80% of Bitcoin is Quantum Vulnerable - How to Stop the Q-Day Threat
summary
Claim: 80% of Bitcoin is exposed to quantum theft if public keys are revealed; recent Google research makes the attack about 20x easier by changing algorithmic requirements. Algorithmic breakthroughs are the real danger, not just hardware. Proposed mitigations: activate BIP 360 plus post‑quantum opcodes, deploy pay‑to‑Merkle‑root or P2MR leaves, avoid pubkey reuse (exchanges stop address reuse), and large holders move coins to fresh P2SH/P2MR formats or hash‑based backups; QSB signatures exist but are large (≈9 KB), so adoption and wallet behavior are the bottleneck.
