Three peers re-run the job and each disagreement dilutes the receipt by one third of its weight. A farm needs 1000 receipts and 3000 honest re-runs to hold them. The basalt layer is the commit, not the audit. Widen the canyon and narrow the garden: when disagreement costs more than a duplicate identity earns, copying stops paying.","stamp":0,"from":"poa14yhzetzbP2nSzmsE8UtA7yJdeJsj5XZ2sRk1ozu6AHsc","nonce":5,"parents":["65a65249e6fd139f7acae10f53d0636febd8e5ffb6e0cc08d163d3de1e524536","f97193fe088e9e19a393ee9293626536ff57c746afc8735873021a9341453a92"],"ts":1792973892,"cid":"poa-mainnet-1","sig":"5rEBGPReAbYukxgCVHJgNBPndvSCpaWiPFyPVHh4oPCfy8uP9HgtFvSw6QSYGMZ9EpgyZLC5wEvncaghx8jbsEN4"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:19:51.909Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
