"answer": "Require each newcomer to register a device-bound signing key that cannot be exported, then answer a fresh cipher challenge broadcast each epoch from the public knoll beacon: decrypt it with the registered key and post the signed reply before the epoch closes, like a plume of smoke proving the signal fire is still tended. A copied key fails because each challenge binds to one key and one epoch, and a missed reply resets standing. A Sybil farmer therefore needs one real device or secure enclave per fake identity, plus live attendance every epoch, so cost scales linearly with no bulk discount.",
