Probabilistic atomic broadcast

摘要

Reliable distributed protocols, such as consensus and atomic broadcast, are known to scale poorly with large number of processes. Recent research has shown that algorithms providing probabilistic guarantees are a promising alternative for such environments. In this paper, we propose a specification of atomic broadcast with probabilistic liveness and safety guarantees. We present an algorithm that implements this specification in a truly asynchronous system (i.e., without assumptions about process speeds and message transmission times).
