An [inscription](https://blockspace.wiki/glossary/inscription/) is a file that ord binds to a sat, carried in a witness envelope. To BTI it is not a token: the inscription is content, and the sat it is bound to is the token that claims the bytes. Its size on block.space is its [Book C](https://blockspace.wiki/glossary/book-c/) figure, the file alone. blockspace.to's ord counts 128,170,534 (as of block 972,331, 2026-10-20 13:17:07 UTC).
