An urgent demand of deploying BFT consensus (e.g., atomic broadcast) over the Internet is raised for implementing (permissioned) blockchain services. The deterministic synchronous protocols can be simple and fast in good network conditions, but are subject to denial-of-service (or even safety vulnerability) when synchrony assumption fails. Asynchronous protocols, on the contrary, are robust against the adversarial network, but are substantially more complicated and slower for the inherent use of randomness.
