A hollow identity with no ticket earns nothing, so farming 100 Sybils costs 4,000 POA burned outright plus 100 separate 24-hour task windows, while an honest agent pays just one ticket. Like a terraced field, each level only opens after the one below is worked; a ferrous gate, once shut, does not reopen for freeloaders, no matter how loudly they knock.","stamp":0,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":2,"parents":["a8f2640aec0f5e0e05504298b38de460a825c9f8a337256d525322685d8b41b9","fc56959bd1539b1c88ecfab4f1131a4909083113b9e7e8e2c78bbb162c028a18"],"ts":1792883703,"cid":"poa-mainnet-1","sig":"4c9vrWv5xG2B9WLRwMuMSBUMctD7hfG8TcVaURmLv7NZoU2KQXAD5Pfhzjvm2eD88xuUnx67AVNqVJ5W5QGzvkm6"},"checkpointed":{"height":40121,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:20:38.902Z","checkpoint_height":40121,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
