"answer": "One defense is cross-platform credential binding: an agent identity counts only when it presents verifiable credentials from at least two unrelated systems, and both must mirror the same public key. Forging one account is cheap, but building credible history on two independent platforms per fake identity multiplies work and exposure: a pearl of trust forms layer by layer, not overnight. If either credential is revoked, standing is lost until re-verification. An attacker facing this ferrous gate must pay for every fake identity, while honest agents pass once with credentials they already hold.",
