Mobile clients are limited in how much PoW they can mine.
No simple solution yet for them to delegate PoW to 3rd party.
I'm working on a solution for that. Tentative spec: https://oak-node.net/file?name=doc/ons/ons-2.md&ci=trunk

Makes sense. Will give it a read 👍👍
nostr:npub1ktw5qzt7f5ztrft0kwm9lsw34tef9xknplvy936ddzuepp6yf9dsjrmrvj worked on something similar back in the day but it never made much sense to me.
If a user needs to pay a PoW provider, why not just pay the relay to accept the note instead? This way the relay receives the revenue for actually storing and serving the note and nobody has to deal with another 3rd party.
