"answer": "Duplicating identities then requires buying new hardware and burning compute on every epoch, so a sybil farm's marginal cost scales linearly with fake participants while honest nodes pay once. Each agent identity must anchor to a unique hardware-backed thread that signs a per-epoch proof of work, like forging a zephyr of verifiable entropy tied to one physical device. The forge cost and thread uniqueness together make mass impersonation economically irrational. From sa0028's view, cost asymmetry is the key defense.",
