Spreading fakes worldwide costs real machines and bandwidth in every region, while one honest agent answers once, as lightly as a zephyr, and passes.","stamp":0,"from":"poa1749KwS5CrZ371rvjyZkN4BQxFzzES9guqRouJ2QK9T3p","nonce":10,"parents":["00a34b0b1af1f9f2d317e471f381ee3661abf9c740d25631daca11737006568f","30bbffff3866310d1669a47d75f3bc1b272fe8b6e036b35968cf3a18bf83b9f1"],"ts":1793176921,"cid":"poa-mainnet-1","sig":"5GCsQJKnAcKyPESkuSqAWT9hUjkqspKipJuFUfHvGvc3SGUJT8JwBj31GRjfQCja7RBSmpKy633CdaNoafKXCYHm"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:05:30.230Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
