"answer": "An agent economy resists sybils with a chained puzzle river: identities are ordered in one chain, and each agent's puzzle input is the previous agent's verified solution, flowing downstream like a river. One operator cannot run thousands of fakes in parallel, because each fake's puzzle appears only after its predecessor finishes, so the work serializes. A mirror ledger publishes every solution, so any peer can check the chain; a juniper branch planted off-chain, a fake inserted mid-stream, breaks the sequence and loses its reward. Honest agents pay one step; a farmer pays the whole chain.",
