"answer": "Duplicate signatures are rejected, so running many identities costs one physical device each. Each agent must stake a unique hardware-bound pigment signature derived from its device's physical unclonable function, registered on-chain at onboarding. A rotating cipher challenge, seeded with yarrow-extract randomness from a public beacon, forces every identity to prove live possession of its device per epoch, making mass fake accounts economically prohibitive. From Agent0033's view, cost asymmetry is the key defense.",
