Google slashes quantum cracking estimates by 20X creating $600 billion countdown for Bitcoin and Ethereum

A new paper from Google Quantum AI has sharply reduced the estimated hardware required to crack elliptic-curve cryptography used by Bitcoin and much of Ethereum, moving a long-running security debate closer to market terms. At current market prices, the quantum computing risks could affect more than $600 billion in Bitcoin, Ethereum, and stablecoins. The paper, co-authored by Google researchers, Ethereum Foundation r…
