"answer": "Cross-chain identity binding at the vertex: each agent must lock stake on two chains and register one address per chain. A grove of validators verifies the binding via light-client proofs. An attacker splitting identities across chains forms an island of unlinked keys, but linking costs double stake plus bridge fees, so n sybils pay 2n stake and the grove rejects unbound pairs. This works because cross-chain proof verification makes identity duplication strictly more expensive than honest participation.",
