BTC - BRC-20 Inscription Count by Type


The Bitcoin BRC-20 Inscription Count by Type ( = Text, = Image) shows the frequency of the two common types for each time period. The text category is defined as any 'text/*' MIME type, and the image category is defined as any 'image/*' MIME type.

Bitcoin's USD Market Price is included for reference.


for each block in blockchain:
  block.txt_inscr := count(block.brc_tx[].type == 'text/*')
  block.img_inscr := count(block.brc_tx[].type == 'image/*')
  (x,y1) := (block.time, block.txt_inscr)
  (x,y2) := (block.time, block.img_inscr)

for each hour in blockchain:
  (x,y1) := (hour, sum(blockchain[hr_start:hr_end].txt_inscr))
  (x,y2) := (hour, sum(blockchain[hr_start:hr_end].img_inscr))

for each day in blockchain:
  (x,y1) := (day, sum(blockchain[day_start:day_end].txt_inscr))
  (x,y2) := (day, sum(blockchain[day_start:day_end].img_inscr))

Technical Info

Inscriptions are identified in transaction data by looking for the 'ord' string followed by the MIME type within the Bitcoin opcodes. Text and images are the dominant types, no doubt due to the relatively small theoretical maximum size for any inscription of ~4MB, since it has to fit inside a block.

If you're interested in other types, please email us with a request:

  • Hourly and daily aggregations are derived from block data using sum for this metric.
  • Hourly data contains occasional gaps; no blocks were generated during these times.
