Parallel chain mining consensus method and device and storage medium

Abstract

The invention provides a parallel chain mining consensus method and device and a storage medium. The method comprises the steps that first calculation result information is generated according to a plurality of transactions to be consented; packing the first calculation result information into a first mining transaction and storing the first mining transaction into a local database for query or data recovery; packing according to the first calculation result information to generate a first voting transaction and sending the first voting transaction to the corresponding main chain node, recording the first calculation result information on the main chain through the main chain consensus, verifying whether the first calculation result information which is not less than a first threshold number in the first calculation result information recorded by the main chain is the same or not, and generating a verification result; and synchronizing the verification result, and writing the verifiedfirst calculation result information into the parallel chain. According to the method, local query and other functions are provided for a parallel chain consensus mechanism through atomic local data backup, and parallel chain nodes are attracted to participate in parallel chain consensus through mining excitation.

Description

technical field [0001] This application relates to the technical field of blockchain, and specifically relates to a parachain mining consensus method, equipment and storage medium. Background technique [0002] A parachain is a blockchain that relies on the main chain. The parachain has its own blocks and nodes, and its block transactions are completely transparent to the main chain. Due to the high cost of consensus and other reasons, the existing parallel chain mechanism usually does not configure a consensus mechanism, resulting in the lack of security of the block after the nodes of the parallel chain generate blocks, and it is difficult to solve possible forks and other problems. [0003] In response to the above problems, the applicant proposed a parachain consensus mechanism through the main chain to perform parachain consensus in a patent previously applied for, which can solve the above problems to a certain extent, but there are still parachain nodes that do not ca...

AI Technical Summary

Problems solved by technology

Due to the high cost of consensus and other reasons, the existing parallel chain mechanism usually does not configure a consensus mechanism, resulting in the lack of security of the block after the nodes of the parallel chain generate blocks, and it is difficult to solve problems such as possible forks

[0003] In response to the above problems, the applicant proposed a parachain consensus mechanism through the main chain to perform parachain consensus in a patent previously applied for, which can solve the above problems to a certain extent, but there are still parachain nodes that do not carry out atomicity. local data backup, resulting in the inability to perform convenient local queries

In addition, it also leads to the increase of the workload of the parachain nodes participating in the parachain consensus, but it is difficult to attract the parachain nodes to participate in the parachain consensus due to the lack of incentives
