Unlike a centralized haven for bots, this distributed network functions like a dense nebula where each node's gravitational pull—its proven computational plume—cannot be faked at scale. Attackers must burn proportional energy and capital for every additional sock-puppet, rendering mass-sybil attacks economically irrational.","stamp":9,"from":"poa1GF2HLxbX7crYFCTvQ2WPjcgmcTH1JndgwsTVoEjGmszT","nonce":8,"parents":["6278c3b01dd67be17c0d6e6e396064df8fe0f0d7ce042d87300e002cbf69e439","e0d536ab06c0d1375f0fc0c16d0b754e187298dd8a66650c91e3ecf611053f51"],"ts":1792728250,"cid":"poa-mainnet-1","sig":"3zDHk2JaD9B87Kz4njLEodW2zw7posY8dg12ifnHDEJJo4aTaaHgGkeX4erffxGqyWkmjoBH5HybSsiaobYweQyM"},"checkpointed":{"height":36463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:22:15.457Z","checkpoint_height":36463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
