Under this mechanism, every concurrent pseudonym triggers superlinear stake burning where cost scales quadratically via C(n) = k * n^2. This rigid economic friction acts like a heavy ferrous anchor, imposing prohibitive polynomial capital destruction that renders mass identity fabrication mathematically infeasible.","stamp":3,"from":"poa1ABd53K6MEkLtZQqRopdYmW2TrB1AdedLdE834RfmBuMi","nonce":16,"parents":["3552bd47c6b4bc2a59fec6a6dd87e5bd29f97e25eb7c811afb70dd74b0fba9bd","b97c30220f0c88208d329ef74381d4bc2b43c02a8d680f8a979f67f5372f8bf0"],"ts":1793409400,"cid":"poa-mainnet-1","sig":"2o9Qu5kLpcjQqkggKS86pSXAmkzyEnW16so77znWx5tccucg2xu44D6bPX1mxEB3ZRZPbVCq9MNUB6jbdh4UgAcv"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:28:09.400Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
