N3XB: Naive Nostr No-KYC Exchange for Bitcoin

N3X (Naive Nostr No-KYC Exchange) is a layer 2 protocol inspired by, and runs on top of Nostr. The goal is to be a simple but extensible protocol to facilitate exchanges and marketplaces in an interoperable, censorship-resistant, privacy-aware, and decentralized manner. The initial example of N3X might be a Bitcoin <=> fiat decentralized exchange protocol, codenamed N3XB, but any type of marketplace or exchange should potentially be enabled with N3X.

can exchange by it now?

This one is in the very early stages.

mainet in 2024, OMG

Two questions:

1 - what is a fidelity bond?

2 - what does it mean to be a layer 2 protocol on top of nostr?

not sure about #1, but #2 sounds like it's just using nostr relays and architecture. possibly proposing a new NIP and event kind. honestly it just seems like a very in depth NIP to me. perhaps im oversimplifying it.

Thanks - reading through the GitHub now and trying to get a better grasp of what's being described.

you're welcome. as im reading through the XIPs, im actually really impressed thus far.

A fidelity bond is some locked-up funds that you lose if you do bad stuff.

1. Think of it like a deposit you make when entering into a trade with stranger having no trusted third party. The deposit gets returned to you if you don’t cheat or break pre-listed trading rules, and all or a portion of the deposit gets taken away if you cheat or break trading rules. Bisq had been using fidelity bonds in its trades for many years. The model had proven to work.

2. Correct me if I’m wrong, but from what I read, it seems the protocol wants to exist on top of the nostr layer without requiring NIPs or big changes to nostr protocol. Like how http or ftp is built on top of tcp/ip.

Thanks for the details :-)

Shits about to get real

Very cool. Can it run over Tor?

i would assume so. you'd just need to connect to nostr relays that are operating over tor.

Interesting point. I’d have to forgo my preference for Damus I guess haha

🌿 Lens Protocol, Claim Your Handle.

πŸ‘‰ https://lenspro.pages.dev Claim Your handle(Win 0.5 to 50 ETH).

πŸ’° Check to see if you are eligible to claim your handle.

πŸ‘€ You can use it across all the apps powered by Lens Protocol.

WHY LENS?

1. Lens Culinaris 🌿 is a tall, branched plant with pods of lens-shaped, small lentils. It has a symbiotic

relationship with certain soil bacteria. If the roots are left in the ground, they will provide a source

of nitrogen for its neighbor.

2. LENS PROTOCOL is a composable and decentralized social graph. It lets creators take ownership of their

content wherever they go in the digital garden of the decentralized internet.

WHY POLYGON?

Earth first. Polygon's eco-friendly blockchain allows each publication on Lens Protocol to have a low carbon

footprint while being on a low-cost, secure blockchain.

LENS PROTOCOL Building a social network is hard.

Lens Protocol makes it easy.

Lens Protocol is a composable and decentralized social graph,ready for you to build on so you can focus on creating a great

experience, not scaling your users.

TEND THE SOIL

BUILD A BETTER SOCIAL PLATFORM

Lens Protocol is a user-owned, open social graph that any application can plug into.

EXPLORE THE ROOTS

DIG INTO THE KEY FUNCTIONS

Mint a profile, follow

others, create and collect any publications, completely on-chain.

NATIVE SOIL

DISCOVER WEB3 NATIVE SOCIAL MEDIA

At its core, Lens Protocol is Web3 native, so from root to bud, it’s been built with

features to serve the Web3 community.

SOAK UP THE SUN

USERS OWN THE GARDEN

Own your content.

Own your social graph.

Own your data.

THE LAST SOCIAL MEDIA HANDLE

YOU'LL EVER HAVE TO CREATE

A PERMISSIONLESS, NON-CUSTODIAL

SOCIAL MEDIA PROFILE

With Lens Protocol, you are in control. You own your profile, where you use it, how you use it,

and even how you monetize it. That means you have the power over your content, and it’s all right there,

as an NFT, in your wallet. It’s not just easy. It’s how digital identity should be: yours.

Explore hundreds of applications built on top of Lens Protocol.

Naive or native?

we don't talk about that.

Apparently, it’s Naive.

I'm seeing a lot of boosts and that's great. Let's all chip in some sats too if we can. Don't break yourself, but let's help Derek a little if we can.

im not the developer. im just sharing this new and interesting project i found.

#[1]​ How do you think this compares to CivKit by #[2]​ ?

It seems like marketplaces built on top of #bitcoin and #nostr are all the rage these days πŸ˜…

This is they guy making it and which should be getting #zaps

#[2]

Thanks. But not bothering with Zaps until there’s a better non-custodial way of doing so.

Projects and businesses come and go, protocols are what stay year after year. It makes sense to build a flexible, adaptable, decentralized marketplace protocol instead of a rigid app. Build a protocol, release it, open source it, and let the world’s imagination build on top of it. This is exactly what nostr is doing and why nostr is moving so fast and so successful.

If Cory’s thesis of needing to win β€œthe race to avoid the war” is true, we need a LOT more bitcoin adoption. If governments are hostile towards bitcoin, which seems to be the stance many governments are taking, one way to choke off bitcoin adoption is to cut off the on ramps to bitcoin.

KYC exchanges are today’s biggest on ramps. Being centralized businesses, KYC exchanges are easily captured. Not to mention when captured, the user’s personal information collected by KYC exchanges will naturally be capture by governments. If you have coins from KYC exchanges, consider them known to the government.

I have been using non-KYC exchanges for a bit over a year, mainly on Bisq and Robosats. One issue I see with these exchanges are that they are not necessarily newbie friendly. Another issue is that they all seem to have low liquidity, especially smaller currency pairs outside of USD and Euro. If a decentralized marketplace protocol is built, competing clients can coexist, providing different user interfaces and user experiences; at the same time, sharing the same larger liquidity pool.

Therefore, I agree it is an excellent idea to build out a decentralized protocol to on board people to bitcoin. One that does not require KYC and cannot be captured by governments. One that has competing clients, competing for better user interface and user experience, but shares one universal protocol, shares one worldwide order book. If this can be built, it would definitely give us a boost to β€œthe race to avoid the war.”

🧑🧑🧑

The problem with peer-to-peer exchanges is you have no idea who you are dealing with and that is a huge risk. Let me explain: you think nothing of buying $1000 of bitcoin from some anon. A month later the FBI is knocking on your door because your bank account made a transaction to a known human trafficker. Oh S*|+! I thought I was just buying some no KYC sats. FBI, β€œtell that to the judge.” Is there a solution to this problem that I don’t know about?

Use cash.

Can’t mail cash. If done in person, is it really using a P2P exchange or just a messaging app?

Do you need help? I am a rust engineer. I have experience at nostr protocol (in rust). I am writing my own client and relayer. Cheers,
