A Multinational Retail Giant Files For Blockchain-Based Drones Patent
As evidenced by a recent patent application, there’s been a resurgence of interest in blockchain-based drones by the retail giant Walmart.
The United States Patent and Trademark Office received an application titled “Cloning drones using Blockchain” from the company at the start of 2019 and published the subsequent patent on August 1 of the same year. This patent, concerned with the blockchain-based coordination system of a UAV (unmanned aerial vehicle), was also released on the same date as Walmart’s digital currency patent application.
This patent is not the company’s first involvement in blockchain-backed drone technology. Among others, an application of a patent for blockchain-based drone package delivery systems was also submitted by Walmart in 2017.
Blockchain technology, as per the patent, helps in the transfer of information like drone ID numbers, flight altitude & velocity, flight routes, battery status, load capacity, etc. from one drone to another. This transmission of information can be based on the intermediate location between drones.
The patent claims that the advantages of blockchain lie in data integrity:
“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, the same software profile may be deployed across the cloned drones.”
The listed valuable uses also include communication and coordination. Operational parameters can also be executed without being compromised by securing the information on a decentralized ledger.
However, issuing a patent and merely publishing the patent application are two different things. The application is only the beginning of a big process.
Earlier this month, Walmart’s interest in blockchain technology caught everyone by surprise, publishing a patent for a cryptocurrency, similar to that of Libra by Facebook.
