主流区块链共识算法对比研究

共识算法是区块链中的核心技术,直接决定了整个区块链系统的运行效率。对现有的共识算法进行了总结,将其分为基于节点某种属性值证明的共识算法、基于节点投票机制的共识算法和类Paxos共识算法三类。详细介绍了三类共识算法的实现细节,并依据蒙代尔不可能三角理论进行对比研究,给出了共识算法的发展方向,为区块链共识算法的深入研究提供借鉴。

Comparative research on mainstream blockchain consensus algorithms

The consensus algorithm is the core technology in the blockchain, which directly determines the operating efficiency of the entire blockchain system. The paper summarized the existing consensus algorithms and divided them into three categories: consensus algorithm based on the proof of a certain attribute value of the node, consensus algorithm based on the node voting mechanism and Paxos-like consensus algorithm. Then it detailedly introduced the implementation details of the three categories of consensus algorithms, and comparatively studied based on Mundell''s impossible triangle theory, and given the development direction of the consensus algorithm, which provides reference for researchers to conduct in-depth research on the blockchain consensus algorithm.
