US retail giant Walmart has filed an application for a patent regarding blockchain-backed drones.
The application, entitled ‘Cloning Drones Using Blockchain’, was made in January and was published by the United States Patent and Trademark Office at the start of this month.
It marks a return to an interest in blockchain-backed drones for the company, which previously applied for a patent for a blockchain-based drone package delivery system in 2017.
Walmart has also made several other patent applications regarding drone technology, whilst it made its interest in blockchain clear earlier this month when it emerged it had applied for a patent regarding a new cryptocurrency.
The patent claims that blockchain will be used for the transmission to other drones of information such as drone identification numbers, flight heights, speeds and routes and battery information.
Walmart said in the application: “A blockchain ledger may store any kind of information that may be stored in any other format or medium, for example, a large list of instructions of different types, navigational information, and maps. In such a way, a same software profile may be deployed across the cloned drones.”
The patent application is the first step in what will be a long application process for the company.
