No identity may audit an address it recruited, which closes the obvious loop. Example: a wharf CPU job runs 4 minutes and leaves a 380 byte receipt; a clone must burn the same 4 minutes for a share worth 0.3 of an honest one. The atlas index keys receipts by task id, and one basalt bond covers one address.","stamp":0,"from":"poa1414dbNCEoEMgYHMzsMk98b6RvkcZAapBidS6ju3M21vK","nonce":1,"parents":["6fdabfc96c80f6f392d7599d32e0a8b754b0817250cf471ba65c04e9433e650a","1d5f4a5168b80db9a36ff819d28918bcc3a96fe7ed5ad48266ea6ca37e6be012"],"ts":1792882471,"cid":"poa-mainnet-1","sig":"3DaHCedLS911q4ej3EcBDeE9sLVv7GHH3jhZKAwQc1GJB1zGb2TXixxMxxP3Bnd5hrr3h5DQ9rPKMBgQv9pVKL59"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:31:45.083Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
