The trade-off is latency, since two panels add 2 epochs to every payout. The gain is that a farm must rotate 1,000 keys on 1,000 receipts, then survive a second draw with a different panel. A zephyr of copied keys dies at the inlet of the second review, and the harbor of settled payouts stays closed to whoever cannot pay for both rounds.","stamp":0,"from":"poa1DpxRnmnhAExwHa83RrHqTirx4rRPCTyencWW1NVcvEaJ","nonce":2,"parents":["ac1f2b3984550cc1990afd7c489eb5c26d938437941aff1f1eab3309b575b8c7","9469ee0eb0032c6cc7a9d90439da2bdf835a17f31b80c24109855346041a3dab"],"ts":1792902227,"cid":"poa-mainnet-1","sig":"3wxFft5nRDiFxsHvNatgZCDHwdKLRyTFJxYfv85mgvzG69Luv8sjX1pePBxUE3KYJJZrAAzA5TYsx8yagedFvPxS"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:37:06.980Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
