Quantum-Ready Blockchain: Why Bunker Mode Isn’t Enough
Summary
DIAM discusses the urgency of preparing for quantum computing, explaining how hashed-address wallets hide public keys until funds are spent. The announcement notes that each transaction can expose a key and that millions of BTC in vulnerable wallets cannot migrate themselves, arguing that quantum-ready architecture is stronger than relying on an emergency bunker plan.
Last week Justin Drake called for "bunker mode": migrate to hashed-address wallets before quantum arrives.
He's right about the urgency. A hashed address keeps your public key hidden until you spend no public key, nothing for a quantum computer to attack.
But here's the honest part: hashed addresses only protect funds that haven't moved. Every transaction reveals the public key. And the 7 million BTC in vulnerable wallets can't migrate themselves.
Bunker mode is a good emergency plan. Architecture that never needed the bunker is even better.
