区块链技术的集成应用在新的技术革新和产业变革中发挥着重要作用，全球多个国家都在加快布局区块链技术发展。我国已将区块链技术纳入“新基建”范围和“十四五”规划，全国多地出台了相关政策，积极鼓励区块链技术发展。而共识算法作为区块链技术的核心，从根本上决定了区块链整体性能和系统安全。本报告对区块链发展过程中的重要共识算法进行了回顾梳理，希望能为将来共识算法的创新和区块链技术的发展提供参考。
The integrated application of blockchain technology is a key driving force of new technological innovation and industrial transformation. Many countries around the world are accelerating the development of blockchain technology. China has incorporated blockchain technology into the “New Infrastructure” and the Fourteenth Plan，and many policies have been issued throughout the country to actively encourage technological development of block chains. Consensus algorithms，as the core of blockchain technology，fundamentally determine the system’s overall performance and system security. In this paper，we review and discuss the important consensus algorithms in blockchain development，providing references for the innovation and development of block link technology in the future.
