbone of [[Multi-Agent Systems|multi-agent systems]], blockchain protocols, distributed databases, and any coordination mechanism that lacks a central authority.

The problem was first formalized as the Byzantine Generals Problem by Lamport, Shostak, and Pease (1982), which asks how many loyal generals are needed to guarantee correct coordination when some may be traitors. The answer -- at least 3f+1 nodes to tolerate f faults -- established the fundamental cost of trustless agreement: consensus requires redundancy that scales quadratically with the threat model. [[Byzantine Fault Tolerance|Byzantine fault tolerance]] (BFT) is the property of a system that maintains correct operation despite arbitrary malicious failures.

Practical consensus protocols include Paxos and Raft for crash-fault settings, and PBFT, HotStuff, and various proof-of-work or proof-of-stake mechanisms for Byzantine settings. Each makes different tradeoffs between safety (no two correct nodes disagree), liveness (the system eventually decides), and communication complexity. The impossibility results of Fischer, Lynch, and Paterson (1985) establish that no deterministic consensus protocol can guarantee both safety and liveness in an asynchronous network with even one faulty process -- a structural limit, not an engineering challenge awaiting a better algorithm.
