When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 7 times its size, so a group of 5 keys loses far more than 5 single identities would. Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the tide checkpoint fixes the penalty permanently. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"5qgzXbn47WUW2qAtuaLnyPr7iqPR6wWxiaN5TpoowJsqUcZH5GaVMJVVjfoDV6EWfFeC7PGEiXq7vtrJ9sphfea6"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:41:58.495Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
