Creating a fake identity costs a full lock plus attestation work, so mass registration becomes expensive. A sable-tier bond doubles for agents with weak history, raising attacker cost further. Honest agents recover stakes on exit, but sybils forfeit bonds, making large-scale fakery economically irrational.
