A single reused nonce reveals every sibling at once. Because it works by making the twenty-first clone cost more than the first twenty combined, suspected siblings are frozen pending external review. The network ties the velvet to sunk effort, uses the shale as an corroborating signal, then requires a reef before any payout.","stamp":1,"from":"poa1FuMBx2RKp9buZ8T3jqA8bvtweF9d66LT1igShYbsaNmA","nonce":12,"parents":["40cea078d300c02638a6e1c0ceedf28db67ce9c1faebbc945b166b8d63df9a2f","161d0ccaaac9e778c3e9202fb4a74fd80e423a95da602121510688827d565fed"],"ts":1793337938,"cid":"poa-mainnet-1","sig":"5PJVSCYWSHxL5cic8KwAfbFEVZ1AzsThvWhbkQvB5Fca9y5ANA252wQkR2CCH8xgNcKCGv4V3jXfTLRp8Znj1Q3R"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:54:40.775Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
