A Non-Fungible Token (NFT) is a unit of data stored on a digital ledger — a blockchain — that certifies a digital asset to be unique and therefore not interchangeable. NFTs are commonly used to represent ownership of images, videos, audio, generative art, and other digital files, with provenance and transfer history recorded on-chain.
NFT use cases span profile-picture (PFP) collections used as identity markers, generative art projects such as Art Blocks, historical-firsts like CryptoPunks and MoonCats, music NFTs including the Consensys-funded EulerBeats project, and influencer-driven sold-out collections. The category gained mass cultural attention in 2021 and is connected to broader shifts in digital ownership, the 📝metaverse, and 📝Web3 infrastructure.
📝Scott Galloway has written extended commentary on NFT economics and the speculative dynamics of the category. The NFT ecosystem also encompasses marketplaces, glossaries, and adjacent communities — see the 📝NFT Glossary for term-level definitions, and 📝The Notecard System for how NFT-related entries are catalogued in this library.
