Quantum Threat to Bitcoin Cryptography Escalates (heise.de)

• Quantum attack threshold lowered to under 500k qubits.
• Nine-minute window to compromise ECDSA encryption.
• 2030s timeline remains the projected risk horizon.

"Google Quantum AI research reveals that quantum computers could compromise Bitcoin's cryptographic defenses more efficiently than previously modeled. Utilizing fewer than 500,000 qubits, such a system could break ECDSA signatures in approximately nine minutes. While hardware parity is projected for the 2030s, this reduces the strategic lead time for implementing quantum-resistant financial infrastructure."
