Data synchronization method based on blockchain application system, middleware and system based on blockchain application system

Abstract

The invention provides a data synchronization method based on a blockchain application system, blockchain middleware and a data synchronization system based on the blockchain application system, and relates to the technical field of data processing. The method comprises the steps that access to a bottom-layer blockchain of the blockchain application system and access to a synchronous database areencapsulated, and a uniform interface of the access to the bottom-layer blockchain is provided; when transaction of an upper chain succeeds, transaction data information in a bottom-layer block of thebottom-layer blockchain is updated to the synchronous database, so that the consistency between the bottom-layer blockchain and the synchronous database is maintained; the transaction data information in the bottom-layer block of the bottom-layer blockchain is stored. According to the data synchronization method based on the blockchain application system, the blockchain middleware and the data synchronization system based on the blockchain application system, the uniform access API of the bottom-layer blockchain is provided by building the blockchain middleware, and the synchronous database is built at the same time to achieve direct mapping of data in the bottom-layer blockchain to the synchronous database, so that it is achieved that the business requirements of application systems arecompleted by querying the synchronous database respectively.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to the access technology of the blockchain application system, specifically a data synchronization method based on the blockchain application system, blockchain middleware, and a blockchain-based application system. Data synchronization system. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Application systems based on blockchain technology generally use blocks to store transaction data. Each block has the same data structure, and its data structure is relatively simple. A growing blockchain is formed by serializing each block. Although the bottom layer of the blockchain technology also provides interfaces for data operations, these interfaces are relatively si...

AI Technical Summary

Problems solved by technology

When encountering an application system implemented with blockchain technology as the core, access to the data in the block will encounter various discomforts, not only the unsuitability of the development model, but also the fact that blockchain data access cannot provide similar databases issues such as high availability

On the other hand, the application system based on blockchain technology is an asynchronous system. Changes in the data on the chain will not be actively notified to the associated upper-level applications. Only when the upper-level applications actively query the data will the data changes be discovered, resulting in real-time Interaction response is not timely
