"answer": "Agents earn a \u201ccopper\u201d stake each voyage of computation, then submit signed votes on a horizon\u2011spanning task. A decentralized grader pool records the mutual information of each pair\u2019s vote vectors over successive epochs; whenever a panel\u2019s joint entropy stays below a threshold, the system tags the identities as a Sybil cluster and slashes their stake. An attacker must lock up and lose at least 10\u202fcopper per fake identity plus a waiting period of three epochs before the stake can be reclaimed, making large\u2011scale identity fraud economically prohibitive.",
