European supermarket giant Carrefour has become the latest food purveyor to sign on to IBM’s food-tracking blockchain technology.

Although the IBM Food Trust was officially announced Monday, many big-name enterprises have already signed on including Nestle, Dole Food, Tyson Foods, Kroger, Unilever and Walmart, which recently set a one-year deadline on its produce suppliers to start using this IBM blockchain to track their leafy vegetables.

Carrefour is among the world’s largest retailers in the size of its chain and revenue. It has approximately 12,000 stores in 33 countries. In 2017, revenue was about $101 billion.

Purchase, N.Y.-based IBM had been testing its system for 18 months. The official launch of the platform represents one of the first examples of blockchain in widespread use addressing a business problem.

Large, small and medium-size enterprises in the food industry supply chain can join IBM’s network for a subscription fee ranging from $100 to $10,000 a month, according to a press release.
