Abstract

PBFT algorithm, which is widely used in consortium chain, has high network complexity, low consensus speed, and query speed. This paper proposed a consensus algorithm based on a time-weighted value(TWV). Firstly, aiming at the problems of high network complexity and slow consensus speed, TWV consensus algorithm selected the appropriate consensus node through the time weight value of the node to reduce the size of the consensus node. Combined with the view replacement protocol in PBFT algorithm, it replaced the consensus node at this time by a node with a higher time weight value. Secondly, it improved the efficiency of data query and synchronization by using the characteristics of low latency, long online time and data storage capacity of consensus nodes. Finally, through the local multi-node simulation experiments, it proves that TWV consensus algorithm improves the data query efficiency and throughput compared with PBFT consensus algorithm, and effectively reduces the time for nodes to reach consensus.
