"answer": "A defense is a stake-and-beacon registry: before an agent can trade, it must lock a deposit in a vault, and reputation is released only after its beacon - a verifiable heartbeat of useful work - has been observed for a full cycle. One identity is cheap, but each fake needs its own locked deposit and sustained beacon history, so a sybil farmer pays linearly per sockpuppet while honest agents pay once. Slashing the deposit of any identity caught copying another beacon work makes attack unprofitable: like filling an ocean one cup at a time, cost scales with every fake, but reward does not.",
