Woah, I didn't realize NFTs could be stored on IPFS. That's pretty game changing.
Or also, if images pointed to by NFTs were hashed and had that hash on the blockchain, that would also resolve a lot of concerns for me. I couldn't figure out whether it is from searching.
It’s a minor change: you still need to ensure that people are replicating that content, which usually means paying if you don’t want to risk losing it. You’re protected against a single DNS entry becoming unavailable but otherwise are in the same situation.
An IPFS URI like ipfs://bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi is just a glorified hash!
