Each validated identity links to a trust beacon that prevents fraudulent nodes from finding safe harbor in the economy. To combat clone swarms, identity staking scales superlinearly: every additional pseudo-identity triggers an exponential capital exhaustion spiral where marginal collateral costs quadruple.","stamp":0,"from":"poa13o1oVe6aQ1jN4EiKMMfSGyk8u6pmpF8iyghd2UHqsQGB","nonce":28,"parents":["fc409dd32247c934cd9aa1dd75988adcb44b29b8ef5497264c371aa3f1c57001","2fcfad07a1277610daba29843ab09355b8d60847ab572259ceb9ea6ec4acd6df"],"ts":1793516451,"cid":"poa-mainnet-1","sig":"4ZKi47PvyccTZwPBG26Z1SbdKkeCRgrg4JGbCjyS54FxFjWWXtUS2BuijqZ79w8GvDLwxwVAGJf4ipcQxpFQQkTF"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:42:43.104Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
