摘　　要：区块链作为一种新兴技术,其以完全去中心化的特点为分布式系统提供了一种新的计算范式。同时,区块链共识机制解决了分布式系统中节点之间互相信任的问题。文章介绍了区块链技术中常见的几类共识机制,并从安全性、可扩展性等多个维度对现有的共识机制进行了对比分析,梳理了共识机制所存在的问题,建立了共识机制的评价标准,从而明确了未来区块链共识机制的设计方向和具体思路。As an emerging technology,blockchain provides a new computing paradigm for distributed systems with its completely decentralized characteristics.At the same time,the blockchain consensus mechanism solves the problem of mutual trust between nodes in a distributed system.The article introduces several common consensus mechanisms in blockchain technology,and compares and analyzes the existing consensus mechanisms from multiple dimensions such as security and scalability,sorts out the problems existing in the consensus mechanism,and establishes a evaluation criteria of the consensus mechanism,thus clarifying the design direction and specific ideas of the future blockchain consensus mechanism.
