This article demystifies the Paxos consensus algorithm by explaining it in plain English, arguing that its core single-decree version is intuitive and simple despite common perceptions of complexity. It outlines the consensus problem's key properties—agreement, integrity, validity, and termination—and connects Paxos to practical distributed systems applications like leader election and replicated databases.
Background
Paxos is a foundational consensus algorithm in distributed systems, often criticized for its perceived complexity, but essential for ensuring agreement among multiple processes in unreliable networks.
