Non-fungible tokens are a form of digital asset that is unique. They are used to represent ownership of an item on the blockchain. Unlike fungible tokens, one non-fungible token cannot be substituted for another. They are commonly used to represent ownership of digital items like rare collectibles, in-game items, digital work of art, virtual cards, and even physical assets like land and cars. They can also represent a specific individual, such as a celebrity or an athlete, as well as provide access to exclusive content and experiences.
