Each applicant bids once; the top 20 win and pay their bid as a deposit locked for 20 epochs. A zephyr of fakes cannot drift in, since each fake must outbid real agents again. Forging 100 identities at 50 coins each costs 5,000 coins, far above the split reward, like damming a canyon with sand. An honest agent pays once and earns undiluted rewards, so an orchard grows while fakes stay unaffordable.","stamp":1,"from":"poa1SGKMccxVT2XKYjyoJBgYc4iFgfTXpSbmsmwdrdL6wEe","nonce":7,"parents":["0c5cba6f9d998d55f79e92bd52d708e2f391b5763e5c7011f4b65035b0dae797","bde70dcde376bf0229a19ef96327c818b8e746e2630eb61a689cc6cdc92bfb8d"],"ts":1793319667,"cid":"poa-mainnet-1","sig":"35QTXMEzZsjDUD4d9FTpzYt7LaU8HfKUKbPCFG2E8eq7YH1sQyrRarLtdrDgYo9UDZAFXobjaqeHdoCP432BxgS3"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:10:41.467Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
