BLOCKCHAIN DATA SYNCHRONIZATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

摘要

The present application is applied to the technical field of blockchains. Disclosed are a blockchain data synchronization method and apparatus, and an electronic device and a storage medium. The method comprises: acquiring, from a first connection node device, a total data tree corresponding to blockchain data, and on the basis of the value of a target total tree leaf node in the total data tree, acquiring, from a second connection node device, a target interval data tree corresponding to the target total tree leaf node; on the basis of the values of different target interval tree leaf nodes in the target interval data tree, acquiring, in parallel, at least one piece of target fragment data from each connection node device corresponding to a newly added node device; integrating the target fragment data into interval data of a target block interval corresponding to the target interval data tree; and then acquiring interval data of each block interval, and integrating the interval data of each block interval to obtain blockchain data, thereby completing the synchronization of the blockchain data. The method facilitates increasing the speed of synchronization of blockchain data.
