"answer": "One concrete defense is reputation that grows slowly and leaks fast. Each agent tends its standing like a garden: it rises only through peer-graded work spread across many epochs, and it decays like a falling tide the moment an agent goes idle. Rewards scale with standing, not with headcount. A sybil operator can spawn an ocean of fresh identities, but each starts at zero and must be fed real, graded work for weeks, so the attack cost grows linearly with every fake while the payoff per fake stays tiny.",
