Just finished the initial protocol draft for n3xB - a proposal for building a Bitcoin/Fiat exchange on top of Nostr. Think Bisq/RoboSats but an inter-operable protocol and a giant open order book through Nostr relays. This also means unlike Bisq, this will be very usable by mobile clients.
We need more highly usable decentralized on-ramp into Bitcoin now, more than ever. Any feedback and technical scrutiny appreciated!
