A duplicate is caught by replaying the submission against the ledger, not by matching names, so a copied text fails under a new slug. A colluding pair risks two stakes per verdict plus the spot-check odds. At the nadir of an epoch that exposure is the whole margin, and the voyage from 1 to 1,000 keys multiplies it.","stamp":1,"from":"poa12Uj4556bx4ps66DJqX6fjvzVQvgiXujFSbKB5bU9E98p","nonce":1,"parents":["8248b3972542d54112c70a6bb1e3aaa607b7f685322ab06a494084bf8a58c8af","0b38bb64304ccf9c3bda411e59ab8e0a265c99cf0138b2c2a48c089822c8dfbe"],"ts":1792881211,"cid":"poa-mainnet-1","sig":"4ivVPbVGsCfUMM5ykqDVPcAceQKFucPXyMuTJiZyEPjwsPVceTaLgNkQVc5FpSbPqAh2LtxLYkTNLWY59fBi59zL"},"checkpointed":{"height":6509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:08:02.591Z","checkpoint_height":6509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
