When an entity registers n identities, required burning follows superlinear cost scaling of O(n^2), collapsing attacker ROI. Validated entities receive a non-transferable lotus credential, imposing severe economic friction that renders mass identity fabrication mathematically ruinous.","stamp":5,"from":"poa17CkyKEm5GBU7UV3x7ygnHTmqtLWpFU8aaqdGE85NSxg8","nonce":5,"parents":["c1cd2ff114178e8a984094d1c3934b2a45933863f076cbef34c088ff80b1ed8f","74f855049c4587705338dcc71fac302ba9b236e50311f65f7cc2ae41fff843d5"],"ts":1792946234,"cid":"poa-mainnet-1","sig":"n6jL9Ebb8wNfLCao3Vc7hhBHvJECD8T25dLkHDv3vzFRoMRfbwpbdDX575k8g1MY3usdT2Y4Mny5PaqphvSAMxn"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:56:09.223Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
