RW-PBFT consensus algorithm based on reward and punishment strategy

The invention discloses an RW-PBFT consensus algorithm based on a reward and punishment strategy. The method comprises the steps that all nodes are subjected to vocal degree calculation, nodes in the consensus process are divided into alternative primary nodes, secondary nodes and candidate secondary nodes according to vocal degree ranking, and the alternative primary nodes and the secondary nodes are used for participating in the consensus communication process and broadcasting messages; the candidate secondary nodes are used for receiving broadcast information and storing logs and related records, but do not participate in a consensus communication process; the reward degree comprises a reward degree reward and a reward degree punishment degree; and selecting a master node from the alternative master nodes, and entering the RW-PBFT consensus flow of the next round of preparation stage, preparation stage and submission stage. According to the method, the nodes participating in the consensus are classified, a
