if you think of paxos/raft as having fault tolerance of losing n nodes, then the "decide what happens" part of 2 phase commit can be thought of as distributed consensus with a fault tolerance of 0 nodes. iirc leslie lamport has a paper that goes over this, and demonstrates that at n = 0 parts of paxos are vestigial and removing them directly maps to 2pc. EDIT: found it! https://lamport.azurewebsites.net/video/consensus-on-transaction-commit.pdf https://lamport.azurewebsites.net/video/consensus-on-transac... i am being a bit hand-wavey here because what the paper is talking about is an application of paxos to generate a new algorithm (paxos commit) that devolves to 2pc.
