Blockchain-based data processing system

Abstract

The invention discloses a block chain-based data processing system. The system includes: an infrastructure layer consisting of a portal, a client, and N servers based on peer-to-peer network communication. Each server establishes an initial area of ​​a block chain. block and maintain a blockchain; the processing layer is used to realize the interaction and processing of data in the system application layer and infrastructure layer, which includes: data upload module, single block verification module, data query module, and periodic blocks In the chain verification module, each server of the infrastructure layer periodically checks the correctness of the blockchain maintained by itself; the application layer is used to call the module of the processing layer according to the user's request, and implement access control at this layer. Utilizing the embodiment of the present invention, the system query data efficiency and resource utilization are higher than other block chain processing systems.

Description

technical field [0001] The invention relates to the field of anti-tampering data, in particular to a blockchain-based data processing system. Background technique [0002] The present invention adopts an emerging technology——block chain technology as the underlying architecture, which is used to realize data tamper-proof. [0003] At present, there are two main ways to realize the data tampering system based on the blockchain. One is to develop on the public chain platform represented by Ethereum, and store the data or the hash value of the data in the public chain; the other is to use The consortium chain represented by Hyperledger serves as the underlying architecture to store data. [0004] There are the following problems in storing data on the public chain platform: (1) If all the data is stored in the platform, the overhead will be too high; (2) If only the hash value of the data is stored in the platform, the integrity of the data can be verified (3) The smart contr...

Problems solved by technology

[0004] There are the following problems in storing data on the public chain platform: (1) If all the data is stored in the platform, the overhead will be too high; (2) If only the hash value of the data is stored in the platform, the integrity of the data can be verified (3) The smart contract cannot be modified, and once the application is released, it cannot be changed

However, the current data tamper-proof system based on the Hyperledger project has the following problems: (1) There are several fixed-function nodes in the Hyperledger project for the consensus of the distributed system

Therefore, projects based on hyperledgers have a high degree of centralization, and nodes with fixed functions are more vulnerable to centralized attacks; (2) hyperledgers do not consider the issue of how to restore consistency after system errors or data tampering, requiring system administrators maintain
