Subnostr

It’s a good point. The minimal spec was to use less data and since it relies on the AUTH NIP, we already know the pubkey.

I’d imagine someone could want someone else to request generation of POW for one of their events and then get them to sign it. But why have a middle man?

The assumption is the requestor holds the secret key for the pubkey of the events they are asking for POW generation for.

Secondly, since it’s expected this would never be a free service, the pubkey would be the member or account holder or account to be charged/deducted from.

Open to suggestions if pubkey is needed.

I think making these things modular would be ideal (i.e. it should be possible to do pow for people without even having read the auth nip). The way you have the nip now it kinda seems as though you need to run a relay just just to be a pow service provider.

Ok, so here is a draft NIP for a Proof of Work Service Provider. All Feedback welcome!

Would love to hear from relay operators, open source relay contributors, client apps, Nostr users.

Basically, it allows for you to generate an event POW before signing as part of a relay membership or pre-paid credit system. Ultimately to succeed, Nostr apps would need to offer it.

I have a fully functional rust implementation I’ll likely open source (if enough interest), that just needs the payment integration code - and a bunch of testing.

Proof of Work Service Provider for Nostr - provides a way for clients to request a target proof of work difficultly (for event id) for an event prior to publishing.

Next, hopefully we add support for some clients apps, so it can really be tested.

Draft NIP included in repo.

I’ll do some more testing today, however code is available now. Feedback/bug details welcome.

Suggestions for a lightning payment processor even more welcome.

In the nip, why not add the pubkey to the pre-hashed event?

An alternative to PoW is just to pay the relay a fee directly to accept their event. The downside here is that when you pay a relay, you then need to pay the next relay, and the next relay.. where as if the relays accept either payment or a minimum PoW, then you can generate PoW once and broadcast to all relays - which is more censorship resistant as well.

A relay that I believe does what you’re after is strfry. It should cover your needs today.

I think the combination will be ideal. How else would you discover new people to add to your WoT?
