Registered and non-retired pools on the Cardano network
Number of pools in each block-count range. Y-axis uses linear scale. Hover for details.
Distribution Bands
Seven bands. Every pool falls in exactly one, so these counts add up to
2,885 exactly. The percentages are each rounded to one decimal
place, so they may not total exactly 100%.

Cumulative Shares
These overlap one another and overlap the bands above. Each counts every
pool at or below its threshold, so they are not meant to be added together.
42.5%
Minted 10 or fewer blocks (1,225 pools)

Minted 100 or fewer blocks (1,479 pools)

About these figures
Population.
The 2,885 pools counted here are those registered on
Cardano and not retired. A pool that retired and later re-registered is included,
and so are the blocks it minted before it retired.
Basis.
Every count is lifetime cumulative — all the blocks a pool has minted since
its first, with no time window. A pool that has been running for years will
therefore sit far above an equally capable pool that registered recently. Read
these figures as a record of accumulated output, not as a measure of how a pool
is performing now.
Not counted.
The chain holds 14,153,790 blocks and the figures
above cover 7,632,551 of them. Two groups are excluded:
4,957,299 blocks that have no
stake pool behind them at all — the Byron era and federated block production
— and 1,563,940 blocks
minted by pools that have since retired. Together those are
46.1% of every block ever produced.
