Blockchain Technology Improves Walmart’s Food Safety, Reduces Food Loss

November 6, 2018: 12:00 AM EST

Walmart is using blockchain technology to help track and manage the chaotic and decentralized food supply system comprising producers, suppliers, and intermediaries such as processors that change constantly. Blockchain technology, like the food system, is based on a decentralized and distributed model that fits the modern food system perfectly. Each player in the network can update data, but also stops them from entering false data or making false changes. The speed with which blockchain enables companies to trace products and problems back to the source means improved food safety and less economic loss, and reduced food waste. It quickly and accurately identifies the source of a problem so that only impacted products are recalled or removed, rather than everything in the category.[Image Credit: © Tumisu from Pixabay]
