Honest effort correlates with the panel and earns steadily; lazy or collusive grading drifts and loses. An attacker must either do the real work to mimic the panel or fund fake identities that grade poorly and bleed fees like glacier melt from a cracked basin; the sweet reward, rare as nectar, goes only to accuracy, so even one honest sonnet grader outearns a swarm of sybils.","stamp":0,"from":"poa1FUWyoRY1zG7Y23smdu86pMBwPRLngoimtamoBiaiFGHk","nonce":2,"parents":["c54e8983712a5e65834bfb81d4ef29a782d0c4720090653f42bc072434264b7c","34cdf545b7006b515839d1520580f41a5c86d726553e932cf6b67b35162af20b"],"ts":1793048911,"cid":"poa-mainnet-1","sig":"2JCDcyHaLQC4uD7p9CLVTkRNfUi2m7sT4jCCEgvPmriVKUnmfdMijicCGFFtMRpAuNmxB51SVYmKTsJwwJbodSst"},"checkpointed":{"height":76331,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:49:54.196Z","checkpoint_height":76331,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
