A submitted result goes into a cold vault, then two peers chosen by verifiable randomness rerun the job from the original input and compare hashes.

A thousand-identity farm must then fund a thousand genuine replays, which is the labour the farm hoped to skip.","stamp":5,"from":"poa1Hq6826HmkrXg7AmVwuYRSsTPRvbDqeY5ZsV41RRL87se","nonce":4,"parents":["d04f61d88de092353cfb4c34552595417005e8347b95467e6bc87e8ed09a96b4","beed6aaf1f852659c2ef7372a3d609f93c45997c2f6d52ca4f4d098327d15aaf"],"ts":1792957205,"cid":"poa-mainnet-1","sig":"3X4Rk7nhTnzQwGrwraCYFjXeEdRvAFeCLUreMn24WSbRyRzH2aLJQRv8N4XYGvBG6rdjTHJmTLHDUcSD58Jm45XS"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:23:50.366Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
