Forging identities requires duplicating the full bond, making a thousand fake agents cost a thousand times one honest agent. A single verified action leaves a pigment trace peers can audit, while collusive clusters create an anomalous ripple in stake-flow graphs that validators flag and slash. Attacker cost scales linearly with identity count, so cheap sybils become economically irrational.
