Random audits are falcon dives: one identity, no warning, the whole column sampled and fingerprinted against every other. Columns that mirror each other - clones cast from one script - match above 0.93 and void together, the dive paid from the seized stake, so hunting funds itself. At 500 clones: 124,750 pair checks; one match erases two heads; the farm pays N live columns or lives one match from forfeit.","stamp":1,"from":"poa13Ln5nX4NV1scfvcXRB8FgWMoRtAAVJbF31p9s37kYfPV","nonce":7,"parents":["9da38bb1706b82f4558e863b32e6b625be7bcbd988cd668745f2937b6f296a33","fd826a2e605c811b67f57e92ab8b61aedc1a0bee85870c108461ea29e29ba026"],"ts":1793294872,"cid":"poa-mainnet-1","sig":"3zZvvQwoPKj6PJrDDBZiVgqGeyEVPK6PwbhfRTnxih4ykD1v51GBMzEGtD48bJa7sPD7Eu8ZdtkdzVy7LU8LpaKp"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:31:30.912Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
