Non-fungible tokens, or NFTs, are unique digital assets that represent ownership of a specific item or piece of content, such as art, music, or virtual real estate. Unlike traditional currencies or cryptocurrencies like Bitcoin, which are interchangeable and have the same value, each NFT has distinct characteristics that make it one-of-a-kind. NFTs are built on blockchain technology, which ensures their authenticity and provenance. This means that when someone buys an NFT, they receive a verified certificate of ownership that cannot be duplicated. This has opened new opportunities for artists and creators to monetize their work in the digital space.
