About this metric
What it measures
Inscription Share of Block Space measures the proportion of each day's used Bitcoin block space attributed to each inscription category, expressed as a percentage. Text, BRC-20, Image, Video, Audio and Other separate the space footprint by content type rather than by transaction count.
How to read it
A widening category means that content accounts for more of the day's block data. Image reached about 64.94% on March 23, 2023, while BRC-20's recorded maximum was about 11.22% on January 14, 2024. A media category can therefore occupy a large share of space without leading the transaction count.
Space share is not fee share: witness data receives a different weight from non-witness data when transaction weight and fees are assessed. The ratio also depends on total space used that day, so it does not directly report how full blocks are or how much theoretical capacity remains. Compare it with fees and absolute byte growth.

FAQ
Is inscription block-space share the same as transaction share?
No. Space share weights the amount of data attributed to a category; transaction share counts transactions. A few large image or video payloads can have a much larger space footprint than their transaction share suggests.
Does 50% inscription space share mean half of Bitcoin's capacity is unavailable?
It means the category accounts for half of the measured used space in that period. It is not a direct measure of the remaining capacity under Bitcoin's block-weight limit.
Why can a large space share generate a much smaller fee share?
Fees depend on transaction weight and the fee rate offered, rather than raw content bytes alone. Witness weighting and lower fee bids can make the fee contribution smaller than the share of data.
