Will Walmart Use Blockchain-Based Delivery Fleets?

Retail giant Walmart (WMT) may be the next major traditional business looking to get involved in the world of blockchain and cryptocurrency. Last month, the company revealed plans for a new, cryptocurrency-powered payment system for vendors and customers. Now, new patent filings show that the company may also be looking to utilize blockchain technology to help revolutionize a system of automated delivery cars or trucks, according to Coindesk.

Application Filed in October

Beyond that, a blockchain-powered distributed network could be highly useful for tracking and authenticating goods for delivery, too.

In describing the proposed blockchain delivery system, Walmart wrote that “when a customer interacts with a product, the customer is permitted to do so via a private or public authentication key,” much like for a digital currency. “In response, new blocks may be added to subsequent root blocks, which will contain information relating to the date and time a product delivered by the AGV was accessed, as well as the authentication key that accessed the product.”

Aside from the primary goal of security, Walmart indicated in the application that the system could also “increase customer loyalty” as a result of “significant convenience” relative to other modes of delivery. Further, the company…
