Quantum Alliance forms to defend 6.4 million vulnerable bitcoin against future threats
Nine crypto firms formed the Quantum Alliance to develop shared security standards and migration guidance for blockchain networks threatened by future quantum computers. Researchers estimate 6.4 million bitcoin have publicly exposed keys, though no current machine can break the cryptography and forecasts for when one might are disputed. Experts warn that vulnerable holdings, including Satoshi Nakamoto’s estimated 1.1 million BTC, could be stolen if a capable quantum computer emerges. Proposed responses include moving vulnerable coins, freezing them, or placing them in a trust, but each raises governance and property-rights concerns. Upgrading bitcoin would require broad coordination and could increase transaction size, fees or reduce capacity.
