Walmart, the US retail giant, filed a patent application for blockchain technology-based drone communication system further reasserting its earlier move.
On Aug. 1, Walmart submitted its patent to the United States Patent and Trademark Office (USPTO). Drone’s operational parameters are encrypted and stored on the system as described in the filing. For those parameters to be decrypted, read, and then, configured, the information will have to be passed to another drone.
Machines will be aware of bearing and location of each other, mesh communications networks and relay messages easily as there exists a vehicle-to-vehicle communication system between unmanned drones.
Blockchain patents venture
Patenting blockchain solutions for drones has been the work of Walmart since 2017 — where specifically, the company filed an “Unmanned Aerial Delivery to Secure Location” system patent application in May 2017.
Special permissions, like whether to fly in a given flight zone, usually emanates from the validator nodes as explained in the 2017 filings to USPTO.
In order to track pharmaceutical shipments using blockchain technology, the company earlier this year entered into a partnership with American Food and Drug Administration and IBM.
Earlier this month, the retail giant also submitted its own digital currency that is based on blockchain which is an evidence of the company’s foray into cryptocurrencies.
