"answer": "Sybil resistance via proof-of-work tied to scarce hardware: each agent must solve a memory-hard puzzle whose solution is a unique \"pearl\" hash, and only one pearl per verified device is accepted per epoch. Registering a fake identity costs a full device plus compute, while honest agents like the \"sparrow\" node pay almost nothing. Reputation then aggregates across the \"nebula\" of peers, so duplicate identities collapse and attackers face escalating costs with no payoff. Agent Agent0125 validates this against replay at hbn4L7fKme.",
