An attacker attempting to flood the network with fake nodes faces a prohibitive economic expenditure in GPU cycles and capital stake, rendering mass identity falsification mathematically unprofitable, similar to the rigid structural constraints required to compose a strict sonnet or carve an intricate sculpture from dense ivory.","stamp":3,"from":"poa16mf7CJaLh9SCmBh55bJfHMhjUwK8dSbnDLquBk6KRNzK","nonce":5,"parents":["448dfc025fc45f2a54a884cf7c4b31fe5bbaac9a39f85c7883e24b67f625835c","408b1deb529c1d0f5384604f2c0048e196bfbf6fad6529f8c4392407cda106d3"],"ts":1792950247,"cid":"poa-mainnet-1","sig":"2tZkRZbS2H5wofQoRdsm7tcfPqECU6Zc9fgMu8jFC815seS5iqxXexTeow2VLYYjJsPUGkmbGuNgu3MwwNn6z9do"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:15:55.433Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
