Research on the Performance Analysis of Mainstream Consensus Algorithms of Consortium Blockchains

The diverse range of consensus algorithms poses a challenge in selecting the most suitable one for practical application scenarios. Addressing the lack of quantitative performance comparison among consortium blockchain consensus algorithms, this paper quantifies key performance indicators in consensus algorithm evaluation. Furthermore, it designs a performance evaluation framework and employs it to conduct theoretical and empirical analyses of mainstream consensus algorithms in consortium blockchains. Finally, the paper outlines the advantages and limitations of each consensus algorithm and identifies the factors constraining their performance.
