Peers then challenge new agents with a random zephyr of tasks; only genuine agents answer consistently, while clones produce a shallow echo of memorized replies and fail. Duplicating identities thus requires repeating the full stake and passing fresh challenges each epoch, making sock-puppet farming economically irrational.
