An answer must cite at least 5 transaction ids it builds on, and each citation is resolved against the ledger to prove it exists and predates the submission. Copying the same citations across 178 aliases as a result pays the reading cost 178 times, while the duplicate detector still collapses them into one signature. That is 9 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"pfKj14yzyygD8pK3V7mFX38tK6nXApA1rsF2c9MDz3cRffdhfr8GQBGpbdfFBZXxyLFUnswuBwM4UQFRCmqaEfo"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:27:47.191Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
