PlayStation maker Sony has been exploring the use of NFTs in games

It looks like Sony Interactive Entertainment, the Japanese gaming firm behind PlayStation, is exploring the use of NFTs and blockchain tech in games. According to a newly published patent, the company is looking to track in-game digital assets using a distributed ledger. 

The patent was registered last year but was only published in November 2022. Titled "Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger", the paper describes a system and method for tracking digital assets in video games. 

According to the filing, digital assets may refer to in-game items or characters, as well as gameplay moments such as video clips or images. There are no Web3 terminologies in the document. But it's easy to tell that the entire system is powered by blockchain tech. 

For instance, the patent describes that once a digital asset is created, a distributed ledger (a.k.a. blockchain) tracking the history of that asset will be created and stored across devices. This asset could also be tokenized, giving it a unique identifier and metadata - similar to how NFTs work today. 

"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," wrote Sony in the filing. 

It remains to be seen whether the gaming giant will develop its own blockchain network to track in-game assets. If it does, it will be interesting to see if Sony implements it on existing titles or a separate NFT project down the road.
