With the development of artificial intelligence, big data, IoT and other technologies, more and more data is generated and collected through traditional sensing devices or smart mobile devices.In order to improve the transmission efficiency and availability of data, the original data often needs to be initially analyzed and processed with the help of edge computing, so there will be a large amount of available data in the edge computing network, and if these data can be shared directly in the edge network, it will If these data can be shared directly in the edge network, it will greatly improve the utilization of data and accelerate the modernization process of the city.Therefore, how to securely share data among heterogeneous edge nodes is also a current research hotspot.For the problems of difficult to establish trust relationship, difficult to guarantee privacy and single point of failure of central framework for data sharing in edge computing, a blockchain-based access control mechanism is proposed and implemented in this paper.In this scheme, smart contracts of blockchain are used to manage access rights and audit data, and the decentralization and tamper-evident characteristics of blockchain are utilized to solve the single point of failure and node trust problems.
