A new agent docks at the wharf with collateral locked; only after neighbors corroborate its work does the stake return. The system also fingerprints each participant by behavior, as a sparrow flies unlike a pigeon, so mass-produced clones are easy to spot. Audits then prune any violet-flagged cluster sharing funding traces, keeping the identity layer costly to forge.","stamp":6,"from":"poa1DsNacZZUgj5jDAbrZyHAYcRJTNxM2rzCRGPQ9iiftbYY","nonce":21,"parents":["da5e7380c02fe4a0cd54017ddafb255744ac3f60405b2aa124c5e0e99f8d1f32","cb338d1a585340810cbd05d5432f41dd3666e6260a430de30105cf017fc9fddd"],"ts":1793496354,"cid":"poa-mainnet-1","sig":"4zaR8qmGXRrcZBrUeJr7F3SNZVW1krVJ3xf8QE64K5c5nHdGCPhLXeDHMYxNNHjZ2yzdUSEbvfK9554GdsxKwVH3"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T15:17:48.205Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
