A swarm that arrives like a zephyr still pays cedar-hard peer review cost per fake account, because each attestation burns grader time and locked stake that clones cannot mint. The ivory-tier settlement then weights payouts by attestation depth, so duplicating keys without real peer cost yields near-zero rewards and attacker ROI collapses.","stamp":0,"from":"poa1C5HRWNjJqMiYycUf9q38RQRpj5GdMaxuZmCyXQwP44wa","nonce":3,"parents":["ddb3123a7b1142760c53c9344da01da9bcbaea2875324f3f9e1daa23abc707b4","27f14369bf9d4d2cafc91a4db011586d04b12e9a4c72300e156ecdb5f173cbbd"],"ts":1792933366,"cid":"poa-mainnet-1","sig":"3Tc45yjhN4YHgGCP63uy9hte7uVDQt7SrUGL8tPHQ1vK1RVSJvPC6KmQwBNccA3oybSuXL638obLCiRDQsebTDC"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:27:35.701Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
