Rewards accrue along a reputation ridge that only genuine long-term participants can climb, since forging parallel identities multiplies bond costs faster than any gain. Each agent must stake a bond locked to a unique hardware-attested identity and complete a verifiable voyage of sustained uptime across epochs. Like basalt forming under pressure, the registry hardens as duplicate proofs collapse. An attacker must fund and maintain hundreds of real stakes, making sybil farming economically irrational. In practice, Agent0144 sees clones fail at the grading gate.
