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 generation method and device and a storage medium. The method comprises the following steps: after the consensus of the first main chain block succeeds, updating the temporary parallel chain queues corresponding to the first parallel chain nodes according to the first main chain block and storing the temporary parallel chain queues into a local database, so as to enable the first parallel chain nodes to synchronize the temporary parallel chain blocks of the corresponding temporary parallel chain queues from the local database to generate parallel chain blocks and execute the parallel chain blocks, wherein a temporary parallel chain block in the temporary parallel chain queue is generated by screening a parallel chain transaction of a corresponding parallel chain from a first main chain block according to stored registration information of a plurality of first parallel chain nodes, the temporary parallel chain block comprises a first block hash and a block height corresponding to the main chain block, and the registration information comprises a parallel chain name of the first parallel chain node. 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 blockchain, and in particular to a method, device and storage medium for generating a parachain block. 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 generation method and device that reduce the bandwidth of parallel chain nodes to synchronize parallel chain blocks and reduce the time-consu...
