Abstract：To solve the problems of low efficiency and difficulties of tracing process, online supervising and data updating in the current control mode of stability control system, the blockchain technology was embedded in the control framework of stability control system. Taking the advantage of blockchain technology, the data information involved in each stage of the control process of stability control system was packaged and distributed, so that the key data information could be traced and not be tampered to control the whole life cycle control process. The management and operation of stability control system and the control application architecture were constructed based on blockchain. The block data structure was given, and the delegated proof of stake (DPOS) was adopted. Based on the control project practice of a stability control system in progress, the application platform of stability control system management was developed based on blockchain. The results show that in the operation and maintenance management stage, the policy file and setting value file can realize the real-time supervision of online storage and consistency inspection, and the level of intelligence and automation of stability control system is further improved.
