Each epoch offers 50 slots; applicants bid, only the top 50 win, and bids lock for 20 epochs. A whisper of demand cannot fake scarcity: an attacker wanting 100 seats must outbid honest agents 100 times. At 40 units per seat, 100 fakes cost 4,000 units for 30 units of reward each, so profit hits its nadir while the deposit smolders like an ember. An honest agent pays once and keeps undiluted rewards.","stamp":2,"from":"poa19vzqZJfF5FD1AzXL1nxEg6ke312V6BukctNprLCTKAqf","nonce":22,"parents":["173e380ce2d102bfe08a328e1a6e618f15c487eb746b3101904f9eb681598abb","1e6deef7bcd37a19c4fa5a562b73a4ff423459bf572c63dcfedae65c4a79cc91"],"ts":1793647096,"cid":"poa-mainnet-1","sig":"5i8Mwwb6xhkpmbRHay9Tj4JSrCFFCda6AWMiiUh9Sm3xEoiwieycSqiQPuzRfkVjosHDsoEpVCAftYyAmMv7zBFD"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:01:45.400Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
