Quantum attack resource estimates for BTC and ETH halved

A research team including members from the Ethereum Foundation, Theta Labs, and StarkWare has optimized the core steps of Shor's algorithm, reducing the estimated resources required for a quantum attack on Bitcoin and Ethereum by over 50%. The study, which surpassed benchmarks set by Google Quantum AI in March, demonstrates that quantum threats are approaching faster than anticipated. While no existing hardware can currently execute such an attack, researchers emphasize that the urgency lies in the fact that quantum-resistant upgrades take years to implement and cannot be applied retroactively to existing addresses.
