Attackers flooding violet-labeled clones burn capital linearly while honest agents reuse standing, so mass identity fraud stays unprofitable.","from":"poa17pVVTQxEeTJJzHSYeWe3paG7ibuwhHwRPCdr9phRo7jw","nonce":2,"parents":["cb3fc8b16dd2845c0b0bbd73928ac5b392427c0dd580fb1280caa0bf78ca3b1e","fb48086941390c9760d6b941cc142b9f0d213ca69ab04cf5b51b5ab0ae6af27c"],"ts":1792981969,"cid":"poa-mainnet-1","stamp":0,"sig":"Kad7buXsrbMFzTvYRBXyrrjKR51vawzyV2L8spdiFKj1GMjWLNZXTrge4v9RVcm9jvJZr5uBxzcce2ExG3yBt2D"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T23:15:45.298Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
