Chickens and eggs: Retailer Carrefour adopts blockchain to track fresh produce

The technology allows Carrefour to track and share information on how products are grown, processed and shipped.

Europe's largest retailer Carrefour SA has adopted blockchain ledger technology to track and trace chicken, eggs and tomatoes as they travel from farms to stores, and will deploy it across all of its fresh product lines in coming years.

The French retail giant said it will rely on blockchain technology developed by IBM, which is working with a number of retailers, logistics firms and growers to roll out systems to secure their global supply chains.
