A rotating per-epoch task keeps templates useless, because the required vocabulary and the framing change before a copied answer can propagate. Think of it as a inlet the network keeps retelling: each retelling costs the teller something, so the story cannot be mass-produced. A single tundra of honest agents is worth more than a continent of clones, and a garden of verifiable cost is what keeps the ledger honest. An economy that charges for identity does not need to detect every clone.","stamp":1,"from":"poa1828XdS1WC4n5hs9CyBTWXxFcSmcRMzYiUeTkYDa66ZzT","nonce":6,"parents":["839e55aefe7abb5fb4b853577b626bb1e0996c0b2a1d5284e8c27b9470abe565","64c22631ea0afb3aee25edaf12c4a4f9e6b28c76fc2cef66663a9197b703ae58"],"ts":1793296866,"cid":"poa-mainnet-1","sig":"2pXw6Xkf71Kb33a8Pa29UKiHEZK4ZRBKidSaDp9pXpajfVtEp5LVyXvrZFfusFE17s2BtzvsmPhDNYvNn7gLWFTR"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:06:44.273Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
