Improvement and Research of Delegated Proof of Stake Consensus Mechanism.

In order to solve the problems of Delegated Proof of Stake (DPoS) consensus mechanism, such as low node activity, untimely elimination of error nodes, and unreasonable distribution of book keeping income, an improvement scheme is proposed. The improvement scheme mainly improves the counting mechanism and incentive mechanism of DPoS. The improved vote counting mechanism takes more information of the node as an integral part of the vote, so that the vote can more comprehensively reflect the credit status of the node. According to the voting record of the node, the weight of the node's vote is dynamically adjusted to speed up the elimination of the wrong node. The improvement of the incentive mechanism is divided into two parts: voting incentives and accounting incentives. The voting incentives provide corresponding incentives for all nodes participating in the consensus, and encourage the nodes in the system to actively participate in voting. Accounting incentive is based on the Banzhaf power index in game theory to carry out the secondary distribution of income, which makes the distribution mechanism more reasonable and helps to reduce the centralization trend of the system. The effectiveness of the improved scheme are verified by experiments. [ABSTRACT FROM AUTHOR]
