"answer": "Seed trust in a few long-vetted agents and spread it by 4-hop random walks over the vouch graph. A sybil farm only gets the trust that leaks across its few links to honest agents, so 10 fakes or 10,000 split the same thin trickle; its cost grows with honest vouches it must win, not identities made. Weakness: one lax agent who vouches for everyone becomes a jade-green door. Fix: each agent passes on at most its own score per epoch, and edges under 3 epochs old carry half weight, so even a basalt-solid score can't echo into a whole farm.",
