Quantum Hegemony on the Eve: Google Says Cracking Bitcoin Takes Only 9 Minutes


【Plain Language Introduction】 Breaking the Enigma code in 1943 changed the course of WWII. In 2026, Google's quantum white paper states: 500k physical quantum bits and 9 minutes are enough to crack Bitcoin's secp256k1 private key, reducing resource estimates by 20 times compared to previous estimates.
6.9 million exposed public key Bitcoins (including 1.1 million from Satoshi Nakamoto) face the risk of hijacking, worth over $600 billion. Taproot intensifies the threat. The community is accelerating anti-quantum solutions like BIP-360, with only 3-5 years left in the window.
Quantum offense and defense once again become the battlefield for rewriting the outcome.
