Q&A: Walmart's Frank Yiannas on the use of blockchain for food safety - Computerworld
Once a skeptic about blockchain, Frank Yiannas, Walmart’s vice president in charge of food safety, now contends it's the perfect way to create a transparent, secure and immutable record for tracking food from farm to store shelf.
Walmart is among the most advanced retailers in deploying an IBM blockchain-based supply chain tracking system, which it hopes will bring more than 100 suppliers into an immutable, transparent ledger that can track food from farm to store in seconds.
Last week, Walmart called on all of its suppliers of leafy green vegetables to submit data to the blockchain tracking system by the end of September, 2019.
