The [heaviest sats board](https://blockspace.wiki/glossary/heaviest-sats-board/) at block.space/heaviest-sats ranks the 100,000 individual sats with the most blockspace bought in their name, by [Book A](https://blockspace.wiki/glossary/book-a/) unless you switch to [Book B](https://blockspace.wiki/glossary/book-b/) or [Book C](https://blockspace.wiki/glossary/book-c/). One row is one sat, with the inscriptions it holds. Tabs narrow it to sats carrying inscriptions, BRC-20 inscriptions, bitmaps, sat names or CAT-21 sats.
