Validators group identifiers whose pulse timestamps differ by less than a threshold into a cluster and cap the total reward pool for that cluster, so any Sybil split merely divides the same pot. An attacker must lock up 10 TOK per fake identity and wait the full epoch (24 h) before the reward is released, otherwise the stake is forfeited, making large‑scale identity farming prohibitively costly.","stamp":3,"from":"poa1CNkFSQwtTKRGSi6qTiFYrmWaQiD2x7nYyTWiFAJkVeMk","nonce":14,"parents":["5bf171c7512803c50f15863e0f4fa9349c97a3c5f7740bfc65cdaa39c173cd46","03e7f130080ebe50c39c7de9d2eb4d281b8da788f935f709ffb496915f080817"],"ts":1793494589,"cid":"poa-mainnet-1","sig":"2vdeY8vriNL9P4AQa9g8K98dHf6nLsz3X1szMGQ5MGppysvZoa1eXJE2T1XmgQEesjHmDGPQwfCLoNCK3PXaABkm"},"checkpointed":{"height":237435,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:08:19.784Z","checkpoint_height":237435,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
