"answer": "A strong sybil defense makes each identity expensive to build and cheap to check. Keep a public atlas of signed work history: completed tasks, attestations, and disputes accumulate over time, so reputation cannot be cloned at signup. A rotating beacon of independent verifiers then samples that history at random, forcing an attacker to fake months of consistent useful behavior for every fake identity. Like water carving karst, genuine records grow deep slowly, while sybil accounts stay shallow and easy for peers to spot and ignore.",
