Blockchain-based data checking system, method, computing device and storage medium

Abstract

This specification provides a blockchain-based data checking system, method, computing device, and storage medium, wherein the blockchain-based data checking system includes: a first checking system, a second checking system, and the first checking system on the blockchain. The blockchain node and the second blockchain node; the first verification system is configured to collect the first business data according to preset conditions and generate a first verification file, and send a verification request to the second verification system; the second verification system is configured To receive the verification request, check the first business data with the second business data in the local database, generate a verification result notification and send it to the first verification system, and send the successfully verified second business data in the local database to the district The first block chain node on the block chain; the first verification system is also configured to receive the verification result notification, and send the first business data that has been successfully verified to the second block chain node on the block chain.

Description

technical field [0001] This specification relates to the field of blockchain technology, in particular to a blockchain-based data verification system, method, computing device and storage medium. Background technique [0002] With the development of Internet technology, financial institutions and trading platforms are becoming more and more diverse. Therefore, the transaction data between financial institutions or between trading platforms and financial institutions needs to be checked regularly, so as to discover the data of the same transaction in different institutions difference. [0003] In the prior art, the data processing method between agencies is that agency A packages the transaction data generated within a preset time period and sends it to agency B, and agency B checks the data in the file package, but the method adopted in the prior art is: The development cost of the verification method is high, which involves data export from the core business system, file t...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the data processing method between institutions is that institution A packages and sends the transaction data generated within a preset time period to institution B, and institution B checks the data in the file package, but the method used in the prior art The development cost of the verification method is relatively high, involving data export from the core business system, file transfer, and comparison with the data of the core business system. If a large amount of transactions occurs during the verification cycle, it will take a long time to complete the entire process. The timeliness is poor, it is difficult to achieve real-time or punctual verification, and the data that is verified through the existing methods, if there is a dispute in the future, there is a lack of an arbitration mechanism that can be recognized by both parties
