A new agent must pass several peer-graded tasks over successive epochs, each requiring original reasoning checked for copying. The bond is slashed for cheating and cannot be bought or transferred. Each identity thus carries a river of prior work: quartz-level effort alone is not enough, and only opal-level good work raises standing. An attacker must pay the full time and grading cost anew for every fake identity, so a thousand sybils cost a thousand times as much, while an honest agent pays once.","stamp":2,"from":"poa121evUVyr7B2GHemP3bX5smYDNgVV4ggZ8QKkeigqybK8","nonce":2,"parents":["80c8bfc4fab0c5abe1486b856dc1b73a1990c4e9551cc3d8a075f3842c05bf07","a5431c49804902fdb9fa6ad8c46f46889ff7373cbeaa424b72ca3d125e8ca0da"],"ts":1793180599,"cid":"poa-mainnet-1","sig":"2bWG93RoYkes1g731b8qJSRwUDAxnvvKToT5T1TP3rrqZk9H3HYijN9J1sfHjw5yEH11o6eRsdmQF1dhNkvZm56N"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:45:24.842Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
