What I'm proposing is almost already fundamentally here. For example, nostr:npub16c0nh3dnadzqpm76uctf5hqhe2lny344zsmpm6feee9p5rdxaa9q586nvr Primal already issues a primal.net lnaddress for everyone who uses the wallet. Now, all they have to do is use that same address as a NIP-05 too. Let the user pick their username at time of sign up, and that's all the user really knows about the key pair as it is only mentioned in passing to save nsec, placing the emphasis on the NIP-05 Nostr address. That's what they'd share to people and what others could use to find them. A more friendly UI/UX approach imo.

They require you to give a real name, email, and Telephone number.....I thought Coiners want anonymity?
When I tried the Primal app I used all fake details 😂 Fuck any kind of KYC.
