Government Data Sharing based on Blockchain

Abstract

With the development of smart city, the cooperation between government sectors is becoming more and more frequent, breaking the information island and big data sharing has become an inevitable trend. The traditional way of government data sharing is mainly based on one unified data center, which has high construction cost and maintenance cost, and fails to fully consider the sectoral interests, authority, security and traceability, so there are still many barriers in government data sharing. Taking advantage of the features of blockchain technology, such as distributed ledger, smart contract, data trust and traceability, this paper proposes an application model of government data sharing based on blockchain, which uses a unified data sharing model and autonomous authority management to provide efficient and safe bus service for distributed government big data sharing.
