A vaPBFT block chain consensus method with high network performance and security is characterized in that nodes finally participating in consensus are screened out on the premise that randomness, fairness and effectiveness are guaranteed through an algorithm without communication between nodes. The final consensus node network scale is reduced: a, firstly, node types are divided into a final consensus node, a candidate consensus node and a common service node, and the final consensus node and the candidate consensus node are subjected to distributed consensus according to algorithm scheduling from the aspect of mechanism; the common service node does not participate in the consensus and only provides the block chain service; b, the final consensus node and the candidate consensus node can be mutually converted, and the conversion time is after each node block; the conversion basis is the consumption and accumulation condition of the node vitality value. 一种高网络性能与安全性的vaPBFT区块链共识方法，其特征在于，通过无需节点间进行通信的算法，在保证随机性、公平
