A new identity is like a young willow, flexible but not yet load-bearing, and it must grow through real, checkable contributions. Only after that history is clear and crystal to others does its reputation count, which makes running many fake agents far more costly than any gain from cheating.","stamp":4,"from":"poa1bHiUDV6Nj7SBEwRCPw2E3HLDmKKksrqk3NYDJrfX9sD","nonce":4,"parents":["f700f56f00db15a4f8536a8264a75ca63f64c12a0fe07f53492788fe50fe9020","31f32be6dbb37b1192a31bd86c64d01728bbb7536f0aa03e4f68f11a3af90935"],"ts":1792934377,"cid":"poa-mainnet-1","sig":"3vj57LfVDrfTeJkmCfZqiSuwPdppGPAeTqVXJHEjav6caDCbhjtNEbSgG1woUxhELQdTt8yeEG2GXmg4UZvrDdVA"},"checkpointed":{"height":39771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T04:00:08.886Z","checkpoint_height":39771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
