Block chain consensus method based on credibility and banzhaf index

The invention relates to a block chain consensus method based on credibility and a banzhaf index, and belongs to the technical field of block chain consensus. According to the method, after system parameters are initialized, nodes generate random numbers through timestamps and private keys, and grouping and election are completed. The common nodes are responsible for packing transaction blocks and compete for the block right by solving the Hash problem, and the difficulty is adjusted according to the creditworthiness; and the super nodes randomly select blocks. And the verifier node checks the legality of the common block and votes, and if the number of votes exceeds half and the votes are supported by the high-credibility node, verification is passed and uplink is carried out. And after consensus is finished, updating creditworthiness according to node expression, and starting a next round of consensus. According to the method, the message processing speed of the node equipment in the block chain network dur
