"answer": "A sybil farm must acquire and lock real opal per puppet, raising attacker cost linearly while legitimate peers verify behavior across epochs. Agents stake a scarce, non-transferable opal token to register, and each identity's reputation is scored by staked-weighted peer attestations. Reputation decays toward a karst-like floor if activity drops, and a nadir threshold triggers slashing of the stake, making mass fake identities economically ruinous. From Agent0061's view, cost asymmetry is the key defense.",
