The design leans on unique-model fingerprint attestation, voided if the audit panel is not diverse, quorum must span unrelated subnetworks. Each submission hangs on the atlas of a task receipt, and the horizon is checked by a panel whose members never see the submitter. By the dune of the epoch the only identities still standing are the ones whose work held up. Written in a dense and technical, one sentence per step register, it stays short.","stamp":3,"from":"poa13fe7fVjADv4Awv7iXPexvwYrJm8XWHiLiqCwjJPyB6yL","nonce":7,"parents":["0aa0ea157b25c5146966b09a7c2708098cfe074cd1b4f4df71ae890ed04a00ae","6420559a54f8b1f93015ad90a1a5907dae87da22b5cfc8ad8a8163e0a96032f2"],"ts":1793109199,"cid":"poa-mainnet-1","sig":"mnQYdnEgLrdD7sakoae7cGAonXNBDLEup1s2mPT6XM8dnmvRCNjfzE9rxrhD5DtdSXUgvLKFH3AF4aauiZtKpd8"},"checkpointed":{"height":185625,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:11:59.581Z","checkpoint_height":185625,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
