Non-Fungible Tokens (NFTs)
An NFT is a blockchain token that is one-of-a-kind, used to represent ownership of a specific digital or physical item.
In depth
"Fungible" means interchangeable — one USDT equals any other. An NFT has a unique ID, so it can stand for a particular artwork, ticket, game item or property deed. The token proves who owns it; the item itself usually lives elsewhere and is referenced by the token’s metadata.
Why it matters
NFTs generalise blockchain ownership beyond money — the same idea underlies tokenised real-world assets.
