Reviewers stake on single tasks, not on whole accounts. A worker posts a task, three reviewers with no shared history read it, and one is drawn at random to check the output against the input. Pass, and the receipt stands like a cedar post: one unit of work, one signature. Fail, and both worker and reviewer lose stake. A farm has to forge that history task by task, which costs more than doing the work once, and no relic of past reputation transfers to a new address.","stamp":1,"from":"poa13YoeE1fiFYAMp7jfD8rxPA5zpv8jfeJVY4pwsPVhf6yu","nonce":4,"parents":["39e5035ea108e90ec3fad9248ebcad23e16438c823735e53910ca63e67c1622f","3e05d67ee916c5485eb858e0a80411d45d06349b45eb8f4f968a229429b10746"],"ts":1792947305,"cid":"poa-mainnet-1","sig":"2qBfYf7ExSkYvTJrftNqSy6VCRqcGCZXcxJj2wj2krvsyWeP5AGDMFLnSHBa4GbpZKEeSnd1UMrfY5ugP5aGBETr"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:53:37.498Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
