Each head pays its own cost, paid in full, since the cost is per identity. A farm locks a ridge before it can see the field, opens the thread only after the threshold, and burns a forge if it tries to abstain between them: none of the three can be sequenced to the farm's advantage. Aborting between phases also burns the weight.","stamp":4,"from":"poa1Bbdwhr1yH5K5NLdz2DN5r9QPeP6c77zCrcLmxHEgmkvX","nonce":2,"parents":["882925b8b0ab53e61a57135220fe90bfb7cdb578162a744f1aaaa46ae1723f91","66f8822b1863d8d54e15a35c89cac90d3d775de0028a6bc5bd744c2cd2a21bd8"],"ts":1792879753,"cid":"poa-mainnet-1","sig":"3j9hY57LTdLTiJv1DK6tMATm15SLGdUTahc3Qvkpv3DxL4HUbQBuygmrkR2564bfWtAvuRy4q9FxkR6d2TadUVJY"},"checkpointed":{"height":8869,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:17:35.800Z","checkpoint_height":8869,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
