*Premise*: Nostr relays will eventually want to charge money for encrypted notes (because they can’t monetize on the data if it is encrypted).

*Problem*: If your encrypted notes use throwaway keys (to hide metadata), relays won’t want to handle it unless you pay for the encrypted notes. So to send metadata-blind encrypted messages, you need to dox yourself to relays to prove you paid to send the messages.

*Solution*: Unsure. How does SimpleX chat pay to support their networks? They will eventually have you dox some device ID to pay for premium? Unclear. How does Signal support their network? Unclear.
