Documents published by the United States Patent and Trademark Office (USPTO) show that the Japanese conglomerate and technology giant Sony Corp. has applied for two blockchain patents.
Improving the blockchain-based ecosystemThese documents indicate that Sony is designing hardware specifically for maintaining the blockchain. These two patent applications are called equipment and systems, electronic nodes, and methods for maintaining distributed ledger. Both of these patents focus on the description of the device and the system used to maintain the ledger.
An application (electronic nodes and methods of maintaining distributed ledgers) describes the equipment that can be used to maintain distributed ledgers. The device will be composed of circuits that will be configured to perform the mining process, thereby adding blocks to the network. The patent explains how to compress new blocks, which can then be added to a distributed ledger. According to this patent, small blocks generated by nodes can bring greater returns to users.
The second application (device and system) describes the development of a device that can be used to access a distributed ledger and then use a system with multiple virtual nodes to maintain the ledger. By using virtual nodes, the technology attempts to ensure the integrity of the blockchain, especially when the number of devices is reduced or only a few.
Other patented blockchainThis is not the first time Sony has applied for a patent on blockchain technology.
In November last year, the Japanese conglomerate applied for a patent for the use of blockchain in education. This patent was applied for in cooperation with the US technology giant IBM. Their idea is to create a system that can store student information, such as certificates, educational experience, and so on.
Sony has also applied for a patent to create a user login system that focuses on the blockchain system. This is a blockchain-based multi-factor authentication system (MFA) that will use two independent distributed ledgers to set up the login process.
The early patents revolved around the development of blockchain-based solutions, while the latest patents focused on the development of DLT (distributed classification technology) hardware systems.
Sony is not the only major company to apply for a patent on blockchain technology. US retail giant Wal-Mart also recently applied for a patent to manage smart home appliances using blockchain technology. Last month, Bank of America (BoA) also applied for a patent for a blockchain-based system in July, which can verify data and provide information tracking by confirming the transfer of resources.
