Industrial Internet of things (IIoT) deploys a large number of smart devices to obtain industrial data, which will be transmitted to cloud for analysis to improve industrial productivity. The management of large‐scale devices is complicated, and it's also a challenge to choose a high‐quality cloud service for data analysis as the number of service with similar functions increases. To address these issues, we propose a reliable fog‐cloud service solution with blockchain‐based fog‐cloud architecture. In fog layer, we build a management blockchain between fog servers and design a management method for industrial devices; In cloud layer, we construct a service blockchain between cloud service providers to form an open “service market”. Quality of service and reputation based matching algorithm and reputation‐based consensus algorithm are designed. The simulation results show correctness and efficiency of algorithms, and validate effectiveness of our proposed solution.
