What percentage of the Monero hashrate does the biggest pool control?
There is no fixed percentage: the biggest Monero mining pool’s share changes as miners join, leave, or switch pools. To get today’s figure, you need a recent pool ranking and a matching estimate of the total network hashrate; I can’t verify that live percentage here.
How you find the percentage
A mining pool combines miners’ computing power so they can earn rewards more regularly. Hashrate means the rate at which that computing power performs mining work.
The biggest pool’s estimated share is:
Pool hashrate ÷ total Monero network hashrate × 100
For example, if a pool reports 1 unit of computing power and the network has 4 units, its estimated share is 25%. Those are example numbers, not current Monero measurements.
Check a live Monero pool-ranking service or block explorer, a tool that shows activity on the blockchain. Look for:
- The largest pool by hashrate, not by number of miners.
- Its estimated percentage of the whole network.
- When the figures were updated.
- The time window used to calculate them.
Avoid dividing by the combined hashrate of only the listed pools. That leaves out unlisted pools and independent miners, which can make the biggest pool’s percentage look too high.
Why two sources may disagree
Neither pool size nor network size is perfectly measured in real time.
A pool usually estimates its hashrate from shares, small proofs of mining work submitted by its miners. The network’s hashrate is estimated from mining difficulty—how hard it is to find a valid block—and block timing. Monero targets a block roughly every two minutes, with difficulty adjusting every block.
A ranking based on the last hour can therefore look different from one based on the last day. Mining also involves chance, so a pool may find an unusually large number of blocks without gaining more computing power.
For a useful answer, prefer a clearly dated estimate with a stated averaging window. Treat recent block share as supporting evidence, not an exact measurement of hashrate.
What “control” actually means
If a pool has an estimated 30% share, that does not mean its operator owns 30% of all Monero mining equipment. Most of that equipment may belong to independent miners who can move elsewhere.
Still, with a traditional centralized pool, the operator generally coordinates the work miners perform. A large share therefore represents meaningful influence over block production while those miners remain connected.
Decentralized pooling works differently. P2Pool, for example, lets miners cooperate without one central pool operator. Its combined hashrate should not automatically be treated as computing power controlled by a single person.
Why the percentage matters
A pool approaching half the network’s hashrate raises serious concerns about concentration.
With a sustained majority, an attacker could potentially reorganize recent blocks, block some transactions, or reverse their own recent payments. That is commonly called a 51% attack. It would not let them spend your coins without your private keys or create coins outside Monero’s rules.
Half is not a simple boundary between “safe” and “unsafe.” Large concentrations deserve attention before that point, and estimates can change quickly.
The bottom line
The biggest pool’s percentage is a live estimate, not a permanent Monero statistic. Check a current ranking, confirm it uses total network hashrate, and read the percentage alongside its timestamp and averaging window.
