Bitcoin mining pools explained: shares, payouts and fees
Explainer · Mining desk · Published 17 October 2026 · By TradeSignalsHQQuick answer. A mining pool combines the work of many miners so that someone finds a block often, then splits the reward by how much work each miner proved with "shares". Pools differ mainly in how they pay: steady per-share payouts where the pool carries the luck, or block-by-block payouts where you do.
A single mining machine competing alone against the whole Bitcoin network might go years without finding a block. Pools turn that lottery into a regular income stream. This guide explains how a pool measures your contribution, how the common payout methods work, what the fee costs in numbers and why a few large pools matter for the network. It is educational only and is not advice to buy mining equipment or bitcoin.
What is a Bitcoin mining pool?
Miners compete to add the next block by hashing block headers until one falls below the network's target. The winner collects the block reward, which Bitcoin's developer documentation describes as the block subsidy plus the transaction fees paid by the block's transactions (Bitcoin developer guide: block chain). Since the 2024 halving the subsidy is 3.125 BTC per block; our halving page shows the full schedule.
The network's total work is enormous: at the difficulty set on 16 October 2026 it implies a hashrate of roughly 1,000 EH/s (exahashes per second), as our hashrate tracker shows live. A 200 TH/s machine (terahashes per second) is about one five-millionth of that. On its own it would expect to find a block roughly once every 95 years. A pool gathers thousands of such machines, finds blocks every day and shares out the proceeds.
How does a pool know how much work you did?
It sets an easier target. Bitcoin's developer documentation explains that pool operators give miners a target far easier than the network's, and each result that meets the pool's target is submitted as a share, which proves the miner did a certain amount of work. Now and then a share also meets the real network target, and that share becomes a block (Bitcoin developer guide: mining).
Shares are the pool's accounting unit. More hashrate means more shares per hour, so a miner's slice of the pool's shares tracks its slice of the pool's work. The same guide notes that miners receive block templates either through getblocktemplate, which hands them full transaction data and lets them modify the block, or through Stratum, which sends only the minimum needed so miners cannot inspect or add transactions.
How do FPPS, PPS+ and PPLNS payouts differ?
The payout method decides who carries the luck. A pool can find more or fewer blocks than expected on any given day, and fees vary from block to block. Three common methods, as two pools describe their own:
| Method | How you are paid | Who carries the luck | Listed fee (example) |
|---|---|---|---|
| FPPS (full pay per share) | A fixed amount per share for both subsidy and fees, based on network averages | The pool | 2.5% (Braiins Pool) |
| PPS+ (pay per share plus) | Subsidy paid per share; fees shared out from blocks the pool actually finds | The pool for subsidy, you for fees | 4% + 2% (ViaBTC) |
| PPLNS (pay per last N shares) | Subsidy and fees paid only when the pool finds a block, split by recent shares | You | 2% (ViaBTC) |
Braiins Pool, for example, says it calculates FPPS rewards after each UTC day as if the average 144 blocks had been mined, so your reward does not depend on how many blocks the pool found that day; it then deducts a 2.5% fee (Braiins Academy: rewards and payouts). ViaBTC describes PPLNS as paying both subsidy and fees only when the pool finds a valid block, which leaves more of the luck with the miner, and notes that neither method guarantees income (ViaBTC: PPS+ and PPLNS explained). Fees change, so always check a pool's current terms.
What does a pool payout look like in numbers?
Assumptions for this worked example: one machine at 200 TH/s, the network difficulty of about 140.58 trillion set on 16 October 2026, a subsidy of 3.125 BTC and an average of 0.02 BTC in fees per block. These are illustrations, not a forecast.
| Step | Value |
|---|---|
| Expected blocks per day for 200 TH/s (hashrate × 86,400 ÷ (difficulty × 232)) | 0.0000286 |
| Gross expected reward per day (× 3.145 BTC) | about 9,000 sats |
| After a 2.5% pool fee | about 8,780 sats |
| In dollars at an assumed $80,000 per BTC | about $7.02 |
Under FPPS that figure arrives every day, give or take changes in fees and difficulty. Under PPLNS the long-run average can be similar, but the daily amount swings with the pool's luck, and a small pool can go days without a block. Our mining revenue estimator lets you set your own hashrate, power use and electricity price, and the difficulty explainer shows how one retarget changes these numbers.
Why does pool concentration matter?
Pools decide which transactions go into the block templates their miners work on, at least when miners use template-only protocols. That gives large pools influence over block contents. Over the month to 17 October 2026, mempool.space attributed about 25% of blocks to Foundry USA, 21% to AntPool, 17% to F2Pool and 10% to ViaBTC, so the four largest pools found nearly three in four blocks (mempool.space mining pools). Attribution relies on tags pools put in their blocks and is an estimate.
Concentration is not the same as control: individual miners can switch pools, and a pool that misbehaved would risk losing them. But it is a number worth watching, alongside the difficulty adjustment, because it describes how the network's work is organised.
What should you check before joining a pool?
- Payout method. FPPS gives steadier income; PPLNS can carry a lower fee but more variance.
- Fee and how fees are shared. Compare the total cost, including any separate fee on transaction-fee income.
- Payout thresholds and costs. Minimum payouts and withdrawal fees matter for small miners; some pools offer Lightning payouts for small amounts.
- Track record and transparency. Look for published block lists, clear terms and a stable history.
- Your own costs. Electricity usually decides whether mining makes sense at all, whatever the pool.
Is pool data a trading signal?
No. Shifts in pool share describe where hashrate is pointed, not what the bitcoin price will do. If a channel presents pool data as a reason to buy or sell, ask what the claim is based on and how its past calls performed. The CFTC reminds investors that there is no such thing as a guaranteed investment or trading strategy (CFTC: understand the risks of virtual currency trading).
