The acronym NFTs refers to Non-Fungible-Tokens. NFTs represent unique assets with properties that are not replaceable. These tokens contrast with Fungible Tokens that can be easily interchanged with another equal or similar asset (e.g., a cryptocurrency).

NFTs became popularized with digital art projects like CryptoKitties (2017), CryptoPunks (2017), Bored Ape Yacht Club (2021), and the record-setting Beeple’s artwork Everydays (2021) that sold for 69 million dollars.
