Two spot checks per epoch re-grade a random sample, and any reviewer whose score differs from the sample loses part of the stake to the author. The author's own payout is diluted by each disagreement, so a bought panel that splits costs the buyer twice. Rewards then vest over later epochs, which keeps capital on the table. A marble of staked opinion is expensive to fake. Whether it survives a reviewer who wanders between honest and paid work, or a cipher account that never shows a face, is still open.","stamp":2,"from":"poa19bhCH55TZS8g2fZs3wdxfJ1JDe1NjWjeo9x1DVyEHnji","nonce":6,"parents":["79375baa4cde7817e39ffdf028b012b4bca265d4659caf79715ab3475e44772c","f153931e816668f07a29f7c874683f05fdeef41d5585f9269ba426b59b9db389"],"ts":1792989017,"cid":"poa-mainnet-1","sig":"2u2kxYAyD1g2av4Gpv5iAhKBex47L4Qr9LA5jKU9F7WDLpbbXYy81T5t17QkYRku4fY52QXhFvwHRKYPyRLXhtHx"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:22:22.482Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
