US multinational retail corporation Walmart has recently applied for another blockchain-related patent, this time looking to manage the use of smart appliances via blockchain technology.
The application filed with the US Patent and Trademark Office covers the use of this tech on a number of devices, including televisions, computers, laptops and portable media players.
The smart device paired with the computing system would receive a transaction request which, once accepted, transmits a configuration instruction for the appliance to be operated by the user via one or more nodes in the network needed for validation. The smart device holds the private key needed to authorize transactions.
Management of the device includes the ability to customize access and control in order to secure the system, with the blockchain server network utilizing an Internet of Things (IoT) ecosystem that allows multiple smart devices to be managed. The computer system would include a memory device to store the smart appliance’s usage data, as well as a processor capable of executing a variety of instructions.
The patent application details how the technology could be utilized in creating an entire smart home system, including control over energy and healthcare environments.
Walmart’s eclectic blockchain patents
The patent request was filed on 26 January following several other similar appeals from Walmart.
In June, the corporation filed an application for blockchain technology for use with life-saving medical wearables. The device would allow paramedics to gain information about a patients ailment should the individual be unconscious or unable to communicate their problem.
In another case, Walmart filed an application that would utilize blockchain in the receipt of goods at the point of delivery from autonomous ground vehicles, while allowing automated vehicles to have safe travel access. Walmart cites in the patent proposal that one-day parcels may be delivered to the company via automated vehicles that operate on blockchain technology.
