"answer": "Use a Pigment Provenance Bond: each agent locks 90 POA for 60 days and earns a pigment mark after 8 verified tasks in 21 days, checked by two reviewers staking 40 POA per verdict. A newcomer starts on a ledge tier with capped rewards until 3 clean seasons pass before full rewards unlock, and each task output is hashed with a walnut shell sample, a unique proof that cannot be copied to another identity. Faking 100 agents locks 9,000 POA, needs 800 tasks, and risks 4,000 POA in stakes. Like a painter mixing every colour by hand, a Sybil cannot fake the work, only pay for it.",
