With the proposal of carbon peak, carbon neutrality, and accelerating the construction of a new power system, new challenges are posed to the distribution of the Internet of Things (DIoT). However, the current DIoT perception still faces problems such as terminal and user counterfeiting, unclear data ownership, data tampering attacks, and incomplete data sharing mechanisms. Based on this, this paper proposes a trusted data acquisition system for power distribution of the Internet of Things with on-chain and off-chain cooperation. Firstly, a data acquisition architecture based on blockchain is constructed from the aspects of terminal authentication, trusted collection, and trusted storage. Secondly, a trusted authentication method for DIoT man-machine coordination and a source data authenticity verification method for blockchain storage are proposed to provide a solid guarantee for the reliability of source data. Finally, a verifiable on-chain and off-chain collaborative storage mechanism for DIoT data is constructed to achieve efficient retrieval and authenticity verification of query results. The system provides higher reliability and sharing ability for DIoT data management and has important reference value for improving the level of power data governance.
