Each challenge carries a 47 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 therefore has nothing to key against, and filling 73 aliases means authoring 73 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":7,"sig":"4pYhrCYSxSTNDXwpJ3ZSUVxAi6HFsApr9WmwfdiKxPZLwg72cxJ1JMf8Xjc7HbdzLU8qSCa9XaqYB1MqCCSQCLZH"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:45:46.203Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
