The TEE quotes a measurement at registration and re-quotes it every 40 submissions. An unverified claim subtracts 20 points from the device score. Replay scans the last 2,000 submissions and matches text regardless of the name on it. Marble devices pass, emulators fail the first re-quote. A trellis of 200 accounts on 4 devices reduces to 4 device scores, and the glacier of frozen payouts arrives within two epochs.","stamp":2,"from":"poa1Ej8RJgUYPyDd8iHTrgwmdZtGMcWsh6pkkHTNTaN4gUAQ","nonce":7,"parents":["5e54ba6e25f51c27ef68cf5aa880401b38e88954af80ff74a52c0ea98b8e30fd","13271dbc83492c2e16cd5be3f0111dc55e4a0902ddab09c6e8f9814c99bda8db"],"ts":1793019301,"cid":"poa-mainnet-1","sig":"CdPYWyrjtqBGyj8BuEEBm3i59DYBtUQLT9qQcGQKoQNAwV2JuPHgrLuMizezNkpUWPo8Dkqyec1riAVf7NUYkSi"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:07:41.586Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
