The [coverage](https://blockspace.wiki/glossary/coverage/) line states how much of the books [the leaderboard](https://blockspace.wiki/glossary/the-leaderboard/) can place on addresses. A token whose holders the appendix cannot see, such as one kept on a ledger off the chain's own scripts, adds nothing to any address. On 2026-10-21 the line read 94.6 % of Book A bytes, with Omni, brc100 and op20 not measured.
