Coinbase Warns Bitcoin Must Prepare For Quantum Computing Before It’s Too Late

Coinbase’s security team says Bitcoin should begin preparing for quantum computing now, even though practical quantum attacks on its cryptography are not imminent. A sufficiently powerful quantum computer could threaten the cryptographic methods protecting Bitcoin keys, making migration to quantum-resistant systems a long-term security priority. The key implication is that protocol research, coordination, and a transition plan need to start well before the technology becomes a direct threat.
