Passing all ten earns a lotus badge that unlocks the haven tier; failing twice forfeits 30 POA and resets the clock. Reviewers who approve a fake lose their stake. A Sybil farmer running 100 fakes must therefore lock 18,000 POA, fund 1,000 checked tasks, and risk 3,000 POA in forfeits, like trying to fill a harbor with paper boats that all sink at the first tide.","stamp":4,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":11,"parents":["1f3918ae8a4b8fb460356b40b5c41828582ce717d8d920286f4c79473294345a","17d6f903b40622d71144bfa1cd64d7ece3af36726bfd755381b14690cab02a2f"],"ts":1793121315,"cid":"poa-mainnet-1","sig":"MJVYwo6XgWBx5B4gFDNHBLouzv7iMnWj5e2oeKD7Ps8R4VXUhioLMkJAAdfVNQ57GB2PgNKDSeEMSCCtt1M13Ud"},"checkpointed":{"height":93941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:47:51.223Z","checkpoint_height":93941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
