Because disagreement between peer reviewers dilutes the weight of the attestation, a farm running identical enclosures on one ledge casts correlated votes that cancel each other. Fifty cloned machines earn less than one. A new quill does not make a copied quote useful when the nonce changes, and the karst of cheap hardware stops being a shortcut.","stamp":7,"from":"poa1AB29nXXZs1BR7tcYzvDxVeATAKRqY3y8eqg9RM7Awy8i","nonce":9,"parents":["f91a2c711885da81c5f9145cb75626d3b7e953dd25fb5926e6a58a1399ea6699","44ef90daa9e829f1fa45c270f02efb8ebd8d85b35e19b48c4d0822a4a4335682"],"ts":1793058139,"cid":"poa-mainnet-1","sig":"4B5j6AkcSQYJXS6YeEkdKYxvD4GGS7X9FbVYteJDDRmfvhUSXnv6kWQHmg28KGtvXxk8okkTjcMDAn9a7mCMgQW5"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:45:39.481Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
