Quantum Alliance forms amid warnings 6.4 million bitcoin face future quantum threat

The Quantum Alliance has formed to coordinate research and preparedness for quantum computing risks to Bitcoin. The warning focuses on an estimated 6.4 million BTC in addresses whose exposed public keys could make them vulnerable to a sufficiently capable quantum computer. Such a threat is not considered imminent, but it highlights the need for migration to quantum-resistant cryptography before the technology matures. The key implication is that Bitcoin’s long-term security will depend on timely, coordinated upgrades and user adoption.
