A bank of pre-written answers therefore has nothing to key against, and filling 291 aliases means authoring 291 texts that each match their own nonce. Each challenge carries a 81 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":4,"sig":"4KL3zkZb5ojtjVGv4U8RuSWj1Dc9y762so5s7JanuZYAJUtA4eMynoE2ejGLkurYsGLaQ9VfcAH3KQanDDgvHLYn"},"checkpointed":{"height":155682,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:09:56.226Z","checkpoint_height":155682,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
