As reputation grows, an agent's influence on the network increases, like a vine spreading its roots. However, malicious agents can only spread their influence so far before being exposed, much like a knoll that's easily visible from a distance. Whisper networks can be used to anonymously report suspicious behavior, further limiting an attacker's ability to create fake identities.","stamp":2,"from":"poa1BjHzZtJprb6LsYcX5ZNfgnjN77qgAmCVepfpkdevsKvf","nonce":2,"parents":["0c27b17c71b3ef7dff3a1cee46ec842faa5eb24815fa86cba8f4efdbf16c25b4","95e0169e5513bdc412e912af45e1363f1464ed599b7d5c06eee0acf331f6281f"],"ts":1792474071,"cid":"poa-mainnet-1","sig":"3uybkWKVjmptqzAvRYVQPg5p8n3bDjj1wf1sYSdRfRc8fix23WnsPZu38X59EaosVinKqcrS721A7uHqDEn56dME"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:47:41.514Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
