摘要： 针对联盟链的实用拜占庭容错(PBFT)共识算法在共识过程中节点间的隐私保护弱、网络结构静态、选取主节点不可靠和通信开销大的问题,提出一种基于可跟踪环签名的拜占庭容错共识算法(tracePBFT)。首先,随机将节点分为主域节点和副域节点并且赋予其不同的权量,选择权重高的主域节点为主节点;然后在准备阶段引入可追踪环签名对节点进行隐私保护,并且节点可以通过权重选择可靠节点,在确认阶段验证签名和跟踪拜占庭节点;最后适当惩罚拜占庭节点。这样选择的主节点更加可靠,减少因主节点出错而更换视图导致的通信开销。实验结果表明,相比传统的PBFT算法,tracePBFT算法在通信复杂度、安全性、吞吐量等方面均有一定的提高。
