Title:
BLOCKCHAIN NODE SYNCHRONIZATION METHOD AND DEVICE USING TRUST MECHANISM
Document Type and Number:
WIPO Patent Application WO/2020/000708
Kind Code:
A1
Abstract:
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. The present invention can ensure that the selected target node for synchronization has a large TD value, and also has a good network status, and the probability of an error occurring at the node is low, thereby ensuring the stability of synchronization operations from various aspects and improving the success rate of synchronization.
