A sunny day talking Bitcoin, security and self-custody at Bitcoin Social Forum in Florence ☀️₿
We brought BitVault on stage and then spent the day at our booth answering questions, showing how it works and, even better, listening to feedback from people actually trying it.
That’s the part we love. Building in the open, talking to Bitcoiners and learning from real users. 🧡
Thanks to everyone who stopped by!

Your vault works. Until something stops working. What happens next?
At Noderunners Arnhem, our lead developer Riccardo Biffi will run an interactive B-SSL failure-mode workshop.
We’ll put a timelocked multisig vault under three kinds of pressure:
- service failure;
- compromised keys;
- poor network conditions.
The challenge is to predict the vault outcome first, then watch how the simulator changes the state over time.
The point is not to label everything “safe” or “broken.” Temporary unavailability, recoverability and exposure to theft are different states, and time matters.

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.
