The retail giant Carrefour, based in France and operating in over 30 countries, is implementing a blockable food tracking platform based on Hyperledger in its Spanish network, according to a press release on Tuesday 20 November.
The food traceability solution, initially developed by the US technology company IBM, will be used to track free-range chickens labeled as "Calidad y Origen" ("Quality and Origin") raised in the northern region of Galicia without antibiotic treatment. Each package in the Spanish network will be marked with a QR code that provides detailed information on the date of birth of the chicken, the type of feed, the date of packing and more.
In the press release, Carrefour writes that blockchain is a key technology for supply chains, as it provides greater transparency and allows customers to review the entire distribution process. In the near future, the company plans to extend the use of decentralized technologies, implementing them to all food products of the "Calidad y Origen" line.
As reported previously by Cointelegraph, at the beginning of 2018 Carrefour has already tested the detection of blockchain for French poultry, expressing its commitment to decentralized solutions.
In October, the retail giant announced that it will join IBM's blockchain-based Food Trust created in 2016. Since launching the trials in August, the program has been reached by leading retailers and businesses, such as Nestle SA, Unilever NV and Walmart.
Other companies with large supply chains have often applied blockchains to increase transparency, reduce costs and reduce time spent on food delivery. For example, Walmart uses a farm-to-store blockchain tracking system for its leafy green vegetables, while the US fast-casual salad chain Sweetgreen plans to map its salads in the same way.
In addition, the four largest agricultural companies in the world, mostly known as ABCD, use blockchain and artificial intelligence (AI) to automate processes of post-trade execution of cereals and oilseeds, considered a highly manual and expensive part of the chain supply.
