Non-Fungible Token (NFT)

An NFT is a unique cryptographic token representing ownership of a specific digital or physical asset. Unlike cryptocurrencies, which are fungible, one Bitcoin equals another Bitcoin, NFTs are distinct. Each NFT has a unique identifier. You can prove ownership of an NFT. You can prove that ownership transferred from one person to another. You can prove when the transfer happened.

The applications are broad. Digital art. Collectibles. Gaming assets. Domain names. Credentials. Property rights. Concert tickets. Any asset that benefits from provable, transferable ownership can be an NFT. The technology is straightforward. An NFT is a smart contract that tracks ownership. It typically follows a standard like ERC-721 that defines how ownership transfers and how data is stored.

Debate centers on what value NFTs have and why. An NFT pointing to a digital image doesn't prevent someone from copying the image. It just proves who owns the original copy. For digital art, this creates scarcity and verifiable attribution. For collectibles, it's about the community around the asset.

Actual valuable NFTs exist, property deeds on blockchain, gaming assets with real in-game utility, credentials that employers recognize. But many NFTs are pure speculation.
