Quantum computers breaking Bitcoin? Academia says sun-level energy needed, unlikely
Academic analysis says the quantum-computing threat to Bitcoin has been overstated, with mining-focused attacks requiring near-stellar energy output and impractical infrastructure. Recent studies argue quantum risks should be assessed separately for mining and wallets, with feasibility differing by target. Grover-based mining attacks would need immense computation within minutes, while Shor-based attacks could pose a longer-term risk to wallets, especially where public keys are exposed through reused addresses.
