idea: pay for PoW over nostr:
Send note to a paid pow relay where you register your pubkey. The contents of this is a json-encoded unsigned note that you want PoW on.
Service decodes this note, does PoW, sends it back to relays encrypted. Client sees this, decrypts, checks it against the original note sent (that is encoded in the response for convenience), signs it, and broadcasts.
You could use this for threads that have PoW restricted replies
The service could send you a lightning invoice in an encrypted DM if you're not registered. "Pay this invoice for 10 PoW notes". Pay invoice -> service starts working on sent notes. Maybe there could be a lightning invoice NIP where clients can integrate with lightning natively.
ive already standardized it:
Another idea. Insurance companies seem to offer some benefits if you have "fitness points" or whatever they are. Basically they're something gotten from fitness apps. Idk or care. Anyway: write a message draft that you want pow for. Then go jogging with smartwatch (that has a nostr integration), and when you've collected enough e.g. heart rate points, the message is proven. Going to get my pre-ordered repebble which could be hacked this way 🤷 Maybe heart rate points could too, but anyway...
