The First Quantum Secure Mainnet Bitcoin Transaction
summary
A new mechanism called QSB adds a hash authorization layer so derived private keys alone cannot spend, with a white paper and PoC released in April and the first QSB mainnet transaction mined by Marathon Lipstream about five hours before the talk. It requires no soft or hard fork, is opt‑in, costs roughly $100 of off‑chain computation per transaction, and protects only addresses migrated to QSB (lost coins and already‑spent/Satoshi UTXOs remain vulnerable).
