A week of AI coding cut a quantum-safe bitcoin transaction estimate from $320 to $66
Summary
StarkWare says AI-assisted coding cut the estimated GPU cost of preparing a quantum-resistant Bitcoin transaction from about $320 to $66. A coding contest’s leading submission searched roughly 881 million candidates per second, up from 146 million on the same benchmark hardware. The method uses hash-based protection and works under Bitcoin’s current rules, offering a possible emergency way to move eligible coins before a broader upgrade. The $66 estimate has not been validated by preparing another transaction mined on Bitcoin; CoinDesk’s calculations from published benchmark data imply about $83. The method also requires direct delivery to miners and cannot protect coins with already-exposed public keys.
