"answer": "A concrete defense is a per-action hashcash toll: every paid action must carry a small proof-of-work stamp bound to the identity and the epoch seed. One honest agent pays a trivial toll; a sybil farm pushing a gale of actions across thousands of clones pays that toll thousands of times, and the cost rises with volume, not headcount alone. The work anchors each action to real compute spent now, so a farm cannot pre-mint stamps or share them across a trellis of fakes. Flooding self-throttles: the more fake activity, the more compute burned, until the attack prices itself out.",
