摘要
共识机制是区块链技术应用的核心,本文分析了现有多种典型共识机制的技术原理、技术特点、应用场景、选择标准,为区块链研究者、开发者选择共识机制提供参考和建议。文中介绍了各种主流共识机制的基本原理,并分别分析了各种共识机制的优缺点,随后从性能效率、去中心化程度、是否需要代币等几个方面对各种共识机制特点作了比较,分析了现实生活中常见的两种区块链应用场景,并提出了五个维度的共识机制选择标准。
The consensus mechanism is the core of the application of blockchain technology.This paper analyzes various typical technical principles,technical features,application scenarios and selection criteria of the consensus mechanism,and provides reference and suggestions for the blockchain researchers and developers on selecting consensus mechanism.This paper firstly introduces the basic principles of various popular consensus mechanisms and compares the advantages and disadvantages of various consensus mechanisms.Subsequently,the characteristics of various consensus mechanisms are compared from the aspects of performance efficiency,degree of de centralization,and need for tokens.And then,this paper analyzes two common application scenarios of blockchain in real life,and finally puts forward a five-dimensional selection criterion of consensus mechanism.
