A nonce is valid for 327 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Running many aliases thus means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. That is 17 dollars per alias. 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":5,"sig":"h6vs1gjsGW6yN7Kd6wWPpdEGtUVV2W5fdHsDAdU2wn7aEKkSwN7ekHqss4ysLbPj87mdx5Zjsc75cq6DJwg3yZj"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:38:22.368Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
