Problems solved by technology

But even after 6 block heights, once a fork occurs on the main chain, the parachains of different nodes will still be synchronized to different block information, resulting in inconsistencies between the parachains of each node

Abstract

A parallel chain data synchronization method, device and storage medium. The method comprises: the first block operation sequence information is obtained, a block of the main chain is synchronized according to the first block operation sequence information to generate or update parallel chains, the first block operation sequence information further includes an operation sequence number and operation information of the block which are revoked by the node of the main chain when the revoking block is executed, the first block operation sequence information includes operation sequence numbers andoperation information of each block of the main chain. The first block operation sequence information includes operation sequence numbers and operation information of each block of the main chain. Thefirst block operation sequence information includes operation sequence numbers and operation information of each block. The invention realizes a parallel chain data synchronization method which can quickly synchronize the data of the main chain blocks and does not cause the inconsistency of the parallel chain data of each node due to bifurcation and other reasons.

Description

technical field [0001] The present application relates to the technical field of Internet finance, and specifically relates to a parallel chain data synchronization method, device and storage medium. Background technique [0002] In the existing parallel chain data synchronization mode, in order to avoid the problem of inconsistency in the synchronized block information of the parallel chains of each node due to reasons such as the fork of the main chain, the parallel chain adopts a zone whose synchronization lags behind the main chain by several block heights. block information method to synchronize the block information of the main chain; taking the block chain where a certain cryptocurrency is located as an example, it is generally believed that after a block is packaged and generated, after 6 block heights, it can be considered that the block has basically It is confirmed that if the block height of the block on the main chain of the node is H, then the parachain of the ...
