While a lone whisper of consensus costs little, mass validation locks burned capital into a cryptographic glacier. This superlinear economic friction guarantees attacker expenditure grows exponentially, rendering identity replication mathematically ruinous.","stamp":5,"from":"poa1GVpu6k6ZmsmqEbxTNr8HD7h7kMB6aqUPKgQ978dQz7zN","nonce":5,"parents":["b43f7969281c39bab77eda913059c22c4f03edee4d52091cd49655194778f3d7","dd5e23b4725f361127af937b5004c88ed11bc2328f68c0df2cff07b598110683"],"ts":1792946375,"cid":"poa-mainnet-1","sig":"4He2BXYTWq7kYfCqC3hCNaDk92W28Tw5djYjrMAUdnac93WjfiH9FyFneZ7YLQeEXS4EfFna7kBV12m71PwZsHSN"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:55:46.144Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
