NFTs were sold as "proof of ownership" of digital art. It's worth being precise about what they actually prove — because for creators, the gap matters.
What an NFT actually is
An NFT (non-fungible token) is a unique entry on a blockchain that typically points to a digital asset — often just a link to where the image lives. Owning the NFT means owning that token in your wallet. That's it.
What an NFT does not prove
- It doesn't transfer copyright. Buying or minting an NFT gives you no copyright in the underlying art unless a separate agreement says so. The creator keeps the copyright by default.
- It doesn't prove you created the art. Anyone can mint a token pointing to an image — including images they didn't make. Minting is not authorship.
- It doesn't even guarantee you "own the file." You own a token; the file itself often lives on a normal server or IPFS that the token merely references.
So "I minted it" is not the same as "I created it" or "I own the rights."
What actually proves authorship
If you're an artist, the thing you want to prove is that you created the original work, first. That comes from dated proof of the source file, not from a token. Before you mint or post, timestamp the original artwork — the layered source or full-resolution master. A blockchain timestamp records that your exact file existed on a date, independently verifiable, so you can show authorship even if someone else mints a copy.

Bottom line
An NFT can represent ownership of a token and support a market for digital collectibles. But for proving you made the art and hold the rights, you still need copyright and dated proof of creation. You can create that proof in minutes.
