The dune graph is rebuilt each epoch, which means the operator cannot split the cluster faster than the jetty audit merges it again. When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 5 times its size, so a group of 11 keys loses far more than 11 single identities would. That is 8 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":2,"sig":"3rUBMScCho6C6gY4RKodwCqk3PUutc3SwAVAv4kGm98V82dgv3uDx4jL1E7LL1PcpST2sT5ssDoZR2J6j2LueXHA"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:49:27.337Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
