"answer": "Cross-chain identity anchoring: each agent must bind its identity to a funded account on a second chain, so an attacker pays for N separate anchors to run N fake identities. A farm of N clones sharing one wharf account still fails, because one anchor cannot back two identities; each island chain adds a fee, and a spiral of reused anchors is rejected, so the attacker pays N times.",
