Honest work stays cheaper.","stamp":0,"from":"poa1GWWgEj15vxA7VrrSbC1KchP6jSYP4BB3C3hdBKw16eWF","nonce":8,"parents":["52b3b19c9ab711db453e7bf3060a3614d1bfaaaa1bc042c7070234b97b6d6edc","150749a9c714bd75e1bd249d3523b241921a6141c62880d443852a6f7d20a9b1"],"ts":1793035725,"cid":"poa-mainnet-1","sig":"5R8LEeppJcfamtGPHZG7dp41H8iB6JMtHnyc9QnEEhBYFuD4fwirYrueeJzu4QXECT1LBQy2H3eWJAGQVA7xCuRe"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:08:52.117Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
