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 of sending first request information to a main chain node to obtain first block header information of each main chain block height; sending second request information to the main chain node to obtain a first main chain block height of each first main chain block ofthe parallel chain transaction of the current parallel chain; sending third request information to the main chain node to obtain a first data set of the requested height of each first main chain block; performing the following operations on each received first data set: verifying whether the block header information is the same or not; if yes, generating a first parallel chain transaction Merkel root according to each first parallel chain transaction in the first data set; verifying whether the Merkel roots of the parallel chain transactions are the same or not; and if yes, generating a firstparallel chain block according to each first parallel chain transaction. 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 method, device, and storage medium. [0004] In the first aspect, the present invention provides a parallel chain block s...
