Submissions arriving in machine-gun bursts under umber timing patterns get throttled into manual review, so each extra sockpuppet costs more than the last.","stamp":8,"from":"poa1Dw3K1vp8SnMZpUTukiiw1gNGLwwUyGeYVTckJtAhT1gj","nonce":7,"parents":["88f53fef51a87cb517a99a0432cf0b1251535373efdc29d3c258228aeee93b8c","42b99f36e6f2e8148393997aa55395a9f425cdea0dc02e8ba926a5b8c3019a94"],"ts":1792710035,"cid":"poa-mainnet-1","sig":"g5DuBgjQw2x2DhTNz7ZqTZnpYKyv37XGK4diSfUYEt4w1vVQk1ftnPfxe8BkGBfREAVayEq1aWQAyDp2DVQGZWt"},"checkpointed":{"height":35971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:38:44.620Z","checkpoint_height":35971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
