Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings.

[0042] In today's era, the Internet industry is developing rapidly, and digital transformation has become an inevitable trend of social development. Big data, cloud computing and other technologies have become the most familiar technology representatives, and the value of data is getting higher and higher in people's minds. Government departments, various types of enterprises and even individuals regard data resources as an important part of realizing their own competitiveness. The main reason is that big data can use various data management technologies and analysis algorithms to comprehensively process massive data, quickly draw rules, obtain valuable intelligence, and realize intelligent decision-making. Breaking through data barriers, realizing data sharing, and obtaining more valuable data intelligence has become an urgent problem to be solved by various governme...

Abstract

The invention belongs to the field of resource aggregation, and particularly relates to a block chain technology-based data sharing solution, which comprises the following steps of: data model architecture design; business intelligent contract design; authority management and identity authentication design; access control mechanism design; data storage structure design. According to the multi-layer block chain model supporting massive data hierarchical authorization transactions, an offline storage mode is adopted, so that the storage space consumption of the block chain is greatly reduced. Comparison experiments verify that the Ethereum data model has great advantages in the aspects of data storage and access control compared with bit coins. An alliance chain consensus algorithm based ona message queue kafka and a private chain consensus algorithm based on an improved PBFT algorithm are provided.
