A non-fungible token (NFT) is a special type of cryptographic token that represents something unique. Non-fungible tokens are not interchangeable, so they are unique and identifiable. This contrasts with cryptocurrencies such as bitcoin and many “utility token” that are fungible by nature.

NFT is used to verify verifiable digital scarcity, as well as digital ownership and interoperability of assets across multiple platforms. They are used in several specific applications that require unique digital elements such as art, music, video games, or in the context of tokenized real estate for example.
