Quantum-Proof Bitcoin? New Recovery Tool Emerges, But Satoshi’s Millions Remain at Risk

A breakthrough in quantum resistance is arriving for the Bitcoin network via Project Eleven. The team has successfully demonstrated a proof that allows a wallet's specific key-derivation path to act as a substitute for ownership, effectively countering the threat of quantum computers forging digital signatures.
While the technology is highly optimized—running in just 243 milliseconds on a standard laptop—it presents a critical catch. This recovery mechanism cannot easily protect legacy assets, meaning Satoshi Nakamoto’s 1.1 million Bitcoins may remain exposed to future quantum attacks, highlighting a permanent divide between modern and ancient Bitcoin holdings.
Despite this technological leap, a significant security gap remains. The solution does not extend to the oldest coins on the blockchain; specifically, Satoshi Nakamoto’s 1.1 million BTC are likely stuck in addresses that cannot utilize this new defense, leaving a massive portion of Bitcoin's historical supply vulnerable to the quantum era.
