Updated it to run Core v30.1 today sir! Sorry for the downtime…
JoinMarket NG
Announcing today a full rewrite of all JoinMarket components in modern Python. Focusing on performance, maintainability, and extensibility. While maintaining compatibility with the existing JoinMarket network.
https://github.com/m0wer/joinmarket-ng
Why JoinMarket? Has no central coordinator: most censorship resistant and peer to peer.
Why a rewrite? The reference implementation has served the community well for years, and we're deeply grateful for all that the contributors have done. However, the project is no longer actively developed (181 open issues and 41 open pull requests) and had architectural limitations such as relying on Bitcoin Core's BerkeleyDB wallets (deprecated since v26.0.).
New features:
- Support for light clients using Neutrino
- Rate limiting to prevent logs flooding
- Extensive protocol and implementation documentation
- Realistic E2E tests including reference implementation makers and takers
Future plans:
- Nostr relay integration
- Lightning Network integration (CoinJoinXT) to hide roles and eliminate fee traces
- A lot more ideas
Help wanted:
- Funding: Applied to HRF Bitcoin Dev Fund and soon to OpenSats. Other grant ideas or direct donations welcome.
- Security: Need sponsorship or a volunteer for external security audit.
- Contributors: Peer review, testing, documentation.
Entrypoint for migrating makers: https://github.com/m0wer/joinmarket-ng/tree/master/maker#migrating-from-joinmarket-reference-implementation
The reference JoinMarket served us well for a decade. Let's make sure the protocol thrives for the next one.
Awesome, I’ve switched to https://coinjoin.nl for privacy with my friends 🕶️
The boosts are a total scam by the way, first they rate limit popular video’s reach and squeeze you for money to increase the rate limit on it.
They make it sound like a porn movie in the disapproval 🙃
⚡️Former Mossad agent says that Israel uses false flag missile attacks from inside Gaza to help them "erase" Gaza.
They send missiles from Gaza towards Israel so they can portray Israel bombing Gaza as a response. https://x.com/i/status/2005807232999444536

I’m just writing tutorials on how to coordinate coinjoins this week 🕶️ hope you still like those 😇
Sponsorblock is great!
It has a copy of The Bitcoin Standard too ⚡

Merry Xmas 🕶️ thanks for all the rounds with https://coinjoin.nl this year!
May we stay as private in 2026.
Yeah, quantum is not an imminent risk yet. But there is a small chance that IBM's marketing team is not lying and that is why we should start thinking about what to do in 10 years when it does turn out to be possible to build a coherent 200000+ qbit quantum computer.
It's https://coinjoin.nl Sunday again frens! 
Hanging on, liquidation at 75k
I was long at 99k pls send help 🥲
My glimmer was walking hand in hand with my girlfriend today 🧡
We'll need to block the bad actors on a relay level.

Much better 🫡

What I want to see is a small UI change where users can easily set the coordinator again, not this warning that coinjoin has been discontinued...

The blue light (rayleigh scattering) of the sky is a foreground object to the moon, where it is a background for the pingpong ball. The sun acts as nearly a point source as light for the moon, where the reflections of sunlight from the surface also illuminate the pingpong ball. This gives the pingpong ball a noticable different lighting over the blue light background of Earth's atmosphere.
People always ask me how I came up with the idea for nostr:nprofile1qyt8wumn8ghj7un9d3shjtnswf5k6ctv9ehx2aqqypnyupc0uf08dhwwlf2f98qdushv45ypqzf4ql3ymerzyp63ekm65u5nzvk, so here's the story:

Did a testnet release candidate check for v30rc1, did not find any crashes or misbehaviour.
Yeah, that’s the point of shitposting on social media 😎

Hey Nostr fam 🫶 I’m new here, so allow me to introduce myself! My name is Elizabeth and I’m a wildlife biologist who just moved from Canada to the US 🇺🇸I’ve been a Bitcoiner for over a year and I had the pleasure of volunteering at BTC conferences in Nashville and Las Vegas and plan to go to El Salvador this winter! I’m excited to share some vlogs, content and learn more about Bitcoin while growing this decentralized community.
