By mordom A Bitcoin address is not a public key. For most users, an address looks like a random string. Something you copy, paste, and use to receive funds. But behind those characters lies a very precise chain of cryptographic transformations. Nothing is arbitrary. Each step exists for a specific reason: security, compactness, resilience, and long-term…
BitVault has joined the X-Founders accelerator to continue building Bitcoin-native security systems designed for real-world risk, irreversible transactions, and stronger self-custody. For us, this is a meaningful step: a focused environment where we can keep refining our product, testing our assumptions, and working alongside founders and operators who understand the seriousness of building security for…
By mordom Imagine a normal situation. You have a hardware wallet. You want to monitor activity without plugging it in every time. Or you need to share addresses with your accountant. Or you’re using a watch-only app.So you export a zpub (an extended public key) and share it. The assumption is simple: “I’m only sharing public…
Where to meet BitVault next 🌍 Bitcoin lives in code, but it grows through people.In the coming weeks, we’ll be out there meeting the community, speaking on stage, and having real conversations about security, self-custody, and what actually happens when things go wrong. If you’re attending any of these events, come find us. We’d genuinely…
By mordom Your wallet does NOT generate infinite addresses You send a transaction. The wallet says “sent.”Then you wait.After an hour it’s still unconfirmed. After a few hours you start to worry.The exchange doesn’t credit, the payment doesn’t arrive, the recipient messages you.At that point, it feels like there’s nothing you can do. In reality, you…

By mordom Open your wallet and you see a number.0.42 BTC.1.8 BTC.0.003 BTC. It looks like a bank account. A single balance that belongs to you.But that number does not exist on the blockchain. Bitcoin does not track accounts or balances per address. There is no global registry that says “this address owns X”. What…
Bitcoin is trading around $65K and has just printed a death cross on the 3-day timeframe. This is not a short-term signal. It reflects a loss of sustained momentum and a shift in broader market conditions. What changed The sequence matters more than the signal itself: This suggests the market tried to stabilize and failed,…
By mordom Anyone who owns Bitcoin is familiar with the 12 or 24 words.We call them a “seed phrase”.But they are not the seed. And this is where one of the most common misunderstandings begins: many people confuse the mnemonic (BIP39) with the actual cryptographic seed. The words are a human-readable representation of the original…
By mordom In the process of creating a Bitcoin wallet, everything depends on a single initial value: entropy. If that entropy is unpredictable, the wallet is secure. If it’s not, no hardware wallet, multisig, or backup can fix it.In Bitcoin, a private key is an integer k such that: 1 ≤ k < n (see…
