One thing stood out during Summer of Vaults 2026:

Bitcoiners care deeply about security.

From Brescia to Prague, Dublin, Barcelona and Switzerland, we had countless conversations about self-custody, coercion resistance, operational security, inheritance, multisig and real-world threats.

Some people loved our ideas.
Others challenged them.
Both were equally valuable.

Open-source Bitcoin is built through discussion, criticism and iteration.

Thanks to everyone who stopped by to share their thoughts.

We're taking those lessons back into the product.

Public Release coming soon. ⚡

Prague is peak signal. @BTC Prague → https://btcprague.com

SHA-256 gets most of the attention because of mining and proof-of-work.
RIPEMD-160 is less discussed, but it also plays an important role in Bitcoin address construction. That contrast is useful. Some parts of Bitcoin security are visible and dramatic.
Others are quiet and structural. Both matter.

This is why good Bitcoin education should avoid two extremes: oversimplifying the protocol into slogans, or making it feel unnecessarily obscure. Hashing is technical, but the core idea is approachable: take data, produce a fixed-size fingerprint, and make it practically impossible to reverse or fake.
From that simple idea, Bitcoin builds a lot. We wrote a short article to explain where SHA-256 and RIPEMD-160 fit in the protocol.

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!
