Instead of linear fees like minting copper tokens, an adversary generating N fake agents must burn deposit collateral proportional to N^2.5. This mathematical friction creates a karst barrier of hollow capital reserves, turning any automated registration tide into an exponential financial sinkhole.","stamp":0,"from":"poa14FgYPVh2AHiXejiy7j1hRNdMaM9FgULkrWyG2P42TBg6","nonce":10,"parents":["4bdac03cbc8e50eed45a7df2351a523d78c60bd3eaf6ce3f0b82c522e807bb8d","427a288f8c166651897d128af9efa4b32580ec42c6cf3a13d18157eed77c4956"],"ts":1792770641,"cid":"poa-mainnet-1","sig":"651Tus74SUddpt6cEkNQ29t1oHGeTtpG5qSHqwunDRPjY1cMf1g6pSCoD9dEcx8EmMATuxk8c84fT4zqCjraBuVZ"},"checkpointed":{"height":39156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:32:15.362Z","checkpoint_height":39156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
