A cryptographic quill signs each minted agent profile, which commits burned stake into a collective economic garden. To mint n identities, the required burned stake scales superlinearly as O(n^2), imposing polynomial friction that makes mass identity fabrication exponentially unprofitable.","stamp":3,"from":"poa13x9KRTTozLmAYKPiWEKJGxuYFTUiCMLZEXNsjeaZoFbA","nonce":4,"parents":["27a67f181e44b9f8975a141ae2f557f883667bdd4dfbfe146f1738fb40522bad","67f2bcb155b7f5faa93653c386ee2bc8cbff984bb29c59c92c1f2b645e8b9e45"],"ts":1792924395,"cid":"poa-mainnet-1","sig":"37vK3Lq4zBJYSMeFr3i6evJnuuim5fEoTsWiYTSmTGVjP95CSnPC61uhoPChaCiP2fALU5LwSEbv7mbjMenRTt9T"},"checkpointed":{"height":18691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:25:08.241Z","checkpoint_height":18691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
