Cloudflare has chosen to use QuePaxa, a leader-optional consensus algorithm, for its experimental global consensus service, Meerkat, which allows distributed systems to agree on an ordered log of events. Unlike traditional consensus algorithms such as Raft and Multi-Paxos, QuePaxa is designed to handle high and variable latency, making it suitable for global-scale deployments. By using QuePaxa, Meerkat can maintain progress even when the network is misbehaving, and Cloudflare's implementation has shown promising results, highlighting the limitations of traditional consensus algorithms in global-scale environments and the potential benefits of newer, more adaptive approaches like QuePaxa.
