Blockchain node synchronization method and device using trust mechanism

摘要

The present application proposes a blockchain node synchronization method and device using a trust mechanism. The method comprises: acquiring data throughput history data of each node in a routing table of a node to be synchronized; acquiring synchronization success rate history data of each node in the routing table of the node to be synchronized; acquiring a total difficulty value of a blockchain currently stored by each node in the routing table of the node to be synchronized; determining a credibility of each node in the routing table according to the data throughput history data, the synchronization success rate history data, and the total difficulty value of the blockchain; and selecting, according to the credibility of each node, a target node for synchronization, and synchronizing, according to blockchain data stored by the target node, the node to be synchronized.
