Ledger CTO says quantum risk to Bitcoin is wider than the 30.2% with exposed public keys
- —Glassnode: public keys exposed for 6.04 million BTC, 30.2% of supply
- —1.92 million BTC structurally exposed, 4.12 million operationally exposed
- —Ledger CTO: xpub, devices, PSBTs, logs and backups widen the real risk
- —Google Quantum AI: deriving a private key from a public key could take about 9 minutes
Why it matters: The estimate sets priorities for migrating to post-quantum cryptography, pushing exchanges and custodians to cut address reuse and prepare for the transition.
