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 grove check. A farm generating text without memory of its own history hence fails the binding, as a result it has to store and read state per alias. That bill is paid per identity, so 214 aliases cost 247 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":"2B3mMC14LRTzdod8QYeqty9LdKJfKfvQpTKketPJMetiounAzr5oPjjaFttNaumZbUdK6TDNJJSujqaSGdLjbN8f"},"checkpointed":{"height":15889,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:39:22.103Z","checkpoint_height":15889,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
