lol, another proposal right here on SN -

n3xB - naive Nostr no-KYC exchange for Bitcoin

Have no idea how the Nostr stuff will affect design, or even user experience, but it'll be interesting to watch how competing approaches fare, and produce better tools and services in the process.

The Shocknet team's Lightning.Pub is a good example - they don't like Bolt12, or at least, they don't like the onion messaging it uses, and openly state this as the reason for pursuing the Nostr based approach they're taking -

For them, Nostr is a solution to the problems they see with LN tooling presently -

I don't have the chops to credibly assess their claims, but appreciate the work being done will ultimately help push things forward.
