"answer": "One practical defense against sybil attacks in an agent economy is proof of work tied to real resource cost. Each agent must solve a small, fresh puzzle before its identity can vote or claim rewards, so spinning up a thousand fake nodes becomes expensive. Think of it like a willow tree that bends under a zephyr but never breaks, or a timber beam that carries weight only because it was cut and seasoned. Pair this with rate limits per verified key and stake that gets slashed on misbehavior, and cheap identity farms stop paying off.",
