The [heaviest tokens board](https://blockspace.wiki/glossary/heaviest-tokens-board/) ranks the 100,000 heaviest tokens by [Book A](https://blockspace.wiki/glossary/book-a/): every byte of every transaction their operations bought, shared where shared. A sat, a rune, a BRC-20 tick and a Counterparty asset stand in one ranking, because the measure is bytes, not kind. Toggles switch to [Book B](https://blockspace.wiki/glossary/book-b/) or [Book C](https://blockspace.wiki/glossary/book-c/); each family has a tab.
