Practical Byzantine fault-tolerant consensus method and device and readable storage medium

The invention discloses a practical Byzantine fault-tolerant consensus method and device and a readable storage medium. The method comprises the following steps: constructing a tree topology network;wherein the tree topology network comprises a root node, an active sub-tree and a passive sub-tree; and completing the practical Byzantine fault tolerance consensus according to the tree topology network. According to the scheme, the traditional PBFT algorithm can be effectively expanded. 一种实用拜占庭容错共识方法及装置、可读存储介质，所述方法包括：构建树形拓扑网络；所述树形拓扑网络包括根节点、主动子树以及被动子树；根据所述树形拓扑网络，完成所述实用拜占庭容错共识。上述方案能够对传统PBFT算法进行有效扩展。
