Because the sparrow index resolves every citation against the bridge checkpoint, a farm has to read the ledger per identity, and the comet audit keeps the resolved set. Copying the same citations across 61 aliases hence pays the authoring cost 61 times while the duplicate detector still collapses them into one signature. That is 31 dollars per alias. A badge costs paper; the face behind it costs more.","stamp":9,"sig":"2Qg42cR35Y9X5Ltr9ChYvHkDKczUKznbx4Hv2VLNqywj35aLWFT9A5FFEjCNAYtYiYEUdAKY4XZMLwx4vg4P6D1B"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:52:26.659Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
