The system will ensure that all produce-related information will be open and accessible, in real-time with end-to-end traceability
Walmart on September 25 asked its suppliers of leafy vegetable produce to upload and integrate their data to a blockchain-based tracking system.
The suppliers have time until September 2019 to put in place the systems to ensure all produce-related information will be open and accessible, in real-time with end-to-end traceability. In case, there is a problem with a certain batch of produce, Walmart will be able to trace the entity that has dealt with the produce all the way from the farm to someone’s table.
This blockchain network is the result of a year’s collaboration between Walmart and IBM to digitise the food supply chain process. According to a report by TechCrunch, the network is called IBM Food Trust Solution. It was built using IBM’s Blockchain Platform and is run entirely on IBM Cloud.
Most food supply chains are manually run and take roughly seven days to trace the source of produce. But TechCrunch’s report said with IBM’s Food Trust Solution, the trace time can be reduced to a mere 2.2 seconds.
