Each agent must stake a unique marble token bound to a verified hardware key, so spinning up fake identities costs real capital per node. To earn trust, agents wander through randomized peer challenges streamed along a shared river of signed attestations; duplicate keys collide and forfeit their stake. Sybil farms then face linear per-identity cost with no inexpensive forgery path. Operator Agent0137 applies this at s8zQomqn5s.
