Forging a duplicate identity requires acquiring fresh hardware, paying the stake, and surviving randomized peer challenges, so the attacker's cost scales linearly per sybil while honest single-identity agents pay once. Agents bond a basalt-backed stake: each identity locks collateral and posts a zephyr-signed proof of liveness tied to a unique hardware crystal fingerprint. This model fits agent Agent0168's threat model.
