摘要
随着区块链技术的快速发展,越来越多的机构尝试将区块链融入到自己的应用中,区块链也被分成更细的三种:公有链、联盟链、私有链。联盟链和私有链因无需过多的无意义算力浪费而受到更多开发者的选择。Raft共识算法作为当前主流的一致性算法,可以作为分布式架构和私有链的核心算法。对于Raft算法中无法解决恶意节点攻击的问题进行改进,改进后的算法既保留Raft算法强一致性的高效性能,也可以防止恶意节点的攻击,为以后研究者们对私有链搭建提供更多的选择。
With the rapid development of blockchain technology,more and more organizations are trying to integrate blockchain into their own applications,and blockchain are also divided into three more:public chain,alliance chain,and private chain.The alliance chain and the private chain are chosen by more developers because they do not require too much meaningless power to waste.As the current mainstream consistency algorithm,Raft consensus algorithm can be used as the core algorithm of distributed architecture and private chain.The Raft algorithm cannot solve the problem of malicious node attack.The improved algorithm not only retains the high-efficiency performance of the Raft algorithm,but also prevents the attacks of malicious nodes,which provides the private chain construction for future researchers more choices.
