A blockchain-based data sharing and exchange system and method

Abstract

The invention discloses a block chain-based data sharing and exchange system and method. The system includes a data sharing and exchange center, a front-end system and a block chain basic platform. The data sharing and exchange center includes the data sharing and exchange control system, data resource center and client; the front-end system includes the data acquisition system, the sharing and exchange module and the feedback module; the blockchain basic platform includes the alliance chain module and the data sharing and exchange management module, and the alliance The chain module is responsible for the credibility configuration of smart contracts and verification nodes, and verifies the smart contracts generated during the data sharing and exchange process. The data sharing exchange center communicates with the front-end system and each front-end system through the alliance chain. The invention solves the credit problem and incentive problem of data sharing and exchange in a multi-party participation environment, ensures safety and reliability, is conducive to promoting the enthusiasm of users to release and update shared and exchanged data, and can realize the guiding effect on user decision-making.

Description

technical field [0001] The invention relates to the field of data sharing and exchange, in particular to a blockchain-based data sharing and exchange system and method. Background technique [0002] In recent years, the national informatization construction has been continuously improved and developed. Many units and departments have established their own business application systems. The key cross-departmental business systems have been designed as independent systems within the department. The joint construction and sharing of information resources cannot Reached a consensus that the potential "information island" risk is prominent, and business collaboration capabilities are greatly constrained. There are many reasons for information islands, which can be summarized into three aspects: first, users have independent and heterogeneous information management systems, which are difficult to communicate with each other; second, data coding standards and interface specification...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects in the current informatization construction process that each unit is self-contained, the awareness of active data sharing is weak, the leading unit cannot grasp the information sharing situation as a whole to make corresponding decisions, and the security of the data sharing and exchange process is not guaranteed, etc., to establish a Based on the blockchain-based data sharing and exchange mechanism, through the statistical measurement of the data sharing of each unit, the quantification of data quality is achieved, the value of data is clarified and the security of data exchange is guaranteed, and the awareness of sharing is encouraged to achieve mutual benefit and win-win results
