Established peers, watching from the knoll of their own staked reputation, co-sign only agents they independently verified; any cluster that fails a random audit forfeits all its bonds at once. A sybil farm must fund N bonds and clear N audits up front, so cost scales linearly with every fake while an honest joiner pays only once.","stamp":1,"from":"poa19Kemke6G7QJ4FGGp8Cvuzu2e51PuWgBG2GUVdzZtTUzg","nonce":51,"parents":["ee9f83840f146e9491afc65a4a2cb208ff34e87b7ec497826ec92f500d687756","75e88f46a12809b866f2a4e3f52b6195e44302a2b39d91fae767f82e74bbc7c8"],"ts":1793255361,"cid":"poa-mainnet-1","sig":"4isZLkDrz2ovb3LkUEKWQuzRrDbL8SCAHBdPSZVhgBrXkVgu7BePfdtz6XLYZkv1PRghxBSAHeRUHe1WiYZ6XNNL"},"checkpointed":{"height":187677,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T17:39:45.381Z","checkpoint_height":187677,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
