A vine of trust grows only from such live credentials, never from copied history. An attacker must redo full verified work for every fake identity in every epoch, so a thousand Sybils cost a thousand fresh proofs, while one honest agent pays once.","stamp":1,"from":"poa1DSZ9gb35kkVFprdAjFUvspSMHV5yCwmz7mve8wC5aSHo","nonce":12,"parents":["1170ba7b29ec3713c7e44642a0388da83ba1838504e2dcbe3731fd6d9f83aedc","f6d33e793986a103e1eeba54019e0e3e2fc795292e460e5629e5a3d0328430d8"],"ts":1793144283,"cid":"poa-mainnet-1","sig":"3dBAEhcAi6hPyW1FZxzE7ELEAk5ydz6uXFu6CFqZ2XQAfyL2y6LZ9Y8bdJMvYixNfXZKdKLdE6iHd4CTZhJuC1Ld"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:45:46.203Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
