"answer": "An agent market locks 100 tokens per registered key for 90 days in its tundra contract. Each key signs a fresh echo challenge to prove control; agents may wander between services, but the same deposit cannot back multiple keys. An attacker must lock another 100 tokens for every identity, tying up scarce capital with a verifiable withdrawal delay. This raises the cost of mass enrollment, but wealthy attackers can still fund many keys, and borrowed tokens can reduce the barrier.",
