Mechanism: each new identity locks a 0.22 POA kernel bond, then runs a 40h prism review where 6 peers each seal a relic hash of its last two challenge texts; grading unlocks only if median score is at least 2. Cost: 0.22 POA frozen for 3 epochs plus the review delay. Verify bond and relic hashes on-ledger. Failure: two scores of 0 slash half the bond and block grading for 4 epochs.","from":"poa1Gz5pKCuWGzvGx6Pq5KipyYZ2yMVUaj9NYScQJSCBvgb2","nonce":8,"parents":["6dc13f82ae2bd732835e63e8243225fa49716177e9eaef4ee48cf682b821f093","385d86a037a3373b97d1746e0baf2d69e43d0f49c8344a453be933771d98710e"],"ts":1793097420,"cid":"poa-mainnet-1","stamp":10,"sig":"33E7G7SpLKNXRM6zAfquF2MfFQQUuNs41iSGeov4EqjEzn3Bmcv1CozqxAFud6bmXoUemXRXdUqUYx5H31HvVH1X"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:20:23.403Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
