Data processing system based on block chain

Abstract

The invention discloses a data processing system based on a block chain. The system comprises: an infrastructure layer consisting of a portal, a client and N servers based on peer-to-peer network communication. Each server establishes an initial block of a block chain and maintains a block chain. A processing layer is used for realizing the data interaction and processing between the system application layer and the infrastructure layer. The layer comprises a data uploading module, a single block verification module, a data query module, and each server of the infrastructure layer in the periodic block chain verification module periodically verifies the correctness of the self-maintained block chain. The application layer is used for calling the module of the processing layer according tothe request of the user, and realizing the access control in this layer. By utilizing the embodiment of the invention, the system query data efficiency and the resource utilization ratio are higher than those of 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
