Aiming at the problems of PBFT algorithm of consortium blockchain, such as high communication overhead, low consensus efficiency, and random selection of leader nodes, an optimized algorithm of PBFT is proposed. Firstly, the algorithm improves C4.5 and introduces weighted average information gain to overcome the mutual influence between conditional attributes and improve the classification accuracy. Then classify the nodes with improved C4.5, and select the ones with a high trust level to formdoi:10.1155/2021/5542078 doaj:0c2f2b88b1e64e5e99e1ab02f54e62b4 fatcat:4jrtgzdzubfbhcad4dr4v4xaca
