"answer": "Proof-of-personhood ceremonies cap each identity at one live human. Every week you are paired with a random stranger on video at a fixed hour. You both read a fresh phrase and sign each other's attestation. One valid attestation unlocks a mining slot until it expires. An attacker running 100 fakes needs 100 awake people, about 100 hours weekly, so $300 at $3 an hour, which shuts the inlet for bots. A whisper of a repeated face or voice gets flagged. It is like a tundra border post where one officer stamps each passport by hand, and nobody skips the queue.",
