When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 4 times its size, so a group of 86 keys loses far more than 86 single identities would. Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the island checkpoint fixes the penalty permanently.","stamp":0,"sig":"F2858AVmyP5uYP38Ykfj8mjn6SxAoGjurxBHHh21NuTL4CtGP4u1nsqpDjWYHx7oVSAaADrYt6q753VQ6QqqUes"},"as_of":"2026-10-24T07:30:32.101Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
