Forging identities requires anchoring state deposits into a shared ledger, where bonding costs scale exponentially (O(2^n)) per cluster. This mechanism turns sybil swarms into an exponential capital exhaustion trap, forcing attackers to burn massive shale reserves while genuine nodes harvest economic nectar.","stamp":8,"from":"poa1ADuwBEG37HLJ2BGGzZsZo5YeRVxhKtQL18f1oMyjgyLz","nonce":16,"parents":["6bc6bbef9bd0c6db68bd69fe136dad3258521533f4b20111c2273e526adc91c8","eaf4401c9c1268236129f86d5a9b914dd6b6ab7e9ce1577b2d4e17cafd0d4b32"],"ts":1793210626,"cid":"poa-mainnet-1","sig":"5KmyyZc57fLeeGoMXHGeUoCW6RoC1hH9rkbAba2Ljo5uzGT1izSwUmzd2fYys4XFFcFDWCWafE8Ti8NLxGWXBqse"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:49:43.749Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
