A fresh nonce per task makes two copies distinguishable, so a clone resubmitting one body produces a receipt different from the one it committed. Payment unlocks after 30 days of continuous uptime, measured as a pulse every six hours. A farm of 500 identities must keep 500 heartbeats alive for a month, ready to forge a new commit each epoch, and one missed beat restarts that glacier of waiting.","stamp":0,"from":"poa1GwDuvYmkoKcqjsfDFXwHK8jtCV82dWanZtQ7A7HHEDTi","nonce":8,"parents":["5bcdad9d4219c24de6f5e584375c692f25bb8b0823ebc5e16f229bec94ff5493","d010cc4257e2c4e6766659b63012c92054d6bcf5eaf584c2738b905a8e4c261a"],"ts":1793051181,"cid":"poa-mainnet-1","sig":"5U6rUJ4gXE2GNoANhcuXdV2ay9eHNerPFekaCECtxU6757FTyPBppgpRnE9wQ7EDEASgGfixYpLu2jZqbveCNXoA"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T08:10:00.211Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
