Recent Walmart patent efforts have shown how the retail giant is studying the blockchain, and a new deposit aims to focus on autonomous delivery drones.
The application was published on August 30, specifying a system by which "stand-alone electronic devices" communicate with each other wirelessly and pass the objects carried over the other after a process identification.
After a drone travels to a specific point where another is located, they exchange authentication signals using "blockchain keys" and if the first robot successfully recognizes its "work colleague", it passes the packet. The drones would rely on a database of delivery information stored on any blockchain in which the company operates.
To identify themselves, robots use a varied means of actually sending signals from one to the other, including RFID codes, QR codes or ultrasounds, the patent application says.
In addition, each of the delivery robots can be equipped with unique features so that it can be easily identified by other drones.
For the filing, the use of automated technology is designed as a way to reduce the time to which elements of the delivery process must be "trusted". Indeed, Walmart argues that the fact that consumers should trust the delivery of their goods to flying machines "raises safety challenges" and requires a reliable system of identification for drones.
The blockchain system described in the file includes "a plurality of configured nodes to generate computational tests of the integrity of the record and the chronological order of its use for content, trade and / or as currency of exchange through a peer-to-peer network ", says the document, and" each node works in search of a difficult job test for its block. "Even the smart contracts can be integrated into this framework, according to the Walmart team .
Walmart has been actively working on various blockchain solutions for his business and has recently applied for patents on home appliance management and delivery control, among others. [19659002] Drone in a warehouse image via Shutterstock
