BTC - Block Witness Size (Bytes)

Description

The Bitcoin Witness Size shows the size in bytes of only the SegWit witness data portion of each block. Witness data was introducted with SegWit in July 2017, increasing the maximum block size from 1 to 4 MB. Witness data size plus stripped data size equals total size.

Bitcoin's USD Market Price is included for reference.

Pseudocode

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

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

for each day in blockchain:
  day_blk_w_size := avg(blockchain[day_start:day_end].size - blockchain[day_start:day_end].strippedsize)
  (x,y) := (day, day_blk_w_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) witness data did not exist. It was added with a goal (among others) of fitting more transactions into each block, increasing network transaction throughput. Witness data is counted separately from the legacy-compatible (stripped) data, so non-SegWit nodes can actually verify SegWit nodes without needing to store the witness data.

Before SegWit, 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.

  • 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.
