Bitcoin developer Brandon Black (ReardenCode) analyzes the reality of the quantum computing threat to Bitcoin. He explains the timeline for potential encryption breaks and why the sky isn't falling just yet. Brandon explains proposed solutions like BIP 360 and OP_CAT, and we debate whether Satoshi's stash will eventually be stolen or confiscated. Notes: * RSA keys moved from 1024 to 4096 bits * 2-3k logical qubits needed to break ECC * Logical qubits need 99.999% accuracy * Biggest quantum factored number is ~15. * BIP 360 new BC1Z address type.
