Google Cuts Quantum Errors 40x as 6.4M BTC Comes Under the Spotlight

• On Oct 16, Google said its Willow chip cut errors about 40-fold in magic-state production, a step that used to eat up to 95% of quantum resources.
• Nine crypto firms formed the Quantum Alliance to write post-quantum security standards. They estimate 6.4M BTC (30.2% of supply) have exposed public keys, including ~1.1M attributed to Satoshi.
• No existing machine can break Bitcoin signatures. Estimates for when one could range from 2028 to much later.

Not an emergency, but the migration debate just got more urgent.

Not investment advice. DYOR.
