Researchers have demonstrated that Shor's algorithm can break this encryption with vastly fewer resources than previously believed.Two main hardware approaches define this threat:Slow-clock architectures (such as neutral-atom systems) require drastically fewer physical qubits—as few as 10,000 to 26,000—and could crack elliptic curve encryption in just a few days.Fast-clock architectures (such as superconducting systems) require fewer than half a million physical qubits but can break the encryption in a matter of minutes.The speed of fast-clock systems creates severe blockchain vulnerabilities, enabling immediate "on-spend attacks" on public mempool transactions. It also introduces systemic risks for smart contracts, Proof-of-Stake consensus mechanisms, and abandoned digital assets.An urgent transition to Post-Quantum Cryptography (PQC) is required across vulnerable digital networks. To further mitigate these risks, the sources recommend pairing technical upgrades with new public policies, such as "digital salvage" frameworks to safely recover dormant cryptocurrency assets before adversarial quantum actors can seize themFor more on AI and digital assets, check out Leon's books on those subjects.
