Problems solved by technology

Since the data provided by different users may come from different channels, the data content, data format and data quality vary widely, which brings great difficulties to data sharing, and sometimes even the data format cannot be converted or information is lost after data conversion. thorny issues, which seriously hinder the flow and sharing of data among various departments and software systems

Embodiment Construction

[0019] The purpose and effect of the present invention will become more obvious by describing the present invention in detail according to the accompanying drawings and specific embodiments.

[0020] A block chain-based data source sharing method provided by the present invention, its flow chart is as follows figure 1 shown, including the following steps:

[0021] Step 1: Connect to the database:

[0022] The data source provider connects the database that needs to provide the data source to the data platform. The data platform is a peer-to-peer network composed of all participants' nodes. Each participant's node runs the data platform on its own local platform. When the data source provider connects the database that needs to provide the data source to the data platform, it can Write the data source calling method and upload the data source information to the blockchain on the data platform. And this peer-to-peer data platform is also a channel for data source users to req...

Abstract

The invention discloses a data source sharing method based on a block chain. According to the method, a data source provider can add provided data source information in a database and a calling methodinto a block chain through an intelligent contract; a data source obtaining party can obtain related data source information on the block chain; the use right of the data can be obtained through thesmart contract of the data source provider only by performing transaction operation on the block chain, and the data source user obtains the use right and then obtains the data or obtains some statistical information of the data of the data source on the data platform in a script writing mode. According to the invention, the data source information and the calling method are linked; according to the method, the access control authority is automatically issued by using the smart contract of the blockchain, so that the data source sharing process is decentralized, the data source sharing efficiency is greatly improved, and meanwhile, through the limitation of a data source calling method, the control of a data source provider on the security of the data source is greatly improved.

Description

technical field [0001] The present invention relates to blockchain technology and the field of data sharing, in particular to a blockchain-based data source sharing method. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Completed, the consensus algorithm guarantees its consistency. A public ledger is maintained on the blockchain. The public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. [0003] A smart contract is an assembly language programmed on the blockchain. It is an automatically executable program deployed on the blockchain. A smart contract in a broad sense includes programming languages, compilers, virtual machines, events, state machines, fault-t...
