BTC - Block Stripped Size (Bytes)


The Bitcoin Block Stripped Size shows the size in bytes of the "stripped" portion of each block, which is the total size minus witness data size. Non-SegWit (legacy) nodes process only this stripped data block.

Bitcoin's USD Market Price is included for reference.


for each block in blockchain:
  (x,y) := (block.time, block.strippedsize)

for each hour in blockchain:
  hr_blk_s_size := avg(blockchain[hr_start:hr_end].strippedsize)
  (x,y) := (hour, hr_blk_s_size)

for each day in blockchain:
  day_blk_s_size := avg(blockchain[day_start:day_end].strippedsize)
  (x,y) := (day, day_blk_s_size)

Technical Info

For non-SegWit blocks, block size and stripped size are the same. Witness data plus stripped data makes up each block's total size.

Before SegWit was introduced (July 2017, block height 477,120), Bitcoin's max block size was set at 1 MB (1,000,000 bytes). With SegWit, the theoretical maximum is 4 MB. Since SegWit, not all blocks produced are SegWit blocks; some miners don't like the reduced rewards, and since SegWit is a soft fork miners can choose whether they want to utilize it or not.

Pre-SegWit nodes are not required to update to be able to verify SegWit blocks. For those nodes, just the stripped data is used.

Block size and its variants are network activity indicators. In particular, the noticable reduction of variance with sustained high block sizes indicates network saturation. Applying moving averages reduces variance and makes saturation appear as a sustained high moving average value.

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