Cool side effect of using public key cryptography for notes and other stuff: I can write a note in the physical world with proof that I wrote it. Carve a message into drying cement and sign it with my private key. Eternal proof that I was there.

Do I misunderstand? Nostr is not blockchain. Your note can disappear if is not present on any relay. All that is guaranteed is the sender’s cryptographic identity.
