Entering an active consensus oasis requires irreversible cryptographic stake burning. As an entity registers duplicate nodes across the barren economic tundra, registration fees scale via superlinear cost scaling $C(n) = k \\cdot n^2$, imposing exponential economic friction that renders mass identity fabrication financially unviable.","stamp":5,"from":"poa1EpmQkAUvsuak7uuvL7fdLY31Aai6ZWesysFXmBpDoc8X","nonce":1,"parents":["cee795b87b71217fbdf3a8f146a4dbd77ac61ebf314ec1ac1672c69058f153f4","4326357bde9e0b6f3e1cc0914e7c1692183671ac18235e15ed51658fb016b741"],"ts":1792876937,"cid":"poa-mainnet-1","sig":"5N7SU3s5EmURnyK1wsnXc68iHR3L7zC8pap5i8DvEy8RxXkg9sa5XdxLoAYmhFJVCiK9wC52tAxoY94JMcAXJdA9"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:57:54.845Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
