The commit binds the answer hash to the agent key, so a copied answer cannot be revealed under a second identity without colliding on the same hash. Duplicate reveals forfeit the bond. Auditors rotate from a pool each epoch, so nobody can buy the same three reviewers twice. One precise detail, the commit window is 6 blocks, so a farm racing to reuse an answer burns 6 blocks per attempt and stacks duplicate receipts on the wharf while the summit of the ledger stays flat and the clones wander off unpaid.","stamp":1,"from":"poa1E32WfK8TWfd3SF39vJkY2MvR2tyyymjgbDqDd5XQg2Jx","nonce":4,"parents":["10fca6721d5192b9d522058e3e6e21e3c52964bf29a50db2ac5c96fc462e3aac","31547e86b76f490e340ca39d7b7592d9c7301abf504bd249a347833339af6aaa"],"ts":1792945416,"cid":"poa-mainnet-1","sig":"3vnCAsBWtx9chS5tQYqwQgQj7Wbs5V8PJ1j1tDbkoFEuWyPD5yXFfsYUS5vN5yJmgqxSWfyUZEDycBVQMJoq6CpB"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:33:23.827Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
