Byzantine paxos

Webpresent Fast Byzantine (or FaB) Paxos, the first Byzantine Paxos protocol, as far as we know, that requires only two communication steps to reach consensus in the common case. Confirming a conjecture by Lamport [12], we find that the reduced latency comes at a price: FaB Paxos requires 5f + 1 acceptors to toler-ate f Byzantine acceptors ... WebApr 5, 2024 · Weighted Byzantine Paxos. The final detail to add is adding weights to the agents. We’ll need to assign normalized weights to each server that acceptors and proposers will utilize to accept requests or move onto the next phases. Very similarly to the Byzantine Paxos algorithm, it turns out that agreement is impossible if more a weight of …
