Japanese entertainment company Sony has recently filed a patent application in the US for “super-fungible tokens” specifically designed for gaming purposes. The application, which was initially submitted in 2022, was made public at the end of February. The document outlines Sony’s plans to create an electronic device that can track gaming assets and generate a new type of super-fungible token. According to the document, this involves receiving metadata associated with a set of gaming assets and then using it to create a super-fungible token on a distributed ledger connected to the gaming application. This token represents the ownership of a single gaming asset within the set at a specific moment in time. The patent application suggests that the super-fungible token can function as a collection of non-fungible tokens (NFTs) grouped together. Although the document does not specify which blockchain will store the metadata, it does mention Ethereum as an example. This news follows Sony’s previous patent application for an NFT framework that enables the transfer and use of digital assets across different game platforms. Additionally, in 2022, Sony invested $1 billion in Epic Games, a major player in the video game industry, as part of its strategic expansion into the gaming metaverse.
