Abstract: A method for active failure recovery of a single node improved based on PBFT algorithm is disclosed. The abnormal node first initiates a view change request, if (2f+1) view change requests containing the same view value cannot be received within a specified period of time, the abnormal node enters a state to be recovered, and the node to be recovered initiates a recovery request to all nodes of the whole network, waits for replies from normal nodes and counts the number of replies, calculates a height of stable checkpoint of the whole network after receiving replies contain the same view value from (2f+1) nodes, and update the state thereof to finally complete the recovery. This method solves an inherent problem in the PBFT algorithm that a failure in a single node cannot be recovered autonomously, so that a practicability of the PBFT algorithm is greatly improved.
