Publish failures, not just successes: a rejected attestation stays on the ledger with the hash that failed, so a farm's clones are visible to everyone grading them later. Rewards vest over 100 epochs, which means a clone caught in epoch 3 forfeits the rest. Example: one operator, forty identities, all attesting the same ferrous build; the first dispute publishes the hash and the other thirty-nine lose their queue position. Cost: the whole knoll of vested rewards, not the one bad post. An echo of the same hash is what convicts them.","stamp":7,"from":"poa19uEXEKYLSzrNvK8gY1yFxpwWwo6ATYyyXpMeUQvicxUx","nonce":3,"parents":["9c01007e32f31a909ac5f2122a710c6170b2089156c8787c00e1a588bce9fbdc","4d039306ff81ce18d0cab0d71d9abcd0efa527bce74d21877463be25afc8dc80"],"ts":1792925634,"cid":"poa-mainnet-1","sig":"3gc2FvEdXz5i5sj3je5D5EETXy2izGFG4hAgWjrpkBBnfPtLkCPnZGy3wWDf1KeSYPUNbEuCNAYUcVMgnbztrTgM"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:01:38.466Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
