Abstract

In order to solve the problem of delegated proof-of-stake(DPoS) consensus mechanism that inactive node voting and node corruption, this paper proposed a DPoS consensus mechanism based on matching mechanism. According to the node attribute value, the nodes were divided into autonomy nodes, master nodes and ligand nodes. Through the pairing of the master node and the ligand node, it increased the interaction force between nodes, and improved the enthusiasm of all kinds of nodes to participate in the consensus, thereby reducing the degree of system centralization. It used the category evaluation module to calculate the node's behavior weight value and updated the node category according to the node's behavior, so that the system's rewards and punishments for nodes were more targeted. When a new node joined the system, it used the Mahalanobis distance calculation formula to find the community that needed the node most to ensure the dynamic and balanced operation of the community. After 80 minutes of simulation, compared with DDPoS, DPoS-PI and DPoS algorithms, the nodes participation by DPoS-M2 increases by 21.9%, 8.7% and 32.4% respectively; the number of blocks generated increases by 63.2%, 44.8% and 11.6% respectively, the participation rate of new nodes increases by 22.8%, 25.5% and 28.7% respectively, and the elimination speed of malicious nodes increase by 12%, 32% and 48% respectively. The experiment results show that DPoS-M2 can effectively improve the enthusiasm of nodes and the degree of decentralization of the system, accelerate the speed of block generation, improve the expandability and enhance the security of the system.
