One way would be to store a hash of the content at that URL with the NFT, but there's actually a better way. IPFS supports the concept of immutability [1], so you could just use an IPFS URL with a content identifier. It also allows for revisions linked to the original content identifier.

- neilalexander 5y agoWhile this coincidentally works for IPFS CIDs, it's not clear why hashes wouldn't be first-class fields in the NFT itself.
- jordemort 5y agoIs it correct that things can disappear from IPFS, if nobody is continuing to bother to pin the content? It seems like you could get an immutable URL this way, but that there's still no guarantee that the URL will remain accessible.
- neilalexander 5y agoYes, that is correct. The IPFS nodes with the relevant content may go offline, people who are pinning the content may just decide to not pin it anymore for whatever reason and then eventually the content would just disappear from people's caches.
