基于CAP理论的区块链共识机制的分析

Analysis of Blockchain Consensus Mechanism Based on CAP Theory

区块链作为一种全新的分布式存储机制,具有非常广泛的应用场景。共识机制作为区块链的核心技术之一,其性能对区块链的性能有一定的影响。为了更深入地了解共识机制,论文以CAP理论为依据,对现有的主流共识机制的共识过程进行了研究,并分析了对一致性和可用性的权衡,为区块链更广阔的应用开发提供了理论依据。

As a new distributed storage mechanism,the blockchain has a very wide application scene.As one of the core tech⁃nologies of blockchain,the performance of consensus mechanism has a certain influence on the performance of blockchain.In order to further understand the consensus mechanism,based on the CAP theory,this paper studies the consensus process of the existing mainstream consensus mechanism,and analyses the trade-off between consistency and availability,which provides a theoretical ba⁃sis for the wider application and development of blockchain.
