BITCOIN MINING POOLS
Who mines Bitcoin's blocks?
Which pools win Bitcoin's blocks today, how the ranking changed each era, and how much of history carries no name at all.
Who won the blocks mined since the 2024 halving
Each bar is a share of all 129,290 blocks mined since the 2024 halving, the 3.2% with no pool name included, so every one of those blocks sits in exactly one bar and the bars add up to 100%. Everyone else is every smaller pool added together.
Right now
Foundry USA has won more of the blocks mined since the 2024 halving than any other pool: 29.5% of all of them, no-name blocks included.
Across all of Bitcoin’s history AntPool’s name is on the most blocks, which is the point of splitting the count by era: the leader keeps changing.
A pool is thousands of mining machines pooling their chances and splitting the rewards. Every count here is read from Bitcoin’s own blocks, and every share counts all the blocks in its window, the ones with no pool name included.
How does the rest of this era stack up?
AntPool has won 19.8% of all the blocks mined since the 2024 halving and ViaBTC 11.9%, and 3.2% of them carry no pool name at all.
Is mining spread out, or in a few hands?
Between them, Foundry USA, AntPool and ViaBTC have won 61.2% of all the blocks mined since the 2024 halving, no-name blocks included, so 3 pools take more than half. The biggest four have won 72.1% of those blocks, against 58.8% of all the blocks mined from 2020 to 2024, counted the same way. In all, 15 named pools have won at least one block since the 2024 halving, and smaller pools counted together as other pools have won 1.6% of those blocks.
Mining has been gathering into fewer hands. From 2012 to 2016 it took 7 named pools to win half of all that era’s blocks, and the biggest four won 40.1% of them. Since the 2024 halving it takes 3, and the biggest four have won 72.1% of the blocks. Bitcoin’s first years can look the most spread out of all, but 90.7% of the blocks mined from 2009 to 2012 carry no pool name, so that era says more about what can be measured than about who was mining.
Was it always this identifiable?
Mining used to be anonymous. Of all 969,290 blocks mined since 2009, 30.1% carry no pool name, mostly from the early years when people mined alone at home. Of all the blocks mined since the 2024 halving, 3.2% carry none. Mining went from a hobby nobody signed to an industry that signs almost every block.
Who has won the most blocks ever?
AntPool’s name is on more blocks than any other pool’s: 11.4% of all 969,290 mined since 2009, no-name blocks included. F2Pool’s is on 8.2% of them and Foundry USA’s on 7.7%.
What should you keep in mind reading this?
Shares compare, raw counts do not. This era has used 129,290 of its 210,000 blocks, 61% of the way to the next halving, so its counts are still growing and only its percentages compare with finished eras.
And a name on a block says who most likely mined it, nothing more. It does not tell us who owns the reward today, and we never attribute anyone’s coins from it.

Bitcoin Mining Pools
Where it stands today
Of all 129,290 Bitcoin blocks mined since the 2024 halving, counting the ones with no pool name, Foundry USA has won 29.5% as of .
What is a mining pool?
Winning a Bitcoin block takes an enormous amount of guessing power, and a single machine could wait years for a win. So miners team up. A pool combines thousands of machines, wins blocks regularly, and splits the reward by contributed work. When a pool wins a block, it usually writes its own name into that block, which is what lets anyone count who mined what.
How are the blocks counted, and what does no pool name mean?
Every block Bitcoin has ever mined is read, and the names pools wrote into them are counted. Blocks with no recognisable name are counted honestly as their own slice rather than guessed at, and every share on this page counts them in its whole. Smaller pools are counted together as other pools. Most of the no-name slice is early Bitcoin, when people mined alone at home and had no pool name to write. That is why the early years look anonymous and the recent years do not.
Why split the count by era?
Bitcoin cuts its block reward in half every 210,000 blocks, roughly every four years, and everyone calls those halvings. They split Bitcoin’s history into natural chapters, so that is how this page groups the count. Comparing chapters shows something a single total hides: the leader changes. A pool that dominated one era can be a footnote in the next. No block mined before the 2020 halving carries the name of Foundry USA, which leads this era.
What does a name on a block tell you?
The name says who most likely mined the block, because pools sign their wins voluntarily and have little reason to lie. It does not say who owns the reward now, and it does not tell us which wallets belong to that pool. We count blocks, not coins, and we do not attribute anyone’s money based on a signature in a block. Also worth knowing: the current era is still being mined, so its counts grow every day and are only comparable to finished eras as percentages, never as raw totals.
