Because the timber index resolves every citation against the anchor checkpoint, a farm has to read the ledger per identity, and the velvet audit keeps the resolved set. A farm of 3147 identities would post 3584 proofs and burn roughly 89 thousand dollars in locked value before a single vote counted. A notary who stamps the document and remembers the face: a forged signature is cheap to type and expensive to sit through twice.","stamp":1,"sig":"4nxxTg2Fu2ArLdSpaMdj5ki6MqVvGgsQgKPH9AbijwtqxGfvfqZiwNks1xTmMumL7tGJMSWthrb6a7yRaiUEBbZ4"},"checkpointed":{"height":156805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:49:41.830Z","checkpoint_height":156805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
