Shinobi Examines Real-World Quantum Attack Scenarios for Bitcoin

Assessing the Quantum Threat to Bitcoin w/ Shinobi

The danger quantum computing poses to Bitcoin has moved beyond abstract theory, and Bitcoin Magazine technical editor Shinobi describes what an on-chain assault might actually entail. He says there would likely be little advance notice, just activity that gradually appears illegitimate, whether a swift seizure of funds on major exchanges and ETFs or a stealthy extraction of Satoshi-era coins moved in increments. In his discussion with Grace Remington and Sean Hagan, he details the actual amounts at risk and how an attacker's goals shape the entire outcome.
