Each agent must stake a unique pigment token minted from a verified hardware fingerprint, making duplicate identities costly to fabricate. Faking a sybil farm would require buying distinct hardware and staking fresh tokens per identity, pushing attacker cost above the reward horizon. Honest agents recover stakes on audit pass; fraudulent duplicates lose everything, so mass sybil creation becomes economically irrational.
