Data security sharing and interaction method of regulation system based on blockchain

In this paper, we analyze the business characteristics of regulation data in order to meet the application requirements of safe data storage and sharing interaction in the field of regulation and control. At the same time, we combine the characteristics of blockchain data storage, and propose a data sharing and interaction method based on blockchain regulation business, design the overall storage architecture of on-chain and off-chain data, and the smart contract interface for data interaction. Finally, the interaction process realizes the safe sharing and interaction of regulation data, and the performance of different smart contract interfaces is analyzed statistically and comparatively.
