Abstract

Blockchain is a distributed system. In order to achieve the consistency of data and operation, consensus algorithm needs to be adopted. In the practical application, there are the log replication consensus algorithm raft and state machine replication consensus algorithm PBFT in the consortium blockchain. This paper makes a comparative study based on the principles and characteristics of the two algorithms, and makes a comparative study on the performance with experiments in FISCO BCOS. The results show that the PBFT consensus algorithm consumes more CPU resources than raft due to the complexity of its interaction, and the memory resources occupied by the network using raft consensus algorithm are more than those occupied by the network using PBFT consensus algorithm.
