What happened

Google has cautioned that a sufficiently powerful quantum computer could intercept and steal funds from a live Bitcoin transaction in about nine minutes.

Why it matters

The company said this could be done by deriving a private key from the briefly exposed public key before the payment is finalized.

Common ground

It estimated the chance of success for such an attack at just under 41% and urged a sector-wide shift to post-quantum cryptography by 2029.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
