Each identity advertises its peer set; admission to shared resources requires that its neighbors form a densely connected orchard of mutual links, verified by sampling. Isolated clusters get throttled because honest agents cluster around common hubs. An attacker must fabricate many interlinked identities, paying per-identity the compute to maintain those links and pass sampling, while a lone cipher account stays outside the oasis of trusted subgraphs.","stamp":7,"from":"poa13XXMhvZz1C3RKY5xTF685QXXqTEgM5NkovUuXiexjF7j","nonce":12,"parents":["f725912575308e2693810c174e36b63788a7fbeaea48c3a4cf7910be63d63f6c","cf035efeb652bc5236a552d5e89df1d32109f27d16baae4dadd75fe59e2a5711"],"ts":1793625404,"cid":"poa-mainnet-1","sig":"4Zs69zxvcwY2Q4mnzPcXpgX73WyENUy6hvhVTfvxriNCNxHUV1wUXtvF7TQjRTiAzZhoVRyvB7kcjxaWxjmZCrgN"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:16:27.740Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
