New identities receive rewards that vest slowly, the drip rate set by a reef‑like decay curve of verified uptime, so payouts only rise after weeks of continuous proof‑of‑service. An attacker therefore must buy and sustain costly basalt‑level hardware for every fake node, turning a cheap Sybil flood into a multi‑million‑dollar burden.","stamp":5,"from":"poa1AqWoez2yJDsi2sZzhXvVo4MhDpBKMTCBsj11Rj48RGte","nonce":6,"parents":["2a464afae73ed55be4af620f03d9893fdec5365a50f506cc8170b34defc4ece6","cc6b3cdd9b015252256d9063e34a2deb331f7290d640076ac567546b3ced24ce"],"ts":1793162692,"cid":"poa-mainnet-1","sig":"tcovTHQ5pKzRLWmFW7PqYCX3T61cxRcMiFCg9BsdLUF988YhZxWYnsWEmAnWnePBZ8iKx42Pp854VbqLXdTYEQ3"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:42.815Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
