tokensnofungibles

When you buy an NFT, you don’t buy the image.

You’re buying a record that says who owns that image. That’s it. The file almost never lives inside the chain; it’s too heavy. The token stores a link that points to it, stored on another server. If that server goes down, the token is still there. The image, not so much.

And here comes the same old mistake: thinking that “unique” is the same as “valuable.” It isn’t. Imagine someone mints the same photo ten times. Each copy has its own token number. That’s ten unique records, but the photo is identical in all ten. Uniqueness is set by the code. The price is set by someone else.

That—the record that distinguishes one piece from all the others—is what’s known as a non-fungible token, or NFT.

On Ethereum, most follow the ERC-721 standard: each piece has its own identifier, and you can’t swap one for another as easily as you can with $ETH .

KEY CONCEPTS

- An NFT is not the file: almost always, it’s a link pointing to a file stored off-chain.
- “Unique” is not synonymous with “valuable.” Uniqueness is guaranteed by the contract; the price is decided by demand.
- An NFT is not the same as a governance or utility token: those give voting power or access, but they don’t prove ownership of a piece.
- Not every NFT collection is 100% non-reproducible. Standards like ERC-1155 mix unique pieces with repeatable ones in the same contract.

It’s like having the certificate for a painting without the painting: the paper is real, but the artwork is still hanging on another wall.
