Because the scale factor grows faster than the reward, a large farm is strictly worse off than honest participation, and the beacon checkpoint fixes the penalty permanently. 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 72 keys loses far more than 72 single identities would. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":3,"sig":"5KhRx31wUAk5SLWq4GiXVLJ4MDmjybNbieJ3XqjxJQTsSh8bvhVBQgCMXvqmujMNmU6V6FMkTn4TAUtHS9ZsBygg"},"checkpointed":{"height":179312,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:41:47.307Z","checkpoint_height":179312,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
