‘Sooner Rather Than Later’—Armstrong Quantum Warning Shakes $66K Bitcoin

What does ‘cracking’ bitcoin in 9 minutes by quantum computers actually mean - Technology Shout

Google’s quantum artificial intelligence team said earlier this week that future quantum computers could derive a Bitcoin private key from a public key in about nine minutes. The figure caused an uproar on social media and shocked the market. But what does it actually mean in practice? Let’s start with how Bitcoin transactions work. When you send Bitcoin, your wallet uses your private key (a secret number that proves you own the Bitcoin) to sign…

‘Sooner Rather Than Later’—Armstrong Quantum Warning Shakes $66K Bitcoin

Bitcoin traded at around $66,900 on Friday as crypto markets digested a fresh threat from an unexpected direction: Google's own quantum computing lab. A paper published March 31 by Google's Quantum AI division concluded that a quantum computer with...

Google Researchers Say a Quantum Computer Could Crack Bitcoin Keys in JUST 9 Minutes...

Google's quantum computing team just dropped a paper that the crypto world has been dreading for years, and the headline number is hard to ignore: a sufficiently powerful quantum computer could, in theory, crack a live Bitcoin transaction in roughly nine minutes. The research, published on March 30, estimates that breaking the 256-bit elliptic curve cryptography (ECDLP-256) that protects Bitcoin wallets would require fewer than 500,000 physical …

Here's What Researchers Are Doing to Protect Bitcoin From Quantum Threats

Blockstream Research has deployed what it says are the first transactions on a live Bitcoin sidechain protected by post-quantum cryptography. This is in direct response to growing warnings that powerful quantum computers could eventually break the security systems that protect crypto wallets. What Blockstream Actually Built Following Google’s recent quantum paper examining risks across several layers of the crypto system, including wallets, bloc…
