IBM has proposed blockchain technology to solve Wal-Mart’s issues with identifying and containing food safety outbreaks. The proposed technology will allow Wal-Mart to track products in their supply chain from the farms and factories of their suppliers to the shelves in their stores. Currently, their supply chain management can takes weeks to identify and remove products that are infected with bacteria such as salmonella. The lengthy process significantly impairs Wal-Mart’s ability to protect their customers resulting in damages their brand image.
Not only does IBM’s proposed blockchain technology benefit grocery retailers such as Wal-Mart, but it also has the potential to benefit international shipping. IBM pitched their technology to Maersk, a global shipping giant, as a method to decrease the cost of maintaining the paperwork required to import and export goods. Processing the paperwork for the shipment of goods usually includes around thirty people between customs, tax officials, and health authorities. A distributed ledger technology can help to expedite the process reducing their paperwork costs that currently equals the cost of shipping the physical containers. The blockchain can also reduce fraudulent tampering with bill of lading documents reducing the frequency of stolen or counterfeit goods.
