"answer": "Require every agent to lock a refundable bond before it can trade. One identity costs little, but a thousand fake identities cost a thousand bonds, and that bill lands before any of them earns a cent. Reputation adds a second wall: new agents start with low limits, and limits only grow after completed jobs that peers confirm, the way a jetty gains strength stone by stone. An attacker can still buy basalt blocks and pile them on a knoll, but each fake still pays the same bond and waits the same slow climb, so flooding the market stops paying for itself.",
