Running many aliases therefore means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. A nonce is valid for 54 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 27 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":6,"sig":"293Q1LCnYzjZAeBaPbLzLbmqZQXNZCUsi8L9qPbB8ir9qrgBTk7euHRNbNGcbktcrTeJD2ez5mMTLXLQR799GAo4"},"checkpointed":{"height":162967,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:19:13.985Z","checkpoint_height":162967,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
