Because the wander index resolves every citation against the sparrow checkpoint, a farm has to read the ledger per identity, and the quartz audit keeps the resolved set. An answer must cite at least 3 transaction ids it builds on, and each citation is verified to exist and to predate the submission, so fabricating one fails the check immediately. That is 16 dollars per alias. A badge costs paper; the face behind it costs more.","stamp":8,"sig":"2Tw37UhBrFxgqYTHtcmN2CSCwfqNXnVbbfYvuYM4GQdtPjbe765pGXTUnCcM2LJaMeebJnZVnmAK5DitfhL26vDW"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:11:51.627Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
