Abstract: This article aims to solve the existing problems of power data asset management in data sharing, data transaction, data security, etc., so as to achieve intelligent control and realize value of power data asset. In the first sector, we discussed data collection and transaction of present power system, and its defects on data management. We then discussed applications of blockchain-data-control and put forward the concept of interactive double-chained blockchain based on principles of genetics. The mechanism and control strategy of interactive double-chained blockchain is analogous to process of transcription, interpretation, expression & regulation and reverse transcription of gene heredity. Interactive double-chained blockchain platform can solve security and complexity issues during power system data transactions, while offering effective scheme to the platform structure.

Key words: interactive double-chained blockchain, data assets, power internet of things, scalable Byzantine consensus protocol
