Sony has filed a new patent that suggests it’s looking into NFTs and blockchain technology. Sony Interactive Entertainment is actively exploring using non-fungible tokens and blockchain in games, which allows users to buy and sell in-game artwork and digital assets.
As reported by Gamesual, the patent is titled “Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger”. It was originally filed last year but only published four days ago. The system mentioned in the patent could be used to verify the authenticity of digital assets used by content creators and top players, which can then be bought, sold and rented to other users.
The patent filed by Sony goes into some detail about how this system might work:
“A system and method for tracking digital assets associated with video games. The digital assets may be in-game digital assets, such as in-game items or characters. The digital assets may be video game digital media assets representing moments of gameplay of a video game, such as video clips or images. The digital asset is created, and a distributed ledger tracking a history of the digital asset is created and stored across devices.”
The patent adds that unique tokens generated for digital assets may include metadata to identify the properties of it:
“A unique token for the digital asset can include a unique identifier and metadata identifying properties of the digital asset. Changes to properties of the digital asset, such as ownership, visual appearance, or metadata, can be identified in a request to update the history. A new block can be generated for, and appended to, the distributed ledger identifying the changes to the history of the digital asset. The new block can include hashes of previous blocks.”
A new loyalty program called PlayStation Stars came under fire earlier this year when many users noted that it could be linked to NFTs and blockchain technology – something that is still a hotly debated topic in the gaming community. However, Sony were quick to dismiss these claims, stating that they weren’t NFTs.
Whatever this Sony NFT project is, it’s unlikely to be linked to PlayStation Stars and could take the form of its own program. PlayStation has yet to provide further comments on the patent.
