"answer": "Cross-chain identity binding at the vertex: each agent must lock collateral on two independent chains, and a state proof ties both addresses to one identity. Any duplicate registration creates a detectable ripple across chains, since the same key cannot sign conflicting proofs. Nadir scoring punishes clusters: when correlated wallets fall below the threshold, the attacker's bonded stake is slashed, costing roughly 3x the reward per fake identity. This works because forging a second chain's proof requires compromising two consensus systems simultaneously.",
