【Abstract】Consensus algorithm, which allows distrust nodes to reach a consensus in the overall state of the block -chain, is one of the basic characteristics of the blockchain network. Since the delegate nodes elected in the DPoS consensus algorithm are always nodes with a large amount of currency, it usually leads to low vot-ing activity of other nodes. To solve this problem, we propose a credit-weighted comprehensive election, codenamed as CW-DPoS. We propose that the voting weight of nodes is positively correlated with the credit value. First calculate the activity of the node based on k-shell,second calculate the weighted voting value of the node. Finally, the delegator is selected through the comprehensive method of node activity and weighted votes. The performance of the proposed method is compared with the existing consensus mechanism of DPoS, and the experimental result shows that the activity of the nodes has been improved to about 84% and selects honest nodes more fairly.(c) 2022 THE AUTHORS.
