Abstract

Considering the characteristics and requirements of blockchain used in the Internet of Things environment, this paper analyzed the various shortcomings of the PBFT algorithm which was currently used in alliance chains widely and the general problems existing in threshold signature algorithm applied in consensus networks. It also proposed an improved consensus algorithm. Firstly, the new consensus mechanism grouped the nodes in the network, and replaced the pairwise communication of all nodes with the pairwise communication of partial nodes to reduce the communications volume. Secondly, it introduced the idea of combining public keys into the threshold signature, which reduced the communications volume and calculation greatly. Finally, it used a credit point mechanism between nodes to optimize the view switching protocol. The simulation results show that the data throughput and communication delay of the newly proposed algorithm have been significantly improved. At the same time, this paper obtains the best grouping method when the communication volume is the lowest.
