A hash doesn't really solve the core of the rug pull problem. If the hash doesn't match you know the file at that URL changed, but how was it changed? Was it just a metadata that didn't really change the artwork, or is it a totally different file?
And what does it mean for the transaction on the block chain if both the URL and the hash no longer match? Is it worthless now and unsellable? Or do you sell it with a note that says ignore the URL, ignore the hash, or both?
I did point out other issues and that may have been unnecessary, but a hash doesn't solve the rug pull problem if the art isn't part of the encrypted and (mostly) immutable transaction block.
