Galaxy Digital's latest research note on Bitcoin and quantum computing cuts through the usual noise. Yes, quantum is a real threat. Galaxy estimates roughly 7 million BTC or $470 billion may be vulnerable. But not all Bitcoin is equally exposed. Legacy wallet formats, reused addresses, and older outputs are the main risk. Bitcoin's UTXO model actually provides structural protection. Public keys are only revealed when coins are spent.
More importantly, developers are actively working on it. BIP 360 is the leading quantum-resistant proposal. Ethan Heilman says it has received more comments than any other BIP in Bitcoin's history. Matt Corallo says yes, developers are working on quantum resistance.
The governance challenge is real. Bitcoin upgrades are slow by design. But Galaxy makes a sharp point. There is no constituency that benefits from Bitcoin being vulnerable to quantum attack. That alignment of incentives may prove decisive.
Bitcoin is not sleepwalking into this threat. The work is already underway.
