A Non-Fungible Token (NFT) is a one-of-a-kind digital token that is permanently linked to a piece and is encrypted with the artist's signature. It validates the piece's ownership and authenticity. It's a form of digital asset that can be used to represent real-world artefacts like art, music, video, and in-game stuff Non-fungible tokens or NFTs are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other. Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can be used as a medium for commercial transactions.
