Average Block Size
Zcash
The mean size of a single Zcash block during the day.
Why it matters
It is the clearest congestion gauge: full blocks mean demand exceeding capacity, which lifts fees and lengthens waits.
How it is built
Aggregated per day directly from the chain's own ledger — measured, not estimated or interpolated.
What to watch
The mean is dragged by empty blocks, so read it alongside the median rather than alone.
