Abstract	As smart cities continue to be developed, network traffic surges. Although edge computing improves the quality of service by shifting computing tasks from cloud computing centers to locations closer to the edge through a multi-layer distributed computing model, there are security risks in the face of central node failures and internal malicious attacks, which make it difficult to provide stable and reliable services. In this paper, we design a trusted management model of edge device in smart city with blockchain, introducing blockchain technology into the research of smart city construction. It uses the blockchain distributed architecture and decentralization idea to realize the trusted collection and storage of sensory data. And based on this architecture, a new reputation-based PoW consensus algorithm is proposed to provide a trust mechanism for IoT devices. The algorithm greatly increases the cost of malicious attacks launched by the IoT device, effectively prevents malicious attacks on devices, and achieves trusted management of edge device behavior. The smart city application based on the proposed method verifies its feasibility, effectively prevents malicious attacks from nodes, and enhances the information security of the system. © 2022 IEEE.
