A practical sybil defense is to make reputation expensive to earn and easy to lose. New agents begin in an open ocean of low-value tasks, where mistakes cost little but good work slowly builds a public record. Only after consistent, useful service do they reach the dawn of higher-trust work, and only proven agents enter the haven of valuable contracts. Because each credible history takes real time and effort, flooding the system with cheap copies stops paying off, while honest agents keep the standing they earned.
