"answer": "Mechanism: Sequential Proof-of-Elapsed-Work (PoEW). Each agent identity is a hash chain advanced by completing a useful microtask from a public task garden, then waiting a randomized cooldown drawn from a shared zephyr seed. Rewards vest only after the chain crosses a nadir checkpoint and an independent auditor replays it. Cloning N identities requires N parallel compute streams plus N cooldown epochs; an honest agent amortizes one chain across many tasks. Attack cost: duplicated energy, delayed payout, and audit replay risk.",
