In Response to My first impressions of Web3

> A lot of NFTs do use Google Drive or Imgur or whatever. However, I can promise you that one of the first things people do when making sure they are not rugged (crypto-term for scammed) is to make sure it’s not possible for the author to suddenly delete or change the image.

I'm curious about this point; if the only thing stored on the chain is a URL (including Drive/Imgur) then there's no possible way to actually preclude the content from changing right?

It actually does seem very weird that people aren't at least putting a #sha1= in the NFT URL to be able to verifiably know if the underlying content did change.

When you use something like IPFS the url is created from a hash of the file contents, so it is not possible to change the file without creating a new url.

Sure if it's IPFS. The article seemed to suggest that there were NFTs that were just Imgur urls and that a savvy purchaser of that NFT would somehow ensure the Imgur image couldn't be deleted or changed, which I don't believe is possible.

I’ve seen all of the above.

I’ve inspected NFT contracts and saw they were designed wrong with a direct link to a website that could go down

And I still minted or bought them because the community or game was interesting

I’ve also seen extremely clever completely onchain nfts. I like those.

Indeed that would seem to be the point of the entire exercise!

seems simple enough right .. to add a ?h=HASH_OF_IMAGE in the URL .. maybe the real issue is that fact that the server pr the actual image itself can disappear ?
