That's not how encryption or secure encryption schemes work. You can't just use _any_ pubkey and think, you can now encrypt _anything_ with it and still pretend like it's secure. You just rolled your own crypto.

Do we support Google or Facebook SSO? Since you sound like you think we do. 

Please stop shilling cashu, I like cashu but you make it look bad, lol

Not immediately, no, because there's no user auth in cashu by design (original Chaum's constuction involved accounts). But both lnurl-auth and nostr auth should give SN a pubkey that the zapper can encrypt with and the only thing that SN ever sees is an encrypted DM.

Unfortunately, users who log in via Google or Facebook will miss all the nutzaps.

I'm open to it. I just don't know enough to say yes to the dress.

Has anyone wrote about these UX-related things in depth somewhere?

Yes, it's possible. And I'll be working on the fedimint version of this in a week or two. 

Btw I've been testing all the fedinint v0.2 release candidates and it just dropped a few days ago. Offer still open if you want to play with it more.

Do you know if cashu supports offline receives?

> It's custodial but SN is not the custodian and might even never learn who the custodian is.

If SN would be running a cashu mint, SN would be considered a custodian.

@calle, or am I getting something wrong here?

And SN would need to run a mint to accept cashu (deposits) and **mint** cashu (withdrawals), right?

@om, how do you imagine SN to use cashu? Is there some misunderstanding?

It's custodial but SN is not the custodian and might even never learn who the custodian is.

Privacy is indeed a problem if you want to report accurate zap amount, however it's all so vulnerable to Sybil attacks anyway that we have to assume it's never "accurate" accurate.

BCH's memo.cash is a demonstration of what would happen to Nostr if it required setting up a non-custodial crypto wallet to start. 


This freebie thinks that currently, Cashu is the opposite of what we want _right now_ since it's custodial _and_ private.

But what does this freebie know, I am just a freebie, we don't do much PoW...

[important] foreign asset control compliance

Nostr is in the same boat.
IMHO cashu (and later fedi) nutzaps are the way to go.
