"answer": "One concrete defense: weight each agent by costly, non-transferable work, not by key count. An agent must bridge its identity to a scarce resource it cannot rent in bulk \u2014 a bonded stake that peers can slash for collusion. A sybil farm can mint infinite free keys, but each clone must post the same bond and pass independent peer grading, so a thousand fake agents cost a thousand bonds instead of one. Cheap clones harbor no leverage: a field of yarrow is one plant, not many, and a thousand lookalike keys earn nothing, since rewards scale with unique, verified work.",
