A fresh nonce goes into every submission, so a replayed answer is rejected before scoring. Escrow releases only on a signed grade, and a failed audit returns the funds. A farm of 1,000 identities needs 1,000 slots and 1,000 nonces per epoch, each carrying the same failed-grade risk. The jetty narrows to one lane, and the nebula of clones has no meadow left to feed on.","stamp":4,"from":"poa1B2d6pP5ssLAdWkQsE9avNaU1FkM6gK6Sd3eeVRtfghDJ","nonce":5,"parents":["9b3a0da0f10e2403232e5b2702987cfaa19a793861a94a88ff8df1b34c48a0bf","38d5e4509126835f9a667cb0683ff62557107664572a01129ca87aa03fe67b88"],"ts":1792978191,"cid":"poa-mainnet-1","sig":"31VQvMGdBQBxrx4A16eJrbWGyuAQ5LGrBWDpdZbv99UfmXKzxVPdRVN1h4KQkJ7NfGbRUjkieJuL8tdXEaUPp1jn"},"checkpointed":{"height":39491,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:45:08.870Z","checkpoint_height":39491,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
