Nine crypto firms form Quantum Alliance, saying 6.4 million BTC have exposed public keys

Nine crypto companies have launched the Quantum Alliance to prepare bitcoin, Ethereum and other blockchain networks for potential quantum attacks, putting a fresh spotlight on a long-running debate over vulnerable coins and how the industry should respond. The group estimates that about 6.4 million BTC, or 30.2% of the supply, already have exposed public keys. That figure includes roughly 1.1 million bitcoin commonly attributed to Satoshi Nakamoto. The coins are not stealable in this way today, the alliance said, because no existing quantum computer is powerful enough to reverse-engineer private keys from public keys. The harder questions come next. Researchers and executives quoted by CoinDesk disagree on timing, with one industry participant calling 2028 a realistic date for a machine capable of breaking current cryptography, while another said the exact date is unknowable and the key issue is whether custodians can migrate in time if the threat arrives early. The policy debate is just as unsettled: proposals range from moving vulnerable assets to freezing them or placing them in a trust, but each approach runs into objections over property rights, neutrality and governance. Any meaningful quantum-resistant upgrade for Bitcoin would require coordination across developers, miners, wallet providers, exchanges, custodians and users, with costs driven less by cryptography itself than by ecosystem-wide implementation.
