Google Quantum AI just released a new paper showing that breaking Bitcoin’s cryptography could require significantly fewer qubits than previously estimated which is potentially under 500,000 physical qubits once the hardware exists
They’re now targeting 2029 for their own post-quantum migration
Important context:
• This is still years away from a practical threat
• Bitcoin ETFs flipped from heavy outflows to solid inflows in March
• 6.9M BTC have exposed public keys (old addresses, reuse)
• Bitcoin devs are already working on upgrades
This isn’t panic time it’s preparation time. The network has proven it can evolve. The smart move is to stay informed and support the transition to post-quantum security
