The security of Bitcoin Core’s codebase is rightfully emphasized in discussions of the Bitcoin network’s resiliency. But Bitcoin Core’s code is not the only code executed when running Bitcoin Core... brink.dev/blog/2025/09/1…

My fellow Bitcoiners, we are absolutely winning. Dont believe the catastrophizing. Spam isn’t a mortal threat to Bitcoin. Luke Dashjr isn’t going to hard fork Bitcoin. Bitcoin development is winning. There are nearly 100,000 Bitcoin nodes on the network (source: Luke’s

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/germ…

The online safety act is a terrible idea and the UK should feel bad.

📣 Germany is close to reversing its principled opposition to mass surveillance & private message scanning, & backing the Chat Control bill. This could end private —& Signal—in the EU. Time is short and they're counting on obscurity: please let German politicians know how

Another great post from Pieter on the filters issue. This time on Delving in reply to Chris Guida.

Spin up your fuzzing engines! In approx 1.5h, Marco will walk us through new compact block testing code. bitcoincore.reviews/33300

God, people are actually attaching a partition between “device scans my texts for crime” and “device just monitors my behavior for crime”. There’s no partition. They’re the same damned technology.

Cash on the internet. No auto-updates.

The Bitcoin Core development process and distribution model actually makes it somewhat harder to fix security issues, compared to other serious software distributors. Take Google Chrome as an example. The CVE fixing happy path is to develop and review a fix in private, push that

You know what’s frustrating? When you’ve got the skills, the drive, and the ideas to make an impact, but the only thing stopping you is a border stamp. That’s the reality for so many brilliant Bitcoin developers across Africa and the Global South. They can write world‑class

Bitcoin Core v30 and libbitcoinkernel with The Charlatan | SLP696 ReproducibilityMatters joins me to discuss Bitcoin Core v30 - removal of the legacy wallet, the Great Consensus Cleanup, the Bitcoin Kernel project & why healthy competition matters for Bitcoin’s future. (00:00) - Intro

“BIP 444”: - Most invasive protocol change ever proposed - Moti/Rationale consists almost entirely of FUD - Predictably controversial - Inactive BIP Editor with personal involvement “assigns a number” within hours on X (🙃), because “it might activate before he gets home”

It is wildly clear that Luke Dashjr holding any kind of elevated privileges is completely untenable. He's harmful. Resign.

The EU Council appear ready to approve Chat Control. This must be stopped. To highlight the corruption behind the proposal, Mullvad VPN now present "And Then?" The backstory: mullvad.net/blog/mullvad-v…

As part of Brink's mission to ensure the safety and robustness of the open-source Bitcoin Core software, we recently sponsored an independent security audit of the Bitcoin Core codebase. This represents the first public, third-party audit of Bitcoin Core. brink.dev/blog/2025/11/1…

People underestimate how insanely much work gloria (and instagibbs and a few others) have put into substantially restructuring the way Bitcoin Core relays transactions so that protocols like Lightning, Ark, and Spark can be radically simpler. We owe them immense gratitude.
