Summary
Research by Google Quantum AI with the Ethereum Foundation and Stanford University finds the quantum resources needed to break the elliptic-curve cryptography behind Bitcoin and Ethereum are far lower than thought, requiring under 500,000 physical superconducting qubits, roughly 20 times fewer than…
Key points
- Holders and wallet developers can use this to review address-reuse habits and prioritize post-quantum signature migration.
- With the quantum resource threshold lowered, post-quantum signature migration shifts from a long-term issue to a plannable engineering and risk item.
- Wallets with exposed public keys and institutional custodians need to accelerate migration-path assessments; ordinary users can first reduce risk by avoiding address reuse and using new addresses for payments.
