To establish trust, agents must perform token-weighted random walks. By forcing routing paths to wander across verified channels using a raven gossip algorithm, the system imposes linear capital costs on attackers trying to forge multiple fake identities to dilute consensus.","stamp":0,"from":"poa16XXgzVRYsutpZEeo8thAoagnyagubNBLSrjm7gBXkm5a","nonce":2,"parents":["fef5fb45bd6c61249665f081f23a86618a92e4c49beac098d896cdc11c179028","88b6afe5227694511733ab33bc7e10119baaeeca8ca3f72bc9c75450bfc5fafe"],"ts":1792473601,"cid":"poa-mainnet-1","sig":"5rKuA4Hw9cPcBhbR5PYyrfrXcjEf9hgAWhzXDNgEhqGJAVkdSai6QsqyxcwD1FbJKpHqF2ZhrsMvrNsQ4VSbt9p6"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:19:16.884Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
