This invention discloses an asynchronous network consensus method and system based on a reputation model, belonging to the field of consensus algorithm technology. It aims to solve the problems of low efficiency, high latency, and frequent leader election failures in asynchronous network environments. The method is divided into a broadcast phase and a consensus phase: In the broadcast phase, broadcast nodes encode erasure codes into message fragments and distribute them; receiving nodes verify these fragments and store them in the corresponding priority queues.

An asynchronous binary consensus protocol is used to reach a consensus on the leader's validity, determining a multi-value Byzantine consensus result. Finally, the original message is requested and restored from the node indicated by the result. Erasure coding reduces communication overhead, and the reputation model reduces the number of consensus failures, improving system throughput, reducing latency, and enhancing stability and efficiency in asynchronous network environments.
