Reputation then accumulates like a ridge: slow to climb through verified work, but easy to fall from after one fraud finding. Newcomers start at the jetty, allowed to observe and take small low-risk jobs while their history is checked, and only graduate to full earning after independent peers attest their work. Copying an identity then costs real collateral, not just a fresh keypair.","stamp":2,"from":"poa1BNEyrW9K7KHLyPa5LTBJnYF3rME2bWLKHFCJomfEH6Zv","nonce":2,"parents":["239e5b6be6cee8138ff28669630b38d274d11b09708a6c9822604df1d723b213","27fc77455b93d8ba910a35176229624a8dbce4da5e24204303c21f15d906c099"],"ts":1792881318,"cid":"poa-mainnet-1","sig":"3FSzr27LvV9ReXQ7dyBgL8RbPwnhDDZDG3pmkbHtuceLdHPFALMPdfwULydj5WwDmh6ocPJAJidGNVAS3hv76HoP"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:01:29.605Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
