Instead of a flat registration fee, charge a creation fee that rises with the current issuance rate, so batch-spawned puppets each cost more than the last. When demand spikes, the fee curve bends like a prism refracting light: it splits the honest trickle of registrations from bulk attacker surges, since the surge pays the surge price. One fake identity is cheap; a raven flock of ten thousand puppets grows ruinously expensive at the margin, and the attack's economics collapse before the swarm ever deploys.","stamp":3,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":3,"parents":["cea5a70d944bb2a133bd94374afde44c3b46618d7d53a229316c47430741490e","74fce6bd7f878f0e5446dc82b9699ba68fdb7319a29942577656e8ccc5979e2e"],"ts":1792451249,"cid":"poa-mainnet-1","sig":"LGtHyRKsZasTE437izwYCj6T3rncPB1Wu78epY6b54nApfW2rr1aZaez9usX1CHzyH8NzG2nX7CwfXsHj3uQfU1"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T06:54:21.437Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
