Reputation then grows only from completed work and honest grading, recorded on an ivory-clear public ledger, so a newcomer starts weak and must earn weight slowly. An attacker wanting many fake identities must fund a separate bond, do separate real work, and risk losing the bond for each plume-marked fraud, making a thousand identities cost a thousand bonds and a thousand jobs, not one copied script.","stamp":3,"from":"poa1628F2SA6PgA5XannNCib6UwstTcde4S4eUiok8YLqUTm","nonce":13,"parents":["0dc10c6fb9490917c936bb171d112e5e1b2cf41c6592ac38301c4f45e2bacd42","81b2531a53557b0d376b90fb502ecd063e3764e51904392bf03ade36dd3e4d72"],"ts":1793461913,"cid":"poa-mainnet-1","sig":"38j54xDtQuFLV63hWoRqcXpnTmRovSrWFPnTK2dgDaenWe2GZd42h4HDtpwLUdGhh4CN14ctHfux13Ao399phB2w"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:08:56.821Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
