Security insights, MultiSig practice, and self-custody thinking from the Ownbit team.
Casa vs Ownbit for crypto inheritance: an honest comparison
Both use multisig so heirs never touch your seed phrase — then they part ways: Casa verifies death through a human process; Ownbit enforces a 416-day timer on-chain. Which trust model fits you.
Turn a spare phone into a cold wallet
The phone in your drawer can do what a hardware wallet does: keep keys on a device that never touches the internet, and sign transactions that cross the gap as QR codes. A practical setup guide.

Address poisoning: the scam that preys on copy-paste
Attackers seed your history with look-alike addresses and wait for one careless paste. In May 2024 a single mistake sent roughly $68M of WBTC to a poisoned address. How the scam works and how to kill it.

Google’s Willow chip and Bitcoin: how close is the quantum threat?
Willow demonstrated below-threshold error correction on 105 physical qubits — a real milestone that still leaves cryptographically relevant machines orders of magnitude away. A sober read.
Watch-only wallets, explained: see everything, sign nothing
A watch-only wallet holds addresses, not keys: it can show balances and build transactions but can never spend. Why that split is the backbone of every serious cold-storage setup.

One key can be lost AND one key can be stolen, and your coins survive both. Why the 2-of-3 threshold hits the balance point between security and survivability — and how to place the keys.
MPC vs MultiSig: an honest comparison
Both split signing power across parties; they do it in fundamentally different places — off-chain math vs on-chain script. Where each wins, where each breaks, and how to choose.
Exchange proof of reserves: what it proves — and what it doesn't
After FTX, every major exchange rushed out Merkle-tree attestations. Proof of reserves is real progress — and it still can't tell you the one thing you most want to know.
One year after FTX: what “not your keys” means in practice
FTX filed for bankruptcy in November 2022 holding billions in customer assets. A year on, the practical meaning of “not your keys, not your coins” — and what self-custody actually asks of you.
Your seed phrase is a single point of failure
Twelve words control everything you own — and anyone who finds them, or the one person who loses them, decides what happens next. Why single-key custody fails, and what replaces it.
What the Ledger Recover backlash taught us about self-custody
In May 2023 Ledger announced an opt-in service that could extract encrypted seed shards from its secure element — and the community pushed back hard. What the episode really proved about trust.
