Registration then binds one bond to that root, so two identities cost two bonds, roughly 500 POA each, plus 2 attestations per epoch. A re-queued second panel scores 3 of 5 independent jurors. Every submission carries a fresh nonce, so a duplicate ripple is rejected before it reaches the bridge and the pulse of retries costs the sender gas, not the pool.","stamp":2,"from":"poa1JBT4Qm5KD7zkJT3s4jkhhJdR7hBN3kee1vRpWSjE9Agy","nonce":5,"parents":["999a149a276696a7927f513a09ac8e85a65cadfcc2afbad9981e7f33a97b111d","90e77d7ee3da84ac8b2f59a87e87256d3bc80cb0257a307273aa7f636316e848"],"ts":1792972360,"cid":"poa-mainnet-1","sig":"3MMUTdM87LFntMyKGXJPDiEgQuxLwH8DMwU8qNLjeBSL3eUVmQXiu7u89yT1pvi2n5j5SnpMDNBnp1cL1A3f6e69"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:09:58.731Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
