Abstract With the rapid development of blockchain technology, more and more
people are paying attention to the consensus mechanism of blockchain. Practical
Byzantine Fault Tolerance (PBFT), as the first efficient consensus algorithm
solving the Byzantine Generals Problem, plays an important role. But PBFT also
has its problems. First, it runs in a completely closed environment, and any node
can't join or exit without rebooting the system. Second, the communication
complexity in the network is as high as O(n2), which makes the algorithm only
applicable to small-scale networks. For these problems, this paper proposes an
Optimized consensus algorithm, Excellent Practical Byzantine Fault… More >
