Grocers Adopt Blockchain

20% of Top Global Grocers will Adopt Blockchain by 2025, Says Gartner

20% of the top 10 global grocery retailers will be using blockchain for food safety and traceability by 2025, as indicated by Gartner.

Joanne Joilet, Gartner’s Senior Research Director, says –

“Blockchain can help deliver confidence to their customers, and build and retain trust and loyalty. Grocery retailers are trialling and looking to adopt the technology to provide transparency for their products. Additionally, understanding and pinpointing the product source quickly may be used internally, for example, to identify products included in a recall”

For example, Walmart now requires suppliers of leafy greens for implementing a farm-to-store tracking system based on blockchain. On the other hand, the others, like Nestlé and Unilever, are also using technology to trace food contamination.

Joliet says –

“As grocers are being held to higher standards of visibility and traceability, they will lead the way with the development of blockchain, but we expect it will extend to all areas of retail. Similar to how the financial services industry has used blockchain, grocers will evolve best practices as they apply blockchain capabilities to their ecosystem. Grocers also have the opportunity to be part of the advancement of the technology as they develop new use cases for important causes for health, safety and sustainability.”


Recently, Carrefour announced that it is willing to track 20 of all in-house products on the blockchain by the end of 2019.

Emmanuel Delerm, the Blockchain Programme Director at Carrefour, told Hard Fork –

Currently, it uses the technology to track 20/300 Carrefour-branded products through the supply chain and plans to add 40 more in the coming months, Carrefour Blockchain Programme Director

The firm has applied blockchain pilots in six countries, including China, Spain, Italy, and France. Consumers can access information about the product’s origin which they’re just by scanning a QR code on the packaging.

Delerm said –

“When we tested this feature in China – we tested it with a Chinese pomelo – we got incredible figures. Customers scanned one out of two or three pomelos to check where the fruit was coming from”

He added –

“In countries like Spain or Belgium, we noticed that customers scanned only about 1/20 pomelos.”
