Maybe a use case for NFTs hah.

  It's a use case for merkle trees. Since the mere existence of the hash at a reasonably well-attested time is sufficient, you don't need the rest. A handful of central roots of various trees is fine, morally equivalent to announcing things with an ad in the newspaper.

    Now that I think about it, it seems to be a great idea - a verifiable record that some digital artifacts have existed at certain times. Of course it wouldn't be able to "prove ownership" or "prove being original" or other stupid ideas tokenbros throw around, that's impossible. But it wouldn't be profitable for the tokenbros and actually all the distributed attribute is not a requirement. We can probably set up a centralised append only DB which will periodically publish it's own hashes to attest that it wasn't tampered. Probably a useful tool for our deep fake future, the only question is how to scale it, who can be trusted and relied upon to input hashes in the system.

      The idea predates bitcoin IIRC.
