摘　　要：针对委托权益共识机制(Delegated-Proof-of-Stake, DPOS)中存在的记账权集中在权重节点、节点投票不积极与恶意节点处理困难的问题,提出一种基于沙普利值的DPOS改进方案,对记账节点的选举进行优化适配,区块收益再分配以激励节点积极参与,并引入惩处机制快速剔除恶意节点。实验结果表明,改进后的DPOS机制能够提高节点的投票率,保证系统去中心化,降低恶意节点出块概率,提高整体稳定性与安全性。In view of the problems existing in Delegated-Proof-of-Stake(DPOS)mechanism,such as the fact that the bookkeeping right is concentrated in the weight nodes,the node voting is not active and the malicious nodes are difficult to handle,this paper proposes an improved DPOS mechanism based on Shapley value.The improved mechanism optimized the election of bookkeeping nodes,redistributed the block income to encourage the nodes to participate actively,and introduced a punishment mechanism to eliminate malicious nodes quickly.Experimental results show that the improved DPOS mechanism can improve the voting rate of nodes,ensure the decentralization of the system,reduce the probability of malicious nodes blocking,and improve the overall stability and security.
