Abstract: Consensus algorithm is a key component of the blockchain technology, and also a hot topic in distributed systems research. In this paper, we systematically review and discuss 32 mainstream consensus algorithms emerged in the development process of blockchain. We introduce the classic distributed consistency algorithms, as well as the milestone research efforts and the key conclusions of distributed consensus algorithms. We also propose a novel model and classification approach of blockchain consensus algorithms. In the end, we summarize the consensus algorithms and their performance measures using an evolutionary tree. This is our preliminary research effort towards the blockchain consensus algorithm, aiming at offering useful guidance and reference for future innovation of novel consensus algorithms and the development of blockchain technology.
