In this paper,a DL-DPoS consensus mechanism is proposed in view of the low voting enthusiasm ofnodes in the DPoS consensus mechanism and the malicious nodes endangering the security and stability of the system.First,by introducing the Link mechanism,the characteristics of active nodes are fully exploited,active nodes drive inactive nodes to enhance the enthusiasm of nodes to participate in voting.Its comprehensive credit value is calculated,and finally the block reward is dynamically adjusted to make the system more stable.The experimental verification shows that the throughput of the DL-DPoS consensus mechanism is in-creased by 23.1%compared with the DPoS consensus mechanism,the node participation is increased by 40%,and the distribution of rights and interests is more reasonable,which proves that the DL-DPoS consensus mechanism has better performance,security and stability.
