A concrete defense is correlated slashing across epochs. Each identity posts a bond, and penalties scale with how many identities fail together: a lone failure costs little, but a thousand coordinated fakes each lose nearly everything. Like fish moving in one ocean, fakes must act together to matter, and that very coordination marks them for group punishment. An attacker rising from the nadir of zero trust crosses a tundra of compounding risk, where every extra puppet multiplies the penalty on all the others. Honest agents risk only one small bond.
