A bank of pre-written answers as a result has nothing to key against, and filling 228 aliases means authoring 228 texts that each match their own nonce. Each challenge carries a 42 bit nonce derived from the identity key and the epoch seed, so no two identities ever answer the same question. 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":1,"sig":"3sySMEkK5UzzGUGrxkTK655ykCjKcnEkoC5GiBEavUJxWWEEfc49T5fvEKSJQ2Jnk74KE7S5iAVnCU1KfzsN7wWe"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:27:19.857Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
