Problems solved by technology

[0002] In the parachain mechanism proposed by the applicant (for details, please refer to the patent texts of various parachains applied by the applicant), the parachain node needs to obtain all the parachain transactions of this parachain by traversing each main chain block to generate Parallel chain blocks; in fact, not every main chain block has the parallel chain transactions of this parachain, the above mechanism will cause waste of bandwidth and time-consuming problems

Abstract

The invention provides a parallel chain block synchronization method and device and a storage medium. The method comprises the steps: sending first request information to a main chain node; segmentinga main chain height set into a plurality of subsets according to the block heights in an ascending order; sequentially and synchronously executing the steps A-C on each subset according to the blockheights in an ascending order: A, downloading a first data set of each first main chain block corresponding to each first main chain block height in the current subset to the main chain node; B, downloading all main chain block heads of a first block height section corresponding to the current subset to a main chain node; and C, after the step A and the step B of the previous subset are executed,verifying the block head and the parallel chain transaction Merkel root, and generating each parallel chain block corresponding to the previous subset if the verification is successful. According to the invention, the bandwidth of the parallel chain node synchronization parallel chain block is reduced, and the time consumption of the parallel chain node synchronization parallel chain block is reduced.

Description

technical field [0001] The present application relates to the technical field of block chains, in particular to a parallel chain block synchronization method, device and storage medium. Background technique [0002] In the parachain mechanism proposed by the applicant (for details, please refer to the patent texts of various parachains applied by the applicant), the parachain node needs to obtain all the parachain transactions of this parachain by traversing each main chain block to generate Parallel chain blocks; in fact, not every main chain block has the parallel chain transactions of this parachain, the above mechanism will cause problems of wasting bandwidth and time-consuming. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a parallel chain block synchronization that reduces the bandwidth of parallel chain nodes to synchronize parallel chain blocks, and reduces the time-consuming per...
