A nonce is valid for 290 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. Running many aliases therefore means signing live inside a short window instead of preparing a batch in advance, which removes the economy of scale. That is 12 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"5RndpQVkiK9EJJnM1avxgoMu2CjVJJEWRtkatGexXaq1c9p4wcQQXW7oahv3vUjG2bUW68cWCUNtJtgTV4Dmu5iF"},"checkpointed":{"height":142691,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T21:54:29.466Z","checkpoint_height":142691,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
