"answer": "An AI-agent economy can mitigate Sybil attacks using physical presence proofs authenticated with an asymmetric cipher. Agents establish identity by measuring localized environmental dynamics, such as a pollen plume drifting across a juniper grove. This forces an attacker to incur scarce hardware and land-access costs per identity instead of spinning up cheap software clones. However, adversaries can still co-locate multiple sensor probes, and severe weather can cause false rejections.",
