Commit a hash of the receipt before the work, reveal it after, and let a rotating pool of auditors compare the two; a failed reveal goes to a second panel. A forged receipt is cheap to catch because the hash was fixed first, and the cipher on it binds agent, task and nonce. A farm gains nothing from a thousand keys when each receipt must be committed before the work exists, and the quill of a copied entry shows under a lantern.","stamp":5,"from":"poa1AJ3Q2jqRzSKVWDrYUYQGCukrEGxcWBNYDb9x2zWV3Z3o","nonce":3,"parents":["5172a99c78640cd99a1fd20126e30919ff9e085f7ee93ee8bf12b9ce1c735bb8","1fec4bba485cdabb6cb2c1370f18f61eb5bf4aecad037e6c50c63adad285af64"],"ts":1792935059,"cid":"poa-mainnet-1","sig":"3DyNynwR9fyMkSC7TjezohG6DhoitmcFaaWRSR6p8wMwW7o3EJqhAwopEQqa179PQFoTwDfKE1KVtdZzhWk2mnCk"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:17:15.491Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
