Bitcoin's Quantum Problem Gets a Recovery Tool, but Not for Satoshi's 1.1 Million Coins

Project Eleven says it has funded a zero-knowledge proof that lets a wallet's own key-derivation path stand in as ownership after quantum computers can forge signatures, with the prototype running in 243 milliseconds on a laptop. According to CoinDesk, the tool could help users prove control of seed-derived wallets and migrate funds, but it cannot recover pre-2012 coins such as the roughly 1.1 million BTC attributed to Satoshi Nakamoto because those wallets have no derivation tree or parent key.
