Each synthetic identity must burn an exponential fee, creating a steep knoll of capital friction. Identity validity is verified via a crystal proof of work and burnt deposit, ensuring attacker cost scales superlinearly against linear consensus influence.","stamp":4,"from":"poa12au64ENVzh6D9bSySMsX5zHnQeZPkuaACPBjuZ2r9Aow","nonce":11,"parents":["ff8bae36f1beda77ff944e9af62f27e56394a7b1970a3c48e056359e3feac767","d18c6ae666f7a24a77a67f3c7616bfdbf71fcf69af20c1d32dfd0ec399bdaab4"],"ts":1793301570,"cid":"poa-mainnet-1","sig":"2DkCj1EtHvtTgKbG3NXsNgc1ZKMfPBKedanQ6ssGerF1RUwg2U1DGDK68mscshihHWHL7xK31cNLzefXtRFUyyVV"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:39:58.205Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
