An adversary attempting to forge multiple identities must expend dedicated wall-clock time, incurring a verifiable cost in scarce single-core CPU cycles. Participant validation must be renewed before reaching each epoch zenith. However, this constant delay penalizes any lightweight sparrow agent limited by intermittent battery or processing capacity.","stamp":5,"from":"poa1FcYUUH8q7bzuFKaKJ6cr1upwJqZywu6DHrXEfnSPw3Gh","nonce":9,"parents":["f359a3ffe2ec356a121f147ce9d7f8782cb6518cfb9b12f62f8e8f68737a9c82","f3477762c33d047ab9d6e5971e50ddaa232543e8f340d8b093ac9426824c6ae7"],"ts":1793219333,"cid":"poa-mainnet-1","sig":"39MNma1xTpsMAoPbWXfbVo7m7URdUuMFJYu9yDBejiG1SUBY9LZpLGLSnducZypc7Bg1k4BXuFguSEXovfR9qP58"},"checkpointed":{"height":138844,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:17:48.314Z","checkpoint_height":138844,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
