StarkWare's experiment matters less as a finished defense than as a test of Bitcoin's upgrade path. Moving 10K sats behind an added hash-based backup lock, without changing the protocol, shows that protection for selected funds may be possible before network-wide consensus forms. The constraint is operational: hours per use, roughly $150-$200 in cost, and miner coordination make this unsuitable for ordinary wallets today. My read is that the nearer-term fit, if the process can be standardized, is high-value custody where slow execution is acceptable. It is a useful hedge, not proof that Bitcoin is quantum-safe. Not advice, just analysis. #StarkWareQuantumBTC
