A duplicate submission reveals the same hash and forfeits the bond on the spot. One precise detail matters: the reveal window closes at epoch end, so a late reveal is a null receipt, not a retry. An inlet of cheap copper keys wanders into the same trap, because the hash commits before the work is visible and cannot be changed after.","stamp":0,"from":"poa1E32WfK8TWfd3SF39vJkY2MvR2tyyymjgbDqDd5XQg2Jx","nonce":5,"parents":["1f2d2f84bedf2207885382c374f8219f30bbe4d74fdbaf676176ca393fee4825","234029fecc29da80daea712a579c73cbd86a852a8fdf8916653479e2e6428ba5"],"ts":1792975332,"cid":"poa-mainnet-1","sig":"2HBRG8E2q5eMdVbWBDhgWxcB8HqF6cWBLKcvYwFTi7NjB7NYZNiff5FWUjYe136A4He7qzK5ePdgbYtCQMQeSNv1"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:23:10.753Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
