One of the best things about Bitcoin is that the deeper you look, the less it feels like magic. It becomes a system of small, specific mechanisms doing limited things very well. Hashing is a perfect example. SHA-256 and RIPEMD-160 are not 'advanced features'. They are basic building blocks. But the way Bitcoin uses them matters: proof-of-work, block integrity, transaction identifiers, public-key hashing, address construction. The important lesson is not just what each function does. The important lesson is that Bitcoin security comes from careful composition. Simple tools. Clear rules. Verifiable outcomes. That mindset is also central to how we think about self-custody security at BitVault. Security should not depend on vague trust. It should depend on mechanisms that can be understood, verified, and tested.

Some days ago our @Riccardo Biffi took the stage at #bcc8333 to talk about our approach to a trustless keys recovery system. Give it a look at www.b-ssl.com. Thanks SatoshiPassion for the awesome pics!

Just wrapped up a few intense days at Bitcoin Ireland in Dublin.

Really good event. Good people. Good conversations.

Loïc Ruchat-Leuthard represented BitVault on stage talking about self custody, coercion resistance, and why Bitcoin security has to evolve beyond simple key protection.

Meanwhile the rest of us spent most of the conference doing what these events are really about:
meeting people, exchanging ideas, discussing failure models, operational risk, and how real-world Bitcoin usage changes the threat landscape entirely.

One thing became very clear during many conversations:

more and more people understand that Bitcoin security is not only a cryptography problem anymore.

It’s increasingly an architectural and human one.

Huge thanks to the organizers, to John Waldron, and to everyone who spent time with us during the event.

Dublin was special.

Spent the last days at @BitCare Forum talking with Bitcoiners, builders, and security-minded people.

One thing is becoming increasingly clear:

Bitcoin self custody cannot rely only on protecting keys.

Real-world coercion, operational mistakes, and irreversible actions fundamentally change the security model.

Good to see more people starting to think beyond traditional wallet assumptions.

Thanks to our team on the field @Dr Francesco Madonna , @Midimarcus and Mariluz and to the organizers of the event!

Excited to announce that BitVault will be speaking at BitcoinConferenceIreland. Our Co-Founder⁠ 🇮🇪 @ruchat_loic will talk about Bitcoin self-custody, coercion resistance, and why real-world security needs more than just protecting private keys. See you in Dublin 👀 #Bitcoin #SelfCustody

Today we build the booth.
Tomorrow we take the stage.
The BitVault team is at @BitCare Forum preparing demos, visuals, the talk, and final details. We’ll discuss self-custody, Bitcoin security, and protection against coercion and real-world attacks. Come meet us 👀and learn more!

One way to think about it:

Bitcoin removes trusted third parties.
But it also removes "privacy by default".

Everything is transparent unless you actively design against it.

Tools like zpubs are useful.
But they are also dangerous if misunderstood.

This is why security is not just cryptography. It's architecture + behavior + information exposure.

Our summer of vaults keeps going! 🚀

BitVault joined X-Founders.

Bitcoin transactions are final. No reversals. No second chances. That finality is the point — and it demands security built specifically for it.

We're building Bitcoin-native security architecture: real-world risk models, stronger self-custody, and infrastructure that takes irreversibility seriously.

X-Founders is a step forward in that work.
