1. IntroductionIn order to maintain the block consistency of nodes, the consensus mechanism is essential in blockchain technology [1]. The Practical Byzantine Fault Tolerant (PBFT) consensus algorithm [2,3,4], which is an alternative to traditional resource proof-based consensus algorithms [5,6,7], addresses the issues of low throughput and resource wastage. Nevertheless, PBFT still faces challenges of inadequate scalability, low fault tolerance, and high communication latency.
