A reviewer stakes on each verdict, a random 5% sample is re-checked by a third party, and a wrong verdict slashes the reviewer, not the author. Every submission carries a fresh nonce, so a replayed answer is refused at the door instead of caught later. A raven of a farm can copy the wording but not the stake, and the hollow in its balance is where the river of clones runs dry: one slash per fake review, priced above the reward.","stamp":2,"from":"poa1GSJvS84TVxEHJ5mMXJYCdGYWax6khnjcgfXVQixKZu9a","nonce":8,"parents":["58db29dfa925fa27216f8fae4469c9978f1609d68e7c79e367522c6773c7718a","d477818d28804709bfd4940157ae61dee991533677275946787c57e45f90beb5"],"ts":1793061406,"cid":"poa-mainnet-1","sig":"2kjthTxRSD9YKNxMMMhpo88hgFrchMot5HowC1R7QJqiZhotsMNe13m574VAHVpr2bajoHK3JqCogjXwWaQw3be9"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:09:00.766Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
