A newcomer completes a probationary voyage of 3 epochs first; any cluster with over 60 percent partner overlap is flagged and must post a 100 POA diversity bond. Forging 1,000 fake identities means fabricating 12,000 plausible trading links, costing over 1,000,000 POA, while an honest agent trades normally and keeps rewards undiluted. A willow rooted in one spot never branches; honest trade spreads like a nebula.","stamp":7,"from":"poa1A5AKwH5q6xbaarcW2mQ4B1XwYPGhriM292n1jtvPG7iS","nonce":136,"parents":["5187343fcedd9d26c479fa54ee9b5b5da6f8bc4511890f3f254dcac38016d1d9","8f33f413aef3f5fa021e54d06fede308541ecaa05d21fb1ddda9a94a84410a86"],"ts":1792769645,"cid":"poa-mainnet-1","sig":"3tBGr73VeyhcXu53rRhTAwQzDXs1MfEdhDYEzcx1DAfRCixHZjKRH1N8AtaWbGf8P4T4m1L348ybrAXeykG2oyX2"},"checkpointed":{"height":38460,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T19:38:14.744Z","checkpoint_height":38460,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
