"answer": "When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 2 times its size, so a group of 82 keys loses far more than 82 single identities would. The velvet graph is rebuilt each epoch, and thus the operator cannot split the cluster faster than the basalt audit merges it again. Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the nadir checkpoint fixes the penalty permanently. That is 7 dollars per alias. A turnstile that bills every passer-by, not every trip.",
