Walmart announced that it plans to integrate a blockchain-based tracking system built in collaboration with IBM by September 2019.
According to a news release, any company working with Walmart must work with the IBM Food Trust network by that time. Company representatives said the blockchain platform will make it easier for Walmart to source food items quickly.
The move comes after an E. coli outbreak originating in Arizona earlier this year. Walmart vice president of food safety Frank Yiannas said in a news release that it was difficult for customers to confirm where exactly their produce was grown, and, by using blockchain, the company can better protect customers.
