Carrefour supermarkets credit blockchain for improved sales

French retail giant Carrefour has noted increased sales of selected products, citing blockchain technology as the catalyst, Reuters writes.

Carrefour joined IBM Food Trust to track 20 products from farms to store shelves using distributed ledger technology, including chicken, eggs, raw milk, oranges, pork and cheese. 

The company has noted a positive impact on pomelo fruit sales. Similarly, Delerm pointed out, “We had a positive impact on the chicken versus the non-blockchain chicken.”

“You are building a halo effect—‘If I can trust Carrefour with this chicken, I can also trust Carrefour for their apples or cheese,’” said Carrefour’s blockchain project manager Emmanuel Delerm.

Carrefour is planning to add 100 more items on the blockchain this year, including some baby products.

Carrefour is still deciding how to track fruit and vegetables sold loosely as they may come from different farmers, some of whom are reluctant to share detailed information about their crop-management.
