ERC-721
An Ethereum token standard for individually identified non-fungible tokens.
In more detail
ERC-721 gives each token an ID within its contract, making it possible to track a particular NFT's owner and transfers. The standard handles that onchain identity; it doesn't itself grant copyright, keep an image online forever or establish that a collection is official. Those questions need separate evidence.
How you might use it
Your wallet owns token #42 in a collection’s ERC-721 contract, while the artwork and any usage rights are described elsewhere.
