And imagine doing something that you know will net you no profit, no status, no fame. That’s what an pseudonymous open source developer like Satoshi was like.

Want to. But my @npub1dll…0tz5 is still syncing, for 3 hours now. Last started just 3 weeks ago.
We need much better P2P solutions to have a chance of de-coupling ourselves from centralized exchange chokepoints.

2024-08-03 18:30:21

- reply

Not asking for myself. But how could Satoshi himself have gotten any open source development support? Or an anonymous team doing for example, coinjoin/mixing, etc? We need an ecosystem that can support anonymous developers without them running away with it.

What if I propose to use the Nostr network to bootstrap a global decentralized P2P order book to exchange between fiat & Bitcoin? To no longer serve as a backup to centralized social media, but also as the defacto, natively decentralized and non-custodial way to onboard people to Bitcoin? Ensuring the on-ramp & off-ramps can never be closed, at least until the entire world is using Bitcoin natively in every single transactions.

2024-08-02 23:28:33

- reply

Until all transactions in the world are conducted natively with Bitcoin, decentralized P2P is the best we’ve got. Native Bitcoin adoption will require price stability, and we are easily a decade away from widespread Bitcoin adoption at the mom and pop merchant level.
Platforms like Vexl is good. But they are like Blue Skys and Mastodon before Nostr. We need an open protocol for decentralized exchange. Not a lot of inter-incompatible little silos of centralized P2P solutions.
In particular, Vexl’s starting screen asking for my phone number tho, is not a good sign whatsoever…

Monero has its utilities, mostly as a stop gap for privacy transactions. But it has little chance to become the world’s store of value, medium of exchange, adefacto of account. To do so it requires a market cap and liquidity large enough such that there’s small enough volatility to be half of all of the world’s transactions. Its simply not happening.
Monero is the short time preference version of Bitcoin where it cannot wait for price stability and privacies properties to emerge. These properties are slow to emerge on Bitcoin because of the need to be a ‘sly and roundtable way to introduce something they can’t stop’. In fact, Monero is effectively slowed, if not already stopped, because its simply not sly enough. Monero is the idealistic but impossible perfect that is in the way of the practical and already working good that is Bitcoin.
Medium of exchange and privacy properties will continue to improve on Bitcoin, at a rate that will not overly alarm, and effectively penetrate the authoritarians. Only Bitcoin has a chance to truly separate money from the state and become the one defacto money for humanity.

Liquidity and UX are very poor unfortunately. They are like the Mastodons of P2P before Nostr existed.

2024-07-29 06:44:41

- reply

Absolutely. But you can also always find a different counterparty if its a decentralized P2P platform.

2024-07-29 06:42:48

- reply

I am not sure how Monero fixed bridging the global economy, which the majority still sell product and services only for fiat, into anything.
Not to mention those who held onto Monero instead of Bitcoin, has diminished in purchasing power relative terms.
Both can exist at the same time. People are free to choose. But P2P solution is currently sorely inadequate nevertheless

Just like you are not using centralized services for your social media. Don’t use centralized services for your Bitcoin. Then you’ll never be chain analyzed. Pay with Bitcoin. Or use P2P exchanges. Make P2P exchanges the standard

2024-07-24 00:31:25

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.

Skimmed this also. I don’t agree with the take re: AI. But lets not get distracted from building a open protocol for a shared Bitcoin/fiat order book on Nostr~

Yes sir. Some update to BUIDL on n3xB.
First implementation of the n3xB protocol library completed, written in Rust.
Also an example implementation & app built on top of n3xB as a demo.

For the next cyberpunk evolution, what if I propose that Nostr can be the trojan horse for building a network of P2P fiat on/off ramps? Think an open protocol for Bisq that can also be mobile friendly. Instead of building monolithically, (a Bisq stack & its own order book, a Robosat stack & its own order book, etc), a shared liquidity pool can be formed so that any new trading application can be additive to the liquidity of the shared global order-book, instead of fracturing it?
I have written the first working version of the n3xB protocol library, along with a fun demo implementation. Looking for feedback, and the special people/teams that will build the Damus to n3xB. Someday becoming the challenger to the Binances of the world, like how Nostr is growing to be a viable challenger to Twitter, etc.

Just created a video overview of the Fatcrab demonstration project. Its mean to demonstrate how the n3xB Bitcoin exchange protocol library can be used to create a mobile friendly decentralized fiat on/off ramp around a Nostr based global order book. More collaterals (including the macOS demo app itself) to come over the coming days

It’s admittedly a lot more work than I expected. I’ve done first draft of the base protocol. And built an example trade layer, along with an iOS app on top for demonstration. Stuck at getting Apple Developer license. It’s close to a full KYC process over there and I don’t want to get doxxed….
Worst case I’ll post about what I worked on so far with a much inferior Mac only version of the demo app. The work can be see on GitHub real time tho.
Ultimately the hope is others build their own intercompatible projects on top of n3xB, or to port existing solutions on top to be intercompatible, instead of me building yet another exchange verticals app besides what’s already out there (Bisq / RoboSat / Mostro etc)

I have been working on something similar, but feel like we should collaborate instead of compete. I have no interest in carving another solution out when there’s Bisq and Mostro and RoboSats, etc. Check your DM to further discuss. Thanks!

2023-04-19 08:15:48

Just shared my super naive playground of using Nostr for some of the offer discovery and trade initiation flows onto Github. The purpose is just to derisk, and not meant to reflect too much on the actual implementation for the initial PoC. Still working on my other playground that tries to construct a multi-sig across multiple BDK powered wallets.
Will update the proposals once again with all my learnings once both of these are complete.

2023-04-19 06:55:57

It seems Nostr based P2P marketplace is all the rage these days. And people are viewing it as if these are competing solutions.
My intention has always been to create a single open order-book on Nostr that no one owns. There is literally no money to be made in this. And I’m doing this anon so even repuation and glory upside is highly limited. The only reason to do this is to create ways for on-off/ramp into and out of Bitcoin. My stack gaining purchasing power is more than enough motivation for me.
When I started nobody was talking about this. Now it seems to be all the rage. I am more than happy to drop n3xB completely if someone already got this vision built.
The competition should not be at the protocol/order-book level. The competition should be competing clients, liquidity providers and arbitrators - NOT competing order books and protocols. If it’s the latter then we already have it in the form of Bisq and RoboSats, and would be zero reason to put this on Nostr. The only reason to put this on Nostr is to have an inter-operable, highly liquidity order-book, instead of having wall gardened orderbooks, albeit P2P, etc that we already got today.
If anybody is building ‘competing protocols’ that is also meant to be an interoperable order-book, we should talk. One of us should drop. I’m more than happy not building protocols and build mobile clients and UX instead. DM me.

Custodial solution is how one’d kill LN and attack Bitcoin. For all we know Wallet of Satoshi is a FinCEN project

Not much we can do about BSA except for creating an unstoppable alternative.
Custodial centralized entities created weak points to be attacked and make the alternative less unstoppable.
Custodial solutions weakens the alternative and helps the BSA continue its existence

Not a fan of custodial solutions anyways. Its a lose-lose situation

2023-03-21 02:23:27

It seems to me you were saying that you don’t believe Bitcoin to be able to replace all forms of currencies. I’d assume also means that tools which goes towards this end, including to fight state national currencies as all forms of money, will be deprioritized from the road map.
Again, I hope I am wrong. But I am afraid, it is indeed not up to public companies to take on such positions. And if so, I can understand, even tho still being disappointed at the same time.
Why us pseudonymous FOSS projects exists.

More important than to prognosticate what the end state might look like - its to create the future we want to see. I do question the conviction of Block towards Bitcoin if the CEO of one of its division does not believe in a Bitcoin future. Perhaps the limitations of a state regulated public company? I hope I am reading this wrong here.

I am sure more devs will be arrested as the fight goes on, at least a few to create a chilling effect. Kudos to those not doing so anon/nym. But at the same time if there are any trusted roles (Github admins, etc), I’d want to make sure they have gained reputation on their nym, not their real life ID, as they are only one gun point away from rug pulling all of us.

Yes. The problem is to get a valid LNURL/Lightning Address with a working web server on the other end of it.

2023-03-14 19:54:24

I don’t see the ability to generate a LNURL on Zeus. Let alone if its NIP-57 supporting. As it is your Nostr profile doesn’t have a LNURL address to Zap to.

I cannot find any info from 30 seconds of Brave Search that indicates this setup will generate LNURL with NIP-57. And not certain whether my browser needs to be always on to service LNURL requests.

2023-03-14 18:59:41

- reply

Took a quick read of LNC, but seems like it connects your browser to your node. So at the least your browser needs to be always on and act as a web server or something then?
Most plebs would have already downloaded Wallet of Satoshi by now.

To receive Zaps?

2023-03-14 18:36:58

Hot Take: I am officially against #LNURL and #Zaps, at least the way it’s been rolled out. #Nostr Zaps basically pushed everyone to @Wallet of Satoshi which is custodial and hugely centralizing to LN. I have a RaspPi and still, there’s no easy way to take LNURL and Zaps. Even with a VPS it’s non-trivial to get non-custodial LNURL+Zaps going.
Look, you all can ‘have fun’ on Nostr (Parker Lewis on TFTC described as wasting time). But when you are harming #Bitcoin then you have lost the plot.
If you LARP around then you will find out what a CBDC world looks like.

2023-03-14 15:42:32

Hi! I am trying to build 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!

It sounds cool and all. But really only possible because a lot of devs doing above FAANG level quality work, *For Free*. Incentivizing devs, or really just make sure they can pay rent, and still work on the open protocol… is always the Achilles’ heel of open protocols. Including Bitcoin itself.
