Two well-known French retailer uses the blockchain technology to track and enhance transparency of its supply chains.
After testing the technology in Vietnam with the support of the German startup Te-Food, Auchan introduced her to French, Italian, Spanish and Portuguese markets. Using this technology, all participants in the supply chain will be able to record information about products at every stage of its existence into a single, distributed and open database. Consumers, in turn, will be able to scan QR codes, which are installed on all products in the "Auchan", and get a full idea of their origin.

In Italy, the technology will be used to track tomatoes and chicken, and in Spain ― for pork and exotic fruits.
