During the epidemic, the Changan Chain privacy computing platform built by the integration of the independent and controllable blockchain software and hardware technology system Changan Chain and privacy computing was applied to the Beijing cold chain food traceability platform to accurately control millions of tons of imported cold chain food, and achieve “materiality”. , people, vehicles, and warehouses” data information can be traced and locked in the whole chain, and the risks can be located at the first time, so as to build a strong defense line for cold chain food safety.

Huang Jin, director of the Solutions Department of Beijing Microchip Blockchain and Edge Computing Research Institute, introduced that in order to strengthen the supervision of imported cold chain food, Beijing launched the construction of a traceability platform for imported cold chain food in September 2020, which was officially launched on November 1, 2020. Launched “Beijing Cold Chain” to realize the electronic traceability management of imported refrigerated and frozen meat and aquatic products, and realize data connection with the national cold chain food traceability platform. At present, Beijing’s imported cold chain food can be accurately tracked and clearly positioned to display information such as food importing countries, food batches, and food circulation statistics.
The technology of tracking and locking imported cold chain food, precise supervision and prevention and control is called Changan Chain, which is an independent and controllable blockchain software and hardware technology system.
As of July 5, the Changan Chain privacy computing platform has connected to 27,100 enterprises, recorded 95,000 imported cold chain food varieties, 419,000 commodity batches, and 1.52 million tons of circulating products, involving 126 countries and regions and China In all provincial administrative regions, the average daily circulation of products is about 470 tons.
