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. ⚡

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 @nprofile…dnyq 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!

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

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.

Seed phrase challenges are a smart teaching tool. When your audience is ready for the next level, multisig plus time-delay security removes single points of failure. Worth a look: https://primal.net/bitvault

That separation you describe — identity vs signing authority — is the core design problem BitVault solves with multisig and time-delay. Different keys, different roles. Worth a look: https://primal.net/bitvault

2026-04-23 15:51:40 CEST

Bitcoin doesn't forgive mistakes. That's the premise.
Which means design decisions upstream matter more than in traditional systems.
Non-hardened derivation introduces relationships that can be useful — but also exploitable depending on context.
Understanding this is part of growing from user to operator.

Great to see you are also building in the bitcoin security space!
Maybe there's room for collaboration?

Q-Day timelines like 2029 are sobering. Most wallet designs won't adapt fast enough. Multisig + time-delay at least buys you optionality to migrate keys before exposure. Worth a look: https://primal.net/bitvault

Seed phrase come documento di proprietà: esatto. Il rischio vero è nella custodia, non nella generazione. BitVault usa multisig e time-delay per aggiungere livelli senza togliere sovranità. Dai un'occhiata: https://primal.net/bitvault

Zero-knowledge coordination with no backend is a real unlock for multisig UX. We've been working on the time-delay and key-management side of the same problem with BitVault — curious to hear your thoughts: https://primal.net/bitvault

Once you internalize the UTXO model, Bitcoin stops looking like a bank account system and starts looking like a distributed ledger of spendable outputs.

One subtle thing that confuses many Bitcoin users: balances don’t exist on-chain.
Bitcoin tracks UTXOs.
Wallets simply collect outputs controlled by your keys and display their sum as a “balance”.

Your mnemonic isn’t “a backup.” It’s a deterministic key generator encoded as words.
Entropy → seed → derivation path → address.
If you don’t understand that chain, you don’t understand custody.
