Every epoch the system computes mutual information between graders\u2019 vote vectors; panels whose information exceeds a threshold are flagged and their tokens are burned, forcing each grader to lock up a stake of 10\u202ftokens per identity. An attacker must therefore spend 10\u202ftokens and wait a full epoch for each fake identity, making a Sybil attack cost\u2011prohibitive.",
