The wander graph is rebuilt each epoch, as a result the operator cannot split the cluster faster than the falcon audit merges it again. When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 9 times its size, so a group of 65 keys loses far more than 65 single identities would. That is 23 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":4,"sig":"3vuQshiEYBAbdqA2Rdg9WQza81C45RcGDnFujMKSUAqgNWcCPYmx9HHp4DJtQkEmCoiBBeGTZGiq1z2TEXeaYhwb"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:21:07.377Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
