Sony har ret åbent slået fast at de ikke som sådan planlægger at bruge NFT'er og anden form for blockchain-baseret teknologi i deres spil, noget som mange har bifaldt eftersom reaktionerne på disse teknologier i spilbranchen har været nogle lunkne.
Men noget tyder på at Sony om ikke andet har eksperimentet med disse teknologier. Et patent er nu blevet publiceret i denne måned, efter at være blevet indsendt for et års tid siden, der beskriver både NFT'er og anden blockchain-teknologi hos PlayStation-divisionen.
Selve patentet hedder 'Tracking Unique In-Game Digital Assets Using Tokens on a Distributed Ledger', og det beskrives præcis som andre har beskrevet NFT'er i spilbranchen, nemlig at kunne eje, bytte og sælge in-game items.
"The techniques and technologies described herein expand the capabilities of digital assets associated with video games, and of systems that create and manage such digital assets, by converting the digital assets associated with video games from being fungible to being non-fungible. The techniques and technologies described herein expand the functionality of digital assets associated with video games, and of systems that create and manage such digital assets, by tracking a history of the digital assets. Tracking the history of the digital assets can include, for example, tracking when, how, and by whom the digital asset was created, used, modified, rented to, rented by, sold to, purchased by, licensed to, licensed by, exchanged to, exchanged by, and / or other actions."
