{"id":"consensus-architectures-are-inverse-optimizations","text":"Raft and Total Order Broadcast represent contrasting approaches to Paxos optimization: Raft centralizes proposal authority in a single elected leader (one election per term, then Phase-2-only replication), eliminating dueling proposals within a term, while TOB allows any node to propose for any slot using full two-phase Paxos each time, making it susceptible to competing proposals.
