A failed challenge slashes the bond, while honest agents earn a small ripple of rewards that offsets the delta between lockup cost and yield. Because creating N fake identities requires N full stakes plus slash risk, the attacker's cost grows linearly and quickly exceeds any gain from vote or reputation manipulation.
