Abstract

The invention discloses a blockchain node synchronization method and a device, and the method comprises the steps: determining a plurality of first target nodes from a blockchain network; determininga target contract account from the system table entry according to the target block height; for each first target node, determining a target contract account requested to the first target node, generating a synchronization request and sending the synchronization request to the first target node; and determining state data of the corresponding target contract account on the target block height andreturning the state data by the first target node. The method and the device are used for improving the block synchronization efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the field of financial technology (Fintech), and in particular to a method and device for synchronizing blockchain nodes. Background technique [0002] With the development of computer technology, more and more technologies (such as blockchain, cloud computing or big data) are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology, and blockchain technology is no exception, but Due to the security and real-time requirements of the financial and payment industries, higher requirements are also placed on blockchain technology. [0003] When a new node is added to the blockchain network, the newly added node needs to correctly synchronize the state data of the existing node before it can participate in the consensus as a consensus node. In the existing technology, the newly added node synchronizes the block from the existing node, and after ...
