Carrefour will use blockchain to let curious mammals know where their milk came from

It’s an evolution of another of its Blockchain-as-a-Service (BaaS) offerings, IBM Blockchain Platform, which was built using the Linux Foundations’ Hyperledger Fabric (based on Ethereum).To use IBM Food Trust, businesses pay anywhere from $110 to $11,000 per month, and when it launched, IBM claimed the platform could support even very large companies with over $1 billion in annual revenue.Carrefour was named as one of the first willing participants, and was reportedly gearing up to “convert” more than 12,000 of its stores to its new distributed ledger “ecosystem.”The idea is that an immutable, shared database for supply chain data can help enforce product quality, allowing customers to truly trust where, how, and under what conditions their fresh food is produced.Having a complete and transparent mapping of production is also thought to help navigate complicated regulatory requirements of international trade, an aspect of the technology that Macron ultimately referenced.Rival supermarket chain Auchan has also been getting in on the DLT fun.
