The largest American retailer Walmart filed a patent application for a new blockchain system for automatic delivery of parcels by drones.
The application describes the process of transferring the goods from one" stand-alone electronic device " to another. According to the document, after the identification and exchange of the so-called "blockchain keys" drones will send each other a parcel. The system will use the data stored in the distributed registry.
It is reported that to recognize each other's drones can use different technologies: RFID tags, QR codes and ultrasound.
"A set of nodes configured to generate computational proof of record integrity and chronological order of use for content, trade, or as a peer — to-peer exchange currency," the blockchain system is described in the patent application.
Walmart representatives also noted the possibility of using smart contracts in the new project.
Previously, Walmart filed a patent application with the USPTO, which describes the use of blockchain for improved parcel tracking.
