Walmart, a US-based supermarket chain, is worried about the safety and fitness of its manna products such as lettuce and other foods, and believes the technology can help. So it suggests to its suppliers to adopt blockchain technology (combined with its help IBM) to monitor shipments of products.
The safe ledger of the blockchain will make it difficult for the final recipient, that is, the customer, to see the exact route of each product from the moment it leaves the field until it reaches the shelves of each store. In this way, when there are damaged products, it will be possible to locate its source in seconds to control the entire batch with which it was transferred.
But the blockchain technology is not just for Walmart. Ideally, the customer will be able to identify the path that has been crossed by each food he is buying, offering him the confidence that it is something of a quality and fresh.
Walmart propose presently to its suppliers the technology of the blockchain, but in the short term it will require it. It awaits the adoption of technology by all its partners until the end of summer of 2019. Walmart believes that in this way, the process of recalling products will be much faster, preventing the sale of spoiled food.
This is not the first time that such a big chain asks for the use of the blockchain, but it is certainly the first time that such a short run is required. Since the technology will be used and reliable, it could give a significant boost to the blockchain so that it can be used by other companies as well.
