9/10

Cloudflare Research introduced Meerkat, a global consensus service that uses the QuePaxa asynchronous consensus algorithm, designed for geographically distributed systems. Meerkat represents a novel production attempt at asynchronous consensus, which can make progress even under extreme network latency variability, potentially enabling strongly consistent services across global networks. The algorithm is leaderless and does not rely on timeouts, but requires global consensus for every operation, including reads, which may increase latency. It is currently an experiment and not yet in production.
