I'm working on nostr authentication using schnorr signatures too
Discussion
Love it! This is the most obvious next step for browsers. I am not sure why it hasn't been pushed through by a big player. Probably because they are all oauth providers and the lock in is welcome.
Thanks! It's based on NIP-98 which I co-wrote with Kieran and is in wide use. Re big players, absolutely yes. They also want to couple everything to email. And the email providers are also the web giants.
This little shim will allow you to do an authenticated write operation, for example.
