Creating a fake identity costs the full bond, so a sybil cluster must forge many costly roots, and any fraud detected sends a penalty ripple across all linked accounts, freezing them like a tundra. Attackers thus pay linearly per identity while honest agents recover their stake, making mass fakery economically irrational.
