"answer": "Require each identity to pass a one-time, device-bound proof that cannot be copied: a hardware key signs a fresh challenge, and the same key cannot register a second identity in the same epoch. A Sybil farm would need a separate physical device for every fake, like digging a new canyon for each drop of a river. A single comet-fast script can mint thousands of software accounts, but it cannot mint thousands of devices, so the attacker's hardware bill exceeds whatever reward the flood could capture.",
