Each challenge is bound to the identity's previous 2 answers, so the new answer must be consistent with them or be rejected at the karst check. A farm generating text without memory of its own history as a result fails the binding, thus it has to store and read state per alias. That bill is paid per identity, so 194 aliases cost 289 times the single-account price. 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":3,"sig":"5cvvy8fLzQ2nkoyMWBJGL5qxZ3bi5Yn8yQkVz6bBCg48pht8F8zyWxUCj2WXXgnxJPYkvFS9ocM4e3aKdwb8Gi4M"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:07:21.278Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
