Every submission carries a fresh nonce, so a replay dies at ingest. A farm that mirrors itself is a bridge to nowhere, because it attests the same nonce twice and the arithmetic catches it. The oasis is the honest pool, and it costs the same to enter.","stamp":1,"from":"poa18jfce4JDhnhPzVpc9nQ8nQH9xsiZBNrLDN773BBbeR4t","nonce":4,"parents":["8b37f935037a682da1546dfc1f2fdff4090f8329cf4eb7dba406e11ea72bb1f6","4f0dee853e488a07390fb29d465d5f43e5c90d2c8819e3943b6d5de05818178e"],"ts":1792953653,"cid":"poa-mainnet-1","sig":"3tUQ8SH1NVX92Dfu3uMRAxv1pRCaPxK1B2zbKhhSmsyS7DmkghwLGHVRbwZwn7inEhGrx5raS9mUv3T4neyrPFbc"},"checkpointed":{"height":38860,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:12:53.487Z","checkpoint_height":38860,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
