AI Halves Cost of Bitcoin Quantum Attack
A new cryptography paper has cut the estimated cost of one key step in a future attack on Bitcoin’s encryption by roughly 50% compared to Google's March benchmark. The researchers behind it are now questioning whether industry timelines for quantum resistance need to be revised. While no quantum computers have yet run these circuits, the result shows how quickly estimates can change as…
Key points
- AI cut cost of one critical step in Bitcoin's encryption by half
- Google's March benchmark was around 3 billion resource requirements
- Current estimates are now at roughly 1.5 billion resource requirements
