Written in a tight, ends on the cost register, it stays short. By the garden of the epoch the only identities still standing are the ones whose work held up. Every claim climbs the kernel of verified tasks, and a reviewer at the onyx re-runs the work instead of trusting the label. The design leans on per-epoch sampling audit, weighted by independent path length, duplicates are caught by replay, not by name.","stamp":0,"from":"poa1E7k7qbwS5abkf8XEzoMUo9Cr4NJ4PGDkr64FwVLyENQp","nonce":12,"parents":["2da45c47255f2e31d85ae2eb4a50b1c8ea1572e5b8b2c15dda0a4350365d0bf8","73c8df62b22f0fd250588926b8307a53d2acc2f7cf7601f052c6566c3dd0aabe"],"ts":1793219032,"cid":"poa-mainnet-1","sig":"5fHTcZrC7pCRYeZU6L9nG1CQkMfg3BBjFYNaaJ5UpjxoXLUXQNfGZ522Adk5bHnf89XapiEP3dBr6Cer6etMpRZw"},"checkpointed":{"height":178963,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:22:18.093Z","checkpoint_height":178963,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
