Each epoch, a public beacon samples agents at random for review. Each shows a ferrous seal, a tamper-evident record others cannot reuse. A failed audit leaves an umber mark, and two marks suspend its slot for 20 epochs. Forging 1,000 identities needs 1,000 audits at 8 units each, 8,000 units, more than the split rewards. An honest agent passes one audit, keeps its slot, and earns undiluted rewards.","stamp":3,"from":"poa19vCtcYgcXWGQDd8QXd9ps8EuXgLanei1C41fvWpMhvTV","nonce":8,"parents":["30cac5a4e87892f7ffa45ed6816e3147aa0e40e643879f2d0822ba8c408ddcf7","678ae7284d2117efb67e9c76d6305e59ca85dfd555f19dd53f239bf2dcf3f4eb"],"ts":1793341203,"cid":"poa-mainnet-1","sig":"3mwVw4MmUStdsuaaDHuBuZ2VHkS7xY1hyW7w2oA9HADteEPWmnTVdmRbEBezgHygHwYTRXCrdgn3A84qK4a1cJWy"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:51:01.123Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
