First of all, by using all the data chain strips in the blockchain for prediction and analysis, the regulator can discover and prevent possible systematic risks in a timely manner, and the decentralized characteristics of the blockchain can eliminate the information islands in big data risk control and improve risk control through information ****sharing.

Secondly, the distributed database of blockchain can improve the problem of poor quality of big data risk control data, making it possible to solve the problems of diversified data formats, fragmented data forms, missing valid data and incomplete data content.

Finally, blockchain can prevent the problem of data leakage. As the blockchain database is a decentralized database, any node's operation on the data will be discovered by other nodes, thus strengthening the monitoring of data leakage.
