According to a new patent application, Sony Interactive Entertainment is interested in utilising blockchain technology.

According to the specifics of a patent that Sony Interactive Entertainment has submitted, the PlayStation parent company might be interested in incorporating NFTs and blockchain technology into its platform. According to Video Games Chronicle, the patent’s title is “Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger.”

The patent describes a blockchain-based system for keeping track of a unique in-game item’s history, including information about who made it, who owned it in the past, and whether it has been altered.

“People often find it meaningful to own or use unique physical items related to respected celebrities or activities,” Sony says in the background section of the digital assets.

According to the patent, notable esports players or gaming influencers might want to collect in-game objects because the tracked data could reveal, for instance, whether a player used an item to win a significant game tournament. Transferring items between games and platforms are also mentioned in the patent.

The paper states that the methods and tools described here “expand the functionality of digital assets associated with video games and systems that create and manage such digital assets by tracking a history of the digital assets.”

To date, Sony’s gaming division had little to say about NFTs in video games. However, a spokesperson clarified that the PlayStation Stars digital collectable program was “not leveraging any blockchain technologies and not NFTs” when it was first announced earlier this year.

Some of Sony’s other divisions have already released their own NFTs, such as a campaign offering Spider-Man NFTs to fans who pre-purchased tickets to Spider-Man: There is no way to return home.
