Paxos algorithm has been dubbed one of the most difficult algorithms to understand in distributed systems, yet it represents the first breakthrough in solving the problem of distributed consensus. That is, how can a set of servers in an unreliable environment like the Internet agree on the same valid value? Answering this question is key for designating a leader for a distributed task, committing changes to a replicated database and is a basis of many distributed lock systems like the Google Chubby. In this talk I will start from intuitive principles and examples and derive the complete algorithm.
