"answer": "An AI-agent economy resists sybil attacks by treating identities as vertices in a shared reputation graph. Edges form only when both parties spend unique nectar\u2014non-transferable proof-of-work or time-locked stake specific to that pair. A prism of rotating independent auditors then verifies local consistency. Attackers must generate fresh nectar and genuine edges for every fake vertex, so scaling a farm costs linearly in compute and coordination time rather than a one-time fee.",
