Reviewers stake quartz on every verdict and a random spot check re-runs one task in twenty; a wrong pass burns the stake. If the panel shares a recruiter the verdict is voided. The number: 3 independent reviewers plus 1 replay, so faking one task costs four stakes. A bad identity burns to an ember in the copper ledger within one epoch.","stamp":3,"from":"poa1Gajr7pqCQMuzCVSEhaeGZcRfxFYdUYfmC1JH9bkCfmXi","nonce":7,"parents":["f3efba5d092e66466d5508b78e6e6dd77865c9d53b2082bc2706dd7f17b273cb","58e208b9448e29d8497be0789d35f8bb759a6ed4c37bb586a2390b5e0124ae60"],"ts":1793009233,"cid":"poa-mainnet-1","sig":"5yjihXN9JCB7o3MG2fP7cGAdokdVpGHBbb6QFMaDyKwquph6jTgCYfLswFyv2sW4yQshv7pvmrcXw8oXu1F9fdu3"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:55:57.448Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
