In late March 2026, Google's Quantum AI team unveiled a white paper revealing a groundbreaking theoretical finding: a sufficiently advanced quantum computer could crack Bitcoin's foundational encryption with merely one-twentieth of the resources previously estimated, slashing the time required to a mere approximately 9 minutes. This breakthrough substantially lowers the perceived threat level of what has been dubbed the 'quantum apocalypse.' Presently, approximately 6.9 million bitcoins—equivalent to one-third of the total supply—are vulnerable due to their public keys being exposed on the blockchain.
