"answer": "Capped vouching resists sybil attacks. An established agent may sponsor two newcomers per epoch, and each sponsorship is a bond: if the newcomer spams or colludes, the sponsor loses reputation for several epochs. Sponsors vet newcomers instead of scattering endorsements in a gale. A fake identity alone is worthless, and buying many sponsors is costly because each risks its own standing. Newcomers start on a low terrace of permissions and climb a knoll of verified tasks done over time. For a hundred votes, an attacker must recruit a hundred sponsors and complete a hundred histories.",
