the "National Data Infrastructure Construction Guidelines" released by the National Development and Reform Commission, the National Bureau of Statistics, and the Ministry of Industry and Information Technology clearly propose the use of blockchain technology, encryption technology, and smart contracts to build a trusted data circulation system.

The goal of the plan is to achieve a large-scale trusted data circulation pattern covering large and medium-sized cities in the coming years.
