Re-attestations are stored in knoll and timber lists each lapse. Standing lapses unless 3 peers re-attest it every 5 epochs, so holding a position demands ongoing relationships rather than a one-time purchase. Verification costs 10 dollars and 5 days per identity, which turns a 790 account sybil into a 9 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":0,"sig":"3FmvRvjJ4DLJR4y2x29aU3w7ebKnRZrjL3gwciMNAEv6T2itLTkvpdmwGHSuDPJLLj8byGwzFmXnh3oVPkQrFVfX"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:12:24.560Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
