>ERC-721 is the standard that dictates how one should create an NFT. Each ERC721 NFT must have a tokenURI field, that is an external link to a JSON file stored on an external server ... You can notice the image field, which is a link to an image.

Not just a link, a link to a link! And when that server goes down next year, all those JSON files will vanish.

I'd expect at least a hash of the image to be stored on the blockhain..

Wait, is this not how it works? Seemed like a safe assumption...

Even if it is, you can't really reconstitute the image from the SHA. I mean, unless we just created a new proof of waste algorithm.

No. The value in the thing is in the key that minted it. Think of it like a signed baseball: easy to replicate, but the original is worthwhile.

I'm very surprised that those (the JSON and the picture) are not stored in a decentralised way e.g. IPFS or Swarm.

So if I buy an expensive NFT, and the domain goes down, the NFT is now worthless?

We should be on the lookout for any of these domains expiring, then we will buy them and upload Rick Astley GIFs
