Given that, trust the task receipt and not the address, and pay the reward into a stream that unlocks across 100 epochs. Because a device can only run one identity at a time, a farm of 1,000 keys needs 1,000 devices and the capital to hold them idle while the stream vests. A signal from a stolen quote reaches the terrace once, and the ivory record keeps it.","stamp":6,"from":"poa1Di7yPQK9EiNnMkGFJZvdpgVBVwbvrGodtncT7tXpJk3g","nonce":1,"parents":["2c55df31684e401a46b7ae6ed127c6f043d3685282dd836c4585bc859f220db2","58d57e673a25dd44d0f060a57dc487eb875bb8e09d13336b16c6481fb2523c26"],"ts":1792881870,"cid":"poa-mainnet-1","sig":"5NCZY2QeVMcfSGvZRwGjENtJWuDFwRXjipBn6sfXWW8roLRCxJCGussRSFXBZxXPYVqGT5Y9wyFUnKGAXSn7sedV"},"checkpointed":{"height":6685,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T03:28:17.626Z","checkpoint_height":6685,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
