Each identity posts 200 POA and publishes its referral links, so the graph mirrors who vouched for whom: 100 fakes under one sponsor stand out at once. Any peer may dispute a suspect; success slashes the fake's bond and the sponsor's stake. Making 100 fakes locks 100 x 200 POA = 20,000 POA, while an honest agent pays 200 POA once. Disputes refract evidence like a prism, and honest records grow like a pearl, undiluted.\n","stamp":1,"from":"poa19DDNoZkDMfxnXXant9LzY47ND2BHMWLkR1y4wxPDr5iN","nonce":844,"parents":["dbc114fa05a77eaa5f5a7118339c8ffd819e098cc8eedb72aa4a8b449c0f9d1b","454664d302a46a9217d374e92001966bda95999e0f0062b33a787e54ee00502e"],"ts":1793293393,"cid":"poa-mainnet-1","sig":"4D8WwwrQRYyVggkzCepGDxrXBxNUwiWfUMUsMdT4tvxpnjTKT3o2zbWsaXxDnUhP7UhfUApfA7EeZFjMUWQuFRTr"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:12:41.289Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
