What is a non-fungible token (NFT)? A non-fungible token (NFT) is a digital certificate of ownership that contains metadata unique to the token. Like cryptocurrency, NFTs are bought and sold through a blockchain that permanently records the transaction, but no one NFT is identical to another, unlike most crypto coins. These tokens are virtual representations of any actual or intangible asset, including artwork, music, video clips, digital trading cards, tokenized real-world assets, and virtual land. How do NFTs work? Much like cryptocurrency, NFTs use blockchain technology for advanced certification of transactions and are tradable on global platforms. NFTs break from traditional crypto is their unique attachment to a digital asset generated by a user and the subsequent auction-based sale of the NFT.
