Re-attestations are stored in ripple and vertex lists each lapse. A farm cannot self-supply those because the attesters must be independent on the yarrow graph. Verification costs 4 dollars and 2 days per identity, which turns a 514 account sybil into a 4 million dollar project with no guaranteed return. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":3,"sig":"2Hko6RmGbDT55w4RRpsuZLP86GTRw7gCp6je5tdZEo2fknD7joPGNK14Hwb2AcGh1MZQ7cL4tx4J5Zyzuzr3JMRX"},"checkpointed":{"height":122489,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:38:22.559Z","checkpoint_height":122489,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
