Research and Improvement of Blockchain DPoS Consensus Mechanism

Abstract

Aiming at the two major problems existing in the delegated proof of stake (Delegated Proof of Stake, DPoS) consensus mechanism, namely, the low enthusiasm of nodes to participate in voting and the inability of malicious nodes to deal with them quickly, the corresponding optimization scheme is proposed. First, establish a voting incentive mechanism to encourage token holders to participate in the consensus mechanism to vote and improve efficiency. Secondly, select representative nodes from the campaign nodes to perform bookkeeping and chaining in turn. These nodes supervise and inspect each other, which can detect and deal with malicious nodes in time, and ensure the security of consensus nodes. The experimental results show that the improved DPoS consensus mechanism improves the processing speed of malicious nodes, with faster operation efficiency and higher stability, and has certain application value.
