NFTs, short for non-fungible tokens, are blockchain-based digital assets that represent unique ownership of items such as artwork, music, collectibles, and virtual real estate. Unlike cryptocurrencies, which are interchangeable, NFTs are one-of-a-kind and cannot be exchanged on a like-for-like basis. They have gained prominence in the art world, gaming industry, and metaverse platforms, attracting both investors and creators seeking new ways to monetize digital content.
