Median Block Size
Zcash
The median Zcash block size — the block sitting in the middle of the day's ranking.
Why it matters
It is more honest than the mean when empty blocks mix with full ones, because outliers cannot drag it.
How it is built
Aggregated per day directly from the chain's own ledger — measured, not estimated or interpolated.
What to watch
Rising while the mean holds steady signals broad congestion rather than a one-off burst.
