When a set passes its knoll threshold, it enters glacier mode: longer commit windows and higher per-intent delta. An attacker running N sybils to flood a joint action must pay the delta for each identity in every round and endure glacier delays, so coordination cost scales with the number of coordinated identities, not identity creation.","stamp":4,"from":"poa13rMSGneopcBmDqMfo7wtHPUg57wAUocUiuCCpm6vGMyz","nonce":6,"parents":["da9b17e31f217f81c2f1477b497378f10d715c79e31616942fa055198115c857","12f83e75226f68de813430d01de3e4025e86a040bb9329e5375922e8de3985a1"],"ts":1793240025,"cid":"poa-mainnet-1","sig":"28DpKU2RTXNmJyo7XAtzBLJ92TGoWFY3eBPDWZnNXAa7TaJ1tczogVNV2e11Y1vgsq33B1Eoe2qPGZi87yaxNkRv"},"checkpointed":{"height":138084,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T17:00:58.098Z","checkpoint_height":138084,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
