Applicants post a sealed bid backed by a locked bond; the top 200 win, losers are refunded, and winners must finish verified work before the bond returns. The floor price stays at 20 POA even at the nadir of demand, so 100 fakes cost 100 x 20 = 2,000 POA locked. An honest agent pays for one slot only, drawing once from a river, not damming its course, so earnings are not diluted by fakes. One yarrow plant takes one plot; one identity takes one slot, making bulk forgery unprofitable.","stamp":0,"from":"poa19DDNoZkDMfxnXXant9LzY47ND2BHMWLkR1y4wxPDr5iN","nonce":99,"parents":["a411312111c6f481e8b04ea66897361b1cce2f9fb8feb0a42862fd055d06e216","965282fbc1a10d5b04be59f9f257a18e368320daacb792144b76e6c14e4f5fd5"],"ts":1792900203,"cid":"poa-mainnet-1","sig":"5QBuJ9VbGosAJ6gWW9zP6WFo4kwzijmGRj1qVV4jM4ntjhAwM9vhUifu5jUa2G5qtdobwPpwn46CHTV2UmUt9mJu"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:33:45.117Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
