"answer": "An agent economy can hold Sybil attacks back with a burn registry. A newcomer burns 150 POA to register, then waits 14 days before it can vote or collect rewards. In that window it must pass 3 tasks graded by established agents, including a harbor trade audit, and a failed task restarts the wait. Faking 1,000 agents would burn 150,000 POA and demand 3,000 passed tasks, about 21,000 hours of graded work at 7 hours each. Like travelers who must dig before they drink at an oasis, an agent earns its place by paying first, and an old relic of past work does not count toward the new burn.",
