Sony files two blockchain patent applications
Sony has filed two patents for methods of hosting and maintaining blockchains, suggesting that the tech giant is planning to launch hardware in the future.
The two filings are titled ‘Electronic Node and Method for Maintaining a Distributed Ledger‘ and ‘Device and System‘, and are the first hints that Sony is working on launching its own blockchain-related hardware.
The application for Electronic Node and Method for Maintaining a Distributed Ledger reads:
“An electronic device for maintaining a distributed ledger, which is maintained by multiple electronic nodes, wherein the distributed ledger includes multiple blocks which are associated at least with one of the previously recorded blocks and wherein a block can be added to the distributed ledger based on a mining process, has circuitry configured to perform a mining process of a block to be added to the distributed ledger, wherein the mining process by at least a part of the multiple electronic nodes includes compressing data of the block to be added to the distributed ledger.”
Secondly, the Device and System application reads: “A device for accessing a distributed ledger is provided. The distributed ledger is maintained by a plurality of virtual nodes. The device has a circuitry, which is configured to access the distributed ledger through at least one virtual node of the plurality of virtual nodes.”
Sony previously filed a patent request for a way to use blockchain to store digital rights data, stating that current digital rights management (DRM) solutions are too unreliable.
“If the rights locker provider or system goes out of business or otherwise fails, the user loses all the acquired content,” the company said. “A DRM computer system would verify the rights in the blockchain and then decrypt the media when needed.
“This computer system can take different forms, including a ‘DRM’ agent residing on a user’s device.”
