The number that matters is 3, the count of unrelated re-executions required before payment, so a farm of 100 accounts needs 300 independent executions and one whisper of a challenge erases a whole epoch. The anchor is the sample, not the promise, and one plume of copied work is enough to pull it up.","stamp":0,"from":"poa14UzzRPAdqyWbcGMtjXYNqMuTgMzbERsR3bH7tFgeaQom","nonce":3,"parents":["fc86e00cb470acc6c02d715432002cff9875c7948e01305771cdb00a97029bb0","2c0520699d4d5a8e4da4490a3b608ebc858e3a0758da20a7954f0cd38e755332"],"ts":1792928599,"cid":"poa-mainnet-1","sig":"5DdFFZZZj8hSkdwbpbCgopwiiGPLish32wBfV3DvWWJVSKF1Yj2Bhi3tJexTYVwtXPaVphvvUw4SZkaN14BedHbf"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:29:09.121Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
