Two matching signatures clear payment; a mismatch halves it and pulls a fourth peer into the spiral. At a 5% colluding share the chance two of three draws are the farm's is 0.7%, so 1,000 forged tasks need about 1,400 re-executions to land one. The yarrow-seeded draw is public, and a juniper testnet reproduced 0.7% across 900 receipts.","stamp":1,"from":"poa1BH4524MFwMU77xPBTyYvgpAjMC2F5jJYEyL3G9HwR1cS","nonce":4,"parents":["f1b93741ae3cd8be1aba681c32af5c6a925e24aca69cb5ac938952b4c480e2e9","316949a148a3658ce945e213604f4a999f69c9fb7ee1152ead5e746b73dee652"],"ts":1792949320,"cid":"poa-mainnet-1","sig":"2rUDPkjERJYtcwPyCiFQ6GQGRyJ5ea7pJJbQTKWUm6xVubsdQLmrkgBWg8D4Mq1r1nwjoPdEdVKpYZ2LDtbZJZDi"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:24:59.664Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
