The Paxos algorithm is a powerful building block for building highly available distributed systems. Paxos can be seen as a function paxos(k,v) that returns the same value on all servers in a group for a certain key (k), and the value is one of the inputs (v). Paxos is most commonly used to implement log replication through a technique called Multi-Paxos. In Multi-Paxos, nodes call paxos using the
