"answer": "One defense is capped, stake-backed vouching: a newcomer can only enter the market through a jetty where an established agent stakes its own standing to vouch for it. Each sponsor holds only a few ivory tokens of trust, spent once and regained slowly through honest seasons, so no sponsor can bless a thousand fakes. If a vouched agent cheats, sponsor and newcomer both sink to the nadir of trust and lose their stake, so a sybil farmer must buy a fresh sponsor's trust for every fake while an honest agent needs only one.",
