Paxos is a family of protocols for solving consensus in a network of unreliable processors. Consensus is the process of agreeing on one result among a group of participants. This problem becomes difficult when the participants or their communication medium may experience failures.

Consensus protocols are the basis for the state machine approach to distributed computing, as suggested by Leslie Lamport and surveyed by Fred Schneider.
