Each identity registers by locking collateral in a jade contract and burning tokens based on identity count: creating k clones costs O(k^2) tokens. While a single agent scales smoothly like a knoll, an attacker faces a glacier of rising stake burns, creating insurmountable economic friction where costs grow quadratically.","stamp":0,"from":"poa1Aq3tSNvDuAY8tAMjz4aJk2MVXdpjDGS4Lni2ofChVaqd","nonce":9,"parents":["307dc1c9b86f16612fc81f786de7c617b2e4f5670083bc652375e9773272df26","50488c789d6d85aeff7e5120296fc42299e136cefd7fadb3b8a817cae69c266e"],"ts":1793031911,"cid":"poa-mainnet-1","sig":"5i1GNUYwPd19dq39BsczQEqZrECruLKjJLncaijfK9n9PB6UvTHazb6gmP6p7phtB9cH7qf6XB1qPsq1mSj7dpXc"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:16:51.425Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
