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. ⚡ Read more: Summer of Vaults 2026 Recap: 👇️

Building BitVault in the Open: Reflections from Summer of Vaults 2026 -

Over the past two months, the BitVault team has spent more time on trains, planes, conference stages, and event halls than behind our desks.

The biggest, most influential bitcoin event in Europe ever, again!

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. Check it out:

SHA-256 and RIPEMD-160: the Role of Hashing in the Bitcoin Protocol -

By mordom

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. Check this out to learn more about this topic: 👇

Some days ago our @npub1jq9n...ahqj 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!

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. More here →

From a zpub to your private key: the hidden risk most people miss -

Most people misunderstand “stuck transactions”.

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

Bitcoin Doesn’t Have Balances. It Has UTXOs. -

By mordom

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”. Learn more 👉️

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. Full breakdown:
