Is there a way to prove the origin of an npub on #Nostr? #AskNostr

My initial thought would be to hash all the list of all npubs on a relay at a given time and post it on the #timechain using opentimestamps.org
I wonder if there’s a way to filter by age of npub? Unfortunately I think it’s possible to spoof/sign a note with a fake time so there’s need to be a way to verify.
