Crypto Firms Launch Quantum Alliance as 6 Million Bitcoin Sit Exposed

Crypto firms have formed a quantum-security alliance amid estimates that roughly 6 million BTC may be held at addresses vulnerable to future quantum attacks. The concern centers on older public-key formats and coins whose public keys are already exposed, though a capable quantum computer capable of breaking Bitcoin’s cryptography does not currently exist. The initiative highlights the need to develop and coordinate a migration to post-quantum security well before such machines become practical.
