Sony filed a patent : SUPER-FUNGIBLE TOKENS

Sony filed a patent to create “super-fungible tokens” (SFT) for video games. SFTs is a bundle of NFTs that are tied to in-game assets. The SFTs are stored and tracked on a “distributed ledger”

ABSTRACT
An electronic device and a method for implementation of super-fungible tokens for gaming is disclosed. The electronic device tracks a set of gaming assets associated with a player in a gaming application. Metadata associated with the set of gaming assets is received and a super-fungible token is created, based on a storage of the metadata to a distributed ledger associated with the gaming application. The creation of the super-fungible token corresponds to an ownership of a single gaming asset from the set of gaming assets by the player in the gaming application at a time instant. A first user input indicative of a selection of a first gaming asset is received. The selected first gaming asset is enabled and a set of second gaming assets are disabled in the gaming application. The disabled set of second gaming assets correspond to gaming assets other than the enabled first gaming asset.

Here’s a quick diagram of how it works…
