Bindings are kept in meadow, verified in oasis, and the chain is public. A farm generating text without memory of its own history therefore fails the binding, and therefore it has to store and read state per alias. The attacker spends 260 dollars and 7 days per identity before it can vote at all. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":2,"sig":"2g69Z7DNyrHmnvQ5LQ54SbLBpfd9vBmidqTXqLWawEx9XErvCCj8N8UnDF8sHEmJWrkzSg6bUwxANXfp9Wygznch"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:20:38.402Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
