Today Internet of Things industry is growing rapidly, various applications of Internet of things has penetrated the dribs and drabs of people’s life, but the heterogeneity of the Internet of things and massive amount of data lead to share data between different organizations is very difficult, and because of that people want to find the value of behind the data mining and collaboration between different equipment becomes difficult. Blockchain can establish trust between different parties, It does not require to rely on a unique trust institution, the data is managed by multiple parties which can only be restricted from being deleted, it is very conducive to improving the existing purchase model of the Internet of Things. Therefore, this article is based on the regional blockchain technology to study the Internet of Things device management and data sharing, and theoretically proposes a set of regional blockchain technology based IoT management system. Firstly, this paper summarizes the main research contents, including the relevant background and current situation of the Internet of things and area block technology. Secondly, it introduces and discusses the different technologies adopted by different area chain platforms, and successively studies the design scheme of consensus algorithm, network topology, ledger, chain code, device end and management system. Then the realization of each module is completed according to the design scheme, and the feasibility of the system is proved theoretically.
