NFTs are unique digital assets, like artwork and sports trading cards, that are verified and stored using blockchain technology, but critics see them as overhyped and potentially harmful to the environment given the energy-intensive nature of cryptocurrencies.
Non-fungible tokens can digitally represent any asset, including online-only assets like digital artwork and real assets such as real estate. Other examples of the assets that NFTs can represent include in-game items like avatars, digital and non-digital collectibles, domain names, and event tickets.
