n3xB - Decentralized Bitcoin/fiat exchange protocol on Nostr

Last year I posted about the n3xB project - a proposal for an open protocol to facilitate Bitcoin exchanging across a globally shared order book, hosted using Nostr.
A year later today, I got the idea a lot more fleshed out - including a Rust library implementing the protocol, along with a demo iOS/macOS application and demo videos showcasing how this can work.
Hoping to get more interest and feedback on the idea. The hope is to make this an open standard for the decentralized exchanging of Bitcoin, similar to how Nostr itself is an open standard for decentralized social media applications.

I don't understand why we need to trade BTC for Fatcrab (FC)? the video didn't show the process when someone make deposit and withdraw their money, that's why I ask how do people convert the Fatcrab to fiat.

Let's say that I'm a Japanese and use JPY, is it possible for me to use JPY even no one use JPY? because it's really hard to find someone who use the same currency. I was thinking like a decentralized exchange that the user from any country can trade without need to use the same fiat currency.

AFAIK there's no popular decentralized Bitcoin exchange built on Nostr yet, so good luck to be the first one.
