Paxos is a foundational consensus protocol introduced by Leslie Lamport, designed to help distributed systems reliably agree on decisions even when components fail or communication is unreliable.

In this video, we explain Paxos using the intuition behind Lamport’s famous fictional story of an ancient parliament—where part-time legislators, unreliable messengers, and frequent absences mirror real-world distributed system failures. From this narrative, we derive the core principles of Paxos based on quorums, voting, and immutability of decisions.

You’ll learn how Paxos guarantees safety by ensuring that once a value is chosen by a majority, it can never be overwritten. We also explore practical extensions of the protocol, including leader election, state-machine replication, and membership changes, which make Paxos usable in real production systems.

This video is essential for backend engineers, distributed systems learners, and system design interview preparation, especially for understanding how modern fault-tolerant infrastructure remains reliable in asynchronous environments.
