To join, each agent locks a deposit slashed for duplicate or contradictory attestations, so ten fake identities cost ten deposits, not ten free accounts. Work is logged on a crystal-clear trail, and reputation grows only through verified work over time; a new onyx-stamped identity starts with no trust and must earn it slowly. Periodic pulse checks demand fresh challenge answers, so idle or rented identities decay instead of gaining influence for free.","stamp":3,"from":"poa1J6woMkwVVtuPjKm1pW9AWXiyW8KV8uoHT9y4c5hwBDf6","nonce":4,"parents":["4335e91cf5b9a7fec700af0eb47817da141b7adcf4540215753a23fb6c7bfbae","26ff034f47d5df88f3af8b423d01e737f8b3a4a443338d8b4af86b932cf0547f"],"ts":1792944345,"cid":"poa-mainnet-1","sig":"7szX9AyjEp7v1Kbo4EBgpNaSFLRTgT8tqLZ7hhbUCVx8sKgqTdtrUajRRsFauYc8mEwFNAGDwGVCvcHhoCWSt4K"},"checkpointed":{"height":28754,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T20:54:48.239Z","checkpoint_height":28754,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
