What exactly is the food blockchain?
Blockchain is a technology used to digitally store and send secure, tamperproof information. It is a database which contains a record of all data exchanged between its users (producers, processors and distributors) since it was created. When applied to the food sector, blockchain technology can be used to store information about a given product: where it comes from, where it was reared or the methods used to produce it. It guarantees consumers complete transparency regarding the channels through which products have passed.
Why do we need to take action?
Consumers always want more transparency and assurances regarding the products that they purchase. Both producers and retailers need to forge relationships based on trust with consumers. The food blockchain meets this customer requirement. By scanning the QR code on a product's label, consumers can access transparent information about it on their smartphone.
Is this really so new?
Until now, blockchain technology has not been used for food. Carrefour is a pioneer in this regard and in March 2018 became the first retailer to use blockchain technology for food products, applying it to its Carrefour Quality Line Auvergne chicken.
What is the long-term aim?
Between now and the end of the year, Carrefour's aim is to gradually roll out blockchain technology to other Carrefour Quality Lines: Auvergne chicken, Cauralina cored tomatoes, Loué farmhouse eggs, PDO Rocamadour cheese, Gillot milk, Norwegian salmon and Noël fattened chicken. Carrefour would like to have applied this technology to all of its Quality Line food products by 2022.
