Bitcoin Mining Pool Distribution

Which pools found Bitcoin's recent blocks — each pool's share of all blocks mined in the selected window, attributed from coinbase tags.

The big number is the share of blocks won by the current #1 pool in the selected window.
Pool Share of Blocks
One bar, 100% of blocks in the window — each segment is one pool's share. Colors match the list below.
Bar length = the pool's absolute share of all blocks in the window. Attribution comes from coinbase-transaction tags; untagged blocks appear as "Unknown".

What is a mining pool?

A mining pool combines the hashrate of many independent miners and splits the block rewards among them in proportion to the work each contributed. Pools exist for one reason: variance smoothing. Finding a block is a lottery — a small miner alone would wait years between wins, while a pool wins often and pays everyone a steady trickle. The pool changes when you get paid, not how much you earn on average (minus the pool fee).

expected_time_to_a_solo_block = (network_hashrate / your_hashrate) × 600 s
expected_blocks_per_day      = (your_hashrate / network_hashrate) × 144
example: 100 TH/s against a 1,000 EH/s network → 10,000,000× → ≈190 years to a solo block on average

The example is illustrative — see the live network hashrate for the current figure. Averages hide the pain: solo block-finding is exponentially distributed, so you could easily wait several times the average.

Payout schemes, one line each

FPPS (Full Pay Per Share): the pool pays you the expected value of both subsidy and transaction fees for every share you submit, regardless of whether the pool found blocks — the pool carries the luck risk. PPLNS (Pay Per Last N Shares): payouts come from blocks the pool actually found, split over the last N shares — your income tracks the pool's real luck, lower fee, more variance. PPS+: a hybrid — the block subsidy is paid at expected value (PPS) while transaction fees are shared from actual found blocks.

FPPS or PPLNS — which do you want?

Same machines, same shares, same long-run expected earnings — the schemes differ only in who holds the luck. FPPS pays you the expected value of subsidy plus transaction fees for every share, every day, whether or not the pool found blocks: the pool absorbs the variance and prices that insurance into a higher fee. PPLNS pays only from blocks the pool actually finds, split over the last N shares: no variance premium, but your income rides the pool's real luck — and because your shares age out of the window when you leave (and ramp up from zero when you join), it quietly penalizes pool-hopping.

The honest decision rule from the miner's seat: if the income has a job — a power bill due monthly — take an FPPS-type scheme and treat the extra fee as the cost of predictability. If you want the lowest long-run fee, plan to stay on one pool, and can shrug off dry stretches, PPLNS keeps the premium in your pocket.

How dry is dry? At Bitcoin's 144-blocks-a-day pace, a pool with 1% of network hashrate expects about 1.4 blocks a day; at 0.1% it is about one block a week — and at an average of one a week, Poisson arithmetic says roughly one week in three passes with no block at all. On FPPS those weeks pay the same as any other; on PPLNS they pay nothing. That, concretely, is the swing you are choosing to hold. Definitions live in the glossary: FPPS · PPLNS.

How to read concentration

The two numbers that matter are the #1 pool share and the top-3 combined share. When the top three pools together exceed 50% of blocks, three coordinating parties could in principle out-build the rest of the network — a coordination risk worth watching, not an accusation against any specific pool. Two caveats keep this honest: pools do not own the hardware — individual miners can and historically do repoint their machines within hours when a pool grows uncomfortably large — and block share over a short window is noisy, so a pool's 7-day share can differ by several points from its true hashrate share purely by luck.

Why pool attribution is imperfect

Nobody signs blocks with a verified identity. Pools are identified by tags in the coinbase transaction and by known payout addresses. A pool can change its tag, a private miner can copy one, and blocks with no recognizable tag are lumped into "Unknown". Treat small slices and the Unknown share as approximate — the big pools' shares are reliable, the tail is fuzzy.

FAQ

Which Bitcoin mining pool pays best?
Over the long run, pools on the same payout scheme pay out almost the same amount. The real differences are the pool fee, the payout scheme (FPPS pays steady expected value, PPLNS tracks the pool's actual luck), and short-term variance. No pool has structurally higher rewards — compare fees and minimum-payout thresholds instead.
What happens if my pool finds no blocks?
On a PPLNS pool your payout comes from actual blocks found, so a dry round pays less — or nothing — for that stretch. On an FPPS or PPS pool you are paid the expected value of your submitted shares anyway: the pool absorbs the luck variance and typically charges a slightly higher fee for doing so.
Should I pick FPPS or PPLNS?
Pick by the job the income does. If it pays bills, an FPPS-type scheme buys a steady, predictable payout — the higher fee is the price of the pool absorbing luck. If you want the lowest long-run fee and can sit through zero-block weeks without switching pools, PPLNS avoids that premium — but it penalizes pool-hopping, because your shares age out of the payout window when you leave. Long-run expected earnings are the same either way; you are only choosing who holds the variance.
Can a mining pool steal my hashrate?
A pool controls the block templates your machines work on, so it decides what you mine — but it cannot spend your coins, and you can audit the shares you submitted against the payouts you received. Your practical protections are the pool's share logs, its payout history, and the ability to point your miners at a different pool at any time.
