NFT stands for Non-Fungible Token — a unique digital asset recorded on a blockchain that proves ownership and authenticity of a specific item. Unlike cryptocurrencies (where each Bitcoin is identical and interchangeable), each NFT is one-of-a-kind or limited edition. The “non-fungible” property means it cannot be replaced by an identical copy — ownership is verifiable, transparent, and permanent on the blockchain.
NFTs can represent ownership of: digital artwork, music, videos, in-game items, virtual land, sports collectibles, domain names, event tickets, and real-world asset certificates. The majority of NFTs are built on the Ethereum blockchain using the ERC-721 standard, though Solana, Polygon, and other chains also host significant NFT ecosystems.
The NFT market experienced a massive speculative bubble in 2021–2022. Notable collections like CryptoPunks and Bored Ape Yacht Club (BAYC) sold individual NFTs for millions of dollars. The market subsequently collapsed 90%+ from peak values, highlighting the extreme speculation involved. However, NFT technology continues to develop with legitimate use cases in gaming (true digital ownership of in-game assets), ticketing, and digital identity.
Example: Artist Beeple sold an NFT of his digital collage “Everydays: The First 5000 Days” at Christie’s auction in March 2021 for $69.3 million — the third-highest price ever achieved by a living artist, entirely for a digital file with no physical component.
