Abstract
This paper analyzes the advantages and disadvantages of the PBFT consensus algorithm and proposes an improved credit-based PBFT consensus algorithm(CPBFT). CPBFT changes the original C/S architecture to P2P architecture, reduces the consensus steps, and uses the voting method to elect the master node. In the election process, credit levels and credit coefficient are introduced, so that the probability that each node is elected as the master node is affected by the past behavior, and a reliable master node is elected more probably. Experiments show that compared with the PBFT algorithm, the CPBFT algorithm reduces the amount of data transmission on the network and increases the throughput.
