Mass Heterogeneous Terminal Consensus and Management Model of Power Internet of Things Based on Blockchain

As the application of the Internet of things in the smart grid, the Internet of things involves a variety of professional terminal equipment, different professional terminal equipment have different understanding of power grid resources, and use different protocols in data maintenance and transmission. This reduces the efficiency of the Internet of things and increases the construction and operation costs of the whole power grid system. In this paper, electronic voting, which is relatively recognized by most enterprises and institutions, is used to solve the problems caused by the lack of consensus and unified standards in the Internet of things. Based on the blockchain technology, an electronic voting model is designed to ensure that the voting results are untampered and auditable, and intelligent contract technology is used to ensure that the function of the voting model runs according to the logic of the code and will not be artificially interfered with. It replaces some functions such as the operation of the traditional third-party trusted organization coordination system and the counting of votes. Finally, the blind signature algorithm based on elliptic curve encryption is used to protect the privacy of voters.
