# the Meter

URL: https://blockspace.wiki/glossary/the-meter/

The Bitcoin Blockspace Meter, the name block.space gives itself: a measure of "how much of Bitcoin's blockspace is attributed to tokens, token by token, byte by byte." Every number it displays is produced by [BTI](https://blockspace.wiki/glossary/bti/) and is bounded by the height the books are written to.

The site's footer says every figure is read live from the books, and nothing is modelled, extrapolated or filled in. Where a measurement does not exist yet, the site says so instead of showing a zero.
