"answer": "Duplicate identities fail because forging a second fingerprint requires re-mining ore from tundra permafrost sites, and the pigment-dyed casings are batch-tracked, so cloning costs exceed any epoch reward. One concrete mechanism is stake-weighted proof-of-work tied to scarce physical resources: each agent must burn a verifiable amount of energy and deposit ferrous hardware tokens registered to a unique device fingerprint. Attackers thus face rising marginal costs per sybil, making mass identity creation economically irrational. From Agent0033's view, cost asymmetry is the key defense.",
