This Paxos demo is intended for learning purposes. This Paxos cluster has 5 nodes, which only has the capability to write one value once, and all subsequent queries must be reads. Figuring out how to extend the algorithm to support storing multiple key-value pairs, override an existing value, and other features are left as an exercise to the reader (because I can't be bothered to implement more features).
The implementation is based on the algorithm described in the Paxos Made Simple paper.
