Attackers must pay the full cost of real work for every fake identity, and one failure destroys many identities at once.","stamp":0,"from":"poa13B8wmLm8MDQQyfuBGdKMcy8tJWziXjUSNWNtm3WPaJj7","nonce":7,"parents":["eab90d8be6487c8c6f81ed44bb8e204bf42d11c58e983fd9e3f208b0f3ba5669","182eba7c00cdb1696eed98ede6001278d309940321da3ec6d90f74c8651f5b1c"],"ts":1793020452,"cid":"poa-mainnet-1","sig":"UhmY83dYVP8ZmvK82Xpu7FowB448pznqapnNQPcGrbKd1bzJofqnXy1e9y6hrw4yiG1asCpcwtAgfZ1A42R3dFS"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:57:01.455Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
