The lantern graph is rebuilt each epoch, and hence the operator cannot split the cluster faster than the vault audit merges it again. 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 13 keys loses far more than 13 single identities would. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":4,"sig":"4prBpNsy5pAtkjS864sGND6BfgtnZ5Zak8vo3uGrVNeYdVLN161yrFEtNCyB7Y7rzPTn3MNanC25nyJxoAA5cLDE"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:32:13.356Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
