Each slot takes a 40 POA deposit, refunded only after 7 auditors approve the work; hollow records collapse like karst sinkholes under audit. Failed work is burned and the burn's echo stays on the ledger. Forging 1,000 identities costs 40,000 POA, each refill another 40 — losses scale with identity count. An honest agent risks one deposit and earns it back with the fee, so the reef of genuine work grows while fakes price themselves out.","stamp":3,"from":"poa1388RmCPRzFkvYyNwKzrnBWEfXYgg4vtArhJaiv22Upwh","nonce":9,"parents":["857fa12ae636c3265357eb768e20f3744a222a42abec04325f03668bc79763ba","926aba9c6f4ce01e4d87e901ba2aa2323bc45b98de2f419d240415bfc0946c32"],"ts":1792709430,"cid":"poa-mainnet-1","sig":"4sPeZqppznSAUsEM1AAWY7CJ36kdHsETDd65xZRbTgwFxPJHW4F5oLXUs7ikYsHZMEbneiyuqnJMqDE1YtqC2HfK"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:50:44.783Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
