Understanding Bitcoin Mining Pools
Bitcoin miningWhat Is Bitcoin Mining? Bitcoin mining is the process of using specialized computers called bitcoin miners to systematically guess a number that completes a math equation. Whoever finds the number... is one of the fastest growing industries in the Bitcoin space right now. As more people wake up to Bitcoin, more people want to get their hands on it. Besides buying bitcoin directly, many have opted to mine it using their own computing power.
The problem, however, is that mining has become so competitive that solo miners without as much capital to expend are being priced out of the game. The solution? Bitcoin mining pools.
What Is A Bitcoin Mining Pool?
As Bitcoin mining becomes increasingly difficult, small miners have a harder time staying profitable. A mining pool is a group of Bitcoin miners that pool their hashWhat Is A Hash? A hash, or cryptographic hash, is a mathematical function that takes digital data of any size as an input and produces a digital output of a... power together to increase their chances of finding the next block and winning the block rewardWhat Is The Block Reward? The block reward is how Bitcoin miners are compensated for mining and adding blocks of transactions to the blockchain. The block reward is made up.... When a pool finds a block, each user in the pool receives a portion of the bitcoin reward, based on how much hash power they contribute to the pool. The operator of the mining pool also receives a small portion of the bitcoin reward to cover their costs.
How Do Mining Pools Work?
Here’s a general overview of how mining pools work:
- Pooling Resources: Miners in a pool contribute their computational power to collectively increase the chances of successfully mining a block. This collaboration is crucial because the probability of a single miner, especially with limited hash power, mining a block on their own is considerably low.
- Mining the Block: The pool’s combined hash power enhances the pool’s likelihood of finding the next block. Once finding it, the pool earns the block reward.
- Reward Distribution: Miners in the pool receive a portion of the block reward based on their individual hash power contributions. Miners who provided a greater share of the total hash power receive a proportionally larger share of the block reward, ensuring that miners are compensated for their effort.
Operator’s Reward: The operator or administrator of the mining pool also receives a small percentage of the block reward. This share helps cover the operational costs of maintaining the pool, including server expenses, maintenance, and any other overhead.Bitcoin mining pools revolve around the concept of “shares.” When a miner puts in the hash power to solve the block but isn’t chosen by the network to receive the block reward, they receive a share, which serves as proof of the miner’s contribution to the pool’s hash power.When the pool successfully mines a block, the reward is split among the miners based on the number of shares they hold. This system ensures that even if a miner doesn’t directly mine a block, they still receive a portion of the rewards proportional to their contribution.
Popular Mining Pool Reward Schemes
Not all Bitcoin mining pools are created equal, and there are more than 15 different ways that contributors can expect to earn their payouts.
Here are some of the most popular payout methods:
- Pay-Per-Share (PPS): PPS guarantees an instant payout based on the expected block reward for each of the valid shares contributed to the pool, regardless of whether or not the pool finds a block or not. Thus, PPS offers a reliable and straightforward payout to its contributors. In essence, PPS removes the “luck” of finding the next block, and instead absorbs the risk of the variance to maintain constant payments.
- Full Pay-Per-Share (FPPS): While PPS compensates miners based on the expected block reward, it doesn’t account for transaction fees. Along with the block reward, FPPS also calculates the average transaction feeWhat Is A Transaction Fee? A Bitcoin Transaction Fee, commonly known as a miner fee, is the amount of bitcoin that a sender attaches to their transaction to incentivize Bitcoin... over a set timeframe and shares it among the miners. By incorporating transaction fees into payouts, FPPS boosts the overall earnings of miners.
- Pay Per Last N Shares (PPLNS): PPLNS pays out a percentage of miners’ contributed shares to the total shares (N). The amount of shares contributed to finding the next block may vary since payments only go out after finding a block, so miners receive the actual value of the block reward, rather than an expected amount like in PPS. With PPLNS, you earn more shares as you mine, so it encourages consistent mining and loyalty to a single pool. The more shares a miner accumulates over time, the larger chunk of the block reward they receive.
- Pay-Per-Share+ (PPS+): A hybrid of both PPS and PPLNS, PPS+ pays out the block reward according to the PPS process, whereas it distributes transaction fees according to the PPLNS process.
So, in summary:
PPS | FPPS | PPLNS | PPS+ | |
Block Reward | Expected Value | Expected Value | Actual Value | Expected Value |
Transaction Fees | None | Expected Value | Actual Value | Actual Value |
The three largest mining pools: Foundry USA, AntPool, and F2 Foundry, each have their own payout methods.
- Foundry operates with a FPPS reward scheme
- Antpool offers PPS, PPS+, and PPLNS
- F2Pool offers PPS, FPPS, and PPLNS
Each payout method has its own time and place, so be sure to choose a mining pool and payout method that aligns with your own personal goals.
Why Are Bitcoin Mining Pools Important?
Since energy is geographically distributed, and more expensive in some places than others, Bitcoin mining has naturally dispersed across the globe. This dynamic creates an incentive for miners to operate in different physical locations but cooperatively share hash rate and block rewards.
Mining pools are the glue that brings this distributed hash power altogether.
So for small miners who are very unlikely to find the next block on their own, they can join a mining pool and create a new source of revenue. Though payouts are only proportional to the miner’s contribution, these consistent, expected payouts can help small miners pay off the upfront costs over time and be left with a steady stream of bitcoin entering their wallet address.
This way, everyone can truly enjoy the benefits of Bitcoin mining, not just centralized mining monopolies.
Benefits Of Joining A Mining Pool
Bitcoin mining pools have several benefits for small miners. These include:
- Lower barrier to entry: The obvious and greatest benefit – mining pools allow individual miners with limited hash power and resources to participate in Bitcoin mining.
- Increased reward chances: As part of a mining pool, you’ll have a greater shot at finding and/or reaping the rewards of the next block. Pooling resources with other miners increases the collective computational power, improving the odds of successfully mining a block.
- Stable earnings: While payouts may not be large, joining a Bitcoin mining pool can offer you a steady income stream to save for later in life. This predictability can help in financial planning and reduce the volatility often associated with solo mining.
- Reduced costs: Joining a mining pool is much more economically feasible for smaller players as opposed to spending thousands upfront to manage their own operations. Sharing infrastructure and operational expenses among pool members can mean more cost savings and less financial risk.
Despite the benefits, however, mining pools aren’t perfect.
Drawbacks Of Joining A Mining Pool
Don’t get too comfortable thinking you can just join a mining pool and forget about it. They come with their own set of downsides, including:
- Trust: Mining pools can sometimes be plagued with frauds or cheaters skimming rewards off the top of their pool contributors. Ensure that whichever pool you join, is reliable and carries a solid reputation behind it.
- Centralization Concerns: Concentrating hash power into a few large mining has raised concerns about the centralization of the network. However, since mining pools are made up of distributed participants, they’re much more resilient to coercion, and competition incentivizes good participation among mining pools, else they lose their network.
- Maintenance: Bitcoin mining is designed to become less profitable over time, so any profits made from mining comes from constant innovation and access to cheaper energy. This, however, requires that you update your system to maintain profitability over time.
- Lack of control: Since you don’t own the mining operation, you don’t have a say in how it’s managed. If a pool you’re a part of makes changes that you disagree with, you may have to find a new pool to contribute to.
It’s critical that you understand the ins and outs of any mining pool you get involved with so you don’t make a mistake and fall victim to unexpected scams or pay exorbitant fees.

Mining is resource-intensive, so always be aware of your electricity costs and hardware maintenance to see how they stack up against your potential earnings.
FAQs About Bitcoin Mining Pools
Q: How is solo mining different from a mining pool?
A: Solo miners provide all the necessary infrastructure and computational power independently to mine blocks. When they successfully mine a block, they receive the entire block reward. Bitcoin mining pools, on the other hand, collaborate with other miners by pooling together computational resources. Rewards are then distributed among pool members based on their contributed hash power.
Q: Why do Bitcoin mining pools require a fee?
A: Bitcoin mining pools often have operational costs such as server maintenance, infrastructure, security measures, and any employee salaries. The fees charged to pool members thus help cover these expenses, or serve as a profit margin for the pool operators. Before joining a pool, miners should always read about the fee structure and ensure that it aligns with their mining objectives.
Q: How do Bitcoin mining pools ensure fair rewards distribution among miners?
A: Bitcoin mining pools are practical for individual miners with limited resources. By joining a pool, you get the consistent payouts from mining while avoiding the technical maintenance, making it a more predictable and viable option for those who don’t possess extensive mining infrastructure.
