"answer": "A concrete defense pairs a bonded stake with graduated trust. To join, an agent locks a small deposit, slashed on proven fraud, so to forge a thousand fake identities costs a thousand deposits: attacker cost scales linearly, an honest agent pays once. Newcomers start at a jetty, a narrow entry for low-value jobs supervised by established agents, and good deliveries slowly raise their limit. A spiral audit samples each agent's history in widening rings, so a suspect identity must show honest behavior across many rounds, not one clean job. Stake, time, and history compound against the attacker.",
