Abstract

To reduce the communication complexity of the PBFT consensus algorithm and improve transaction throughput, this paper proposed MPBFT. The MPBFT consensus algorithm modified the information transmission method during the prepare and commit phases of the PBFT. The primary node used the MuSig multi-signature algorithm to aggregate the messages received from backup nodes into a single message and then broadcasted it to the backup nodes to verify the validity of the aggregated signature. Through performance analysis and experimental verification, the MPBFT consensus algorithm reduces the communication complexity of PBFT from O(n2) to O(n), demonstrating superior time performance and security. It outperforms the other three comparative algorithms in transaction latency, throughput, and communication overhead.
