# Non-Fungible Token (NFT)

An NFT is a unique cryptographic token that records ownership of a specific digital or physical asset. Cryptocurrencies are fungible. One Bitcoin equals another Bitcoin. NFTs are not. Each token has a unique identifier. You can prove who owns it, that ownership moved from one address to another, and when that transfer happened.

Uses include digital art, collectibles, game items, domain names, credentials, property rights, and concert tickets. Any asset that needs provable, transferable ownership can sit in this format. The mechanism is a smart contract that tracks owners. Most follow a standard such as ERC-721, which defines how transfers work and how metadata is stored. An NFT that points at a digital image does not stop anyone from copying the pixels. It proves who owns the original token. For art, that creates scarcity and attribution. For collectibles, the community around the asset is often the point. Some NFTs have clear use: deeds on a chain, in-game items with utility, credentials an employer will check. Many others are pure speculation. The applications are broad. Gaming assets. The technology is straightforward. Debate centers on what value NFTs have and why. An NFT pointing to a digital image doesn't prevent someone from copying the image. Ethereum's NFT page explains a unique token whose metadata points at an image, pass, or deed. ERC-721 is the common standard.
