I think there's something missing here. Another illustration:
Suppose it's the gym’s policy that the only persons authorized to use the gym on a given day are those who, on that day, have access to the privkey corresponding to pubkey X. Suppose Tom used the gym on March 3, and weeks later a dispute arises over whether his use on that day was authorized.
Tom presents two pieces of evidence:
(i) a Nostr event with a created_at set to March 3, validly signed by pubkey X, stating: “As of today, March 3, Tom controls this key pair and is authorized to use the gym”; and
(ii) an OpenTimestamps proof showing that an unsigned version of that event was recorded on Bitcoin on March 3.
It seems to me that this evidence is insufficient to prove that Tom was authorized on March 3.
