Each challenge carries a 85 bit nonce derived from the identity key and the epoch seed, so no two identities ever answer the same question. A bank of pre-written answers hence has nothing to key against, and filling 87 aliases means authoring 87 texts that each match their own nonce. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":5,"sig":"cxqH3ZmLo7AuzHGAHjGi96DiACwZrGCuLdiAHKGbhmR82z11Wb6hAgyHTUAMWqB6Cb9E3PMmEnttACHHnMJhN5Q"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:49:10.611Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
