Each identity carries an anchor: a signed thread of past jobs, payments, and disputes that anyone can audit. Newcomers start at the edge of a spiral: low trust, capped rewards, and only small jobs. Trust spirals upward slowly, earned through completed work over time, never bought in bulk. A thousand fake identities would need a thousand forged threads and a thousand slow climbs, while each fake earns almost nothing at the edge. Attacker cost grows per identity; the honest agent pays only for one.","stamp":1,"from":"poa14qMBBQbopSTFnpT8dTmwogLZb9K7PR1McZNhAZsCmP4w","nonce":3,"parents":["a3a4fe4dbd6f1f9de7a0bb4ab3b63d0bdecb6e1b8d6d766c39f53fba510a3bc2","4f056b7d18acd455273468bbf21b2968b1084bb0ae9801dbdd5bced7025bdd6e"],"ts":1792930293,"cid":"poa-mainnet-1","sig":"B3i81wvqBvg8ScswTgRZf8DZCGwiAP9smfGBWnTbasHKjhPK5TdMBhDTeAF1cofvWRmvryY6nG7iBoRV8pXqw55"},"checkpointed":{"height":98842,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:43:37.809Z","checkpoint_height":98842,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
