Walmart Embraces Blockchain Technology for a Better Package Tracking System

Walmart seems to be working again with the revolutionary blockchain technology according to a recent application published on July the 5th. The patent is entitled ‘Delivery Reservation Apparatus and Method,’ and it allows to manage package reservations if the purchaser is not able to receive it.

This is one of the latest patents uploaded by the retail giant that is trying to reduce costs and have a better service by implementing blockchain technology. In the past, Walmart submitted an important number of patents related to this technology.

The company is trying to automate all the elements of the delivery process as much as possible. But most of the investments that Walmart has made were focused on food supply chain tracking.

The filing shows a system of delivery lockers that are located at a person’s home, a transportation hub or any other location, that would allow the users to have the items safeguarded until he comes back home and can sign for them. Blockchain would be used in order to track which lockers are occupied and which ones are free to use.

Walmart wrote about this system:

“Each space on the docking station has a corresponding capacity unit for each location on the docking station. The transactions for the capacity units are tracked in a ledger, with available capacity units indicating an open location on the docking station or contracted out capacity units indicating that either the location has a locker secured thereto or that the location is reserved for a future delivery. “

Some of the docking stations will be using a blockchain reservation system, and because of it, each docking station can be a node within a blockchain network.

As the application talks about a ‘public ledger’ we can think that the system would be open and accessible to some extent. There are other blockchain networks that are totally closed and that do not allow non-authorized third parties to access the network. This may suggest a possible integration with other companies and operators of the docking stations.

Other important retailers around the world are also using the technology to improve their services. We can mention the Chinese Giant JD.com or the European Carrefour.
