Blockchain and Data Sharing

Reading guide :

The concept of blockchain comes from 2008 In the middle of this year, Ben Cong published his paper 《 The currency : A point-to-point electronic cash system 》. In the blockchain system , Each participant maintains the ledger database collectively , We maintain data consistency through consensus algorithm , And chain data structure and complex encryption technology to ensure that the data can not be tampered with . These designs are quite different from the centralized information systems in the past , It represents a new technology paradigm . The emergence of blockchain , It is expected to make up for the congenital defects of traditional network technology in the trust mechanism , For people to share data in the digital world 、 Building trust provides a convenient way .

At present , China is vigorously promoting the implementation of big data strategy . Insufficient data sharing , It is still the biggest on the road of deep integration of big data and real economy “ Land Rover ”. The rise of blockchain , From a technical point of view, this paper puts forward a new idea to solve the problem of data sharing . This topic is based on the application research of blockchain data circulation , Collected from industry university research experts 6 An article , It shows the latest research progress in the combination of big data and blockchain in China .

Yan Shu et al 《 The application of blockchain in data circulation 》 This paper introduces how blockchain uses its technical characteristics to solve the pain point problem and application cases in the field of data circulation . On the basis of a brief introduction of blockchain Technology , This paper expounds the use of blockchain to transform the link of authorization and certificate storage 、 The main idea of data traceability and smart contract implementation , Then it combs the overall framework of data circulation . On this basis , The application examples of data circulation using blockchain in foreign countries are given , And introduces some other new data flow technologies .
