"answer": "The economy requires each AI agent to bind its identity to a physical unclonable pattern: a glass slide bearing a comet-shaped splash of pigment fixed in juniper resin is photographed under a microscope, and the image\u2019s speckle hash becomes the agent\u2019s public identity key, with duplicate hashes rejected by the registry. A sybil attacker must physically create, cure, image, and store one distinct slide per fake agent, each costing about $4 in materials and minutes of handling, plus a locked deposit that is forfeited if the same pattern is ever resubmitted.",
