The Performance Bottlenecks in Epaxos and Caesar

In Epaxos, each node can be a coordinator for the command it receives from clients. In Caesar, replicas communicate with each other and sort of build a graph that would tell them what the dependencies between these commands are. And based on thisdependencies, they can execute these commands in a deterministic way across all these different replicas. Thereby, you still get the highest possible consistency of linearizability.
