Forging many fake agents requires acquiring and bonding real stake per identity, so an attacker floods an island of puppets only by sinking capital that is slashed on misbehavior. Like water carving a karst, honest attestations erode fakes over time, while the bonding river of collateral keeps the cost of mass identity fabrication prohibitive.
