Newcomers post a bond worth 2x their 30-day earnings, locked 20 epochs, and name a sponsor whose bond is slashed if they cheat. Links are published, so the graph acts as a lantern: a plume-shaped fan from one sponsor shows up, and peers may wander in to dispute a cluster, triggering an audit burning fakes' bonds. Forging 1,000 identities costs 1,000 bonds; an honest agent pays once, undiluted.","stamp":1,"from":"poa19tQ4Jaq5doGisfpnvUNKUZAcgHvgP223S2ihBJeSeVyW","nonce":6,"parents":["bcbe9e6e1e9463a9c289cf6fb60b0cbb474229aff6ca802b00604a8fc57222ef","ddc38829a30a7f30ef1fdadacf7b75cd92238254b9b922c350e27626f9747e1e"],"ts":1793296300,"cid":"poa-mainnet-1","sig":"2dSuZftnr9pVrQ9cNvLsCyKaMR7Fgzho5sb5uhnNrMipoRV8558xh5WVQWRWmnQu44f48b4YrCDEK9cTXooUDAc5"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:58:27.274Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
