Cryptocurrency mining has evolved from a solo endeavor into a collaborative effort, with miners pooling their computational power to increase the chances of successfully mining blocks. One of the most critical aspects of joining a mining pool is understanding how earnings are distributed. Most mining pools use one of four primary reward systems: PPS, FPPS, PPLNS, and PPS+. Each model offers a different balance of risk, reward stability, and payout structure. In this guide, we’ll break down these models, explain key mining concepts, and help you determine which system might be best for your mining strategy.
Key Concepts in Cryptocurrency Mining
Before diving into payout models, it’s essential to understand several foundational terms that shape how mining rewards work.
Block Rewards
Block rewards are the cryptocurrency tokens awarded to miners who successfully validate and add a new block to the blockchain. For example, Bitcoin started with a block reward of 50 BTC per block. This reward halves approximately every four years—a process known as the "halving." After three halvings, the current block reward stands at 6.25 BTC.
Transaction Fees
In addition to block rewards, miners earn transaction fees paid by users to prioritize their transactions on the network. These fees can contribute significantly to total income—often accounting for over 10% of a miner’s revenue, especially during periods of high network congestion.
Hash Rate (Computing Power)
Hash rate measures how many calculations a mining device can perform per second. The higher the hash rate, the greater the chance of solving the cryptographic puzzle required to mine a block. Think of it like buying lottery tickets: more tickets mean better odds of winning.
Luck Factor
“Luck” in mining refers to the variance between expected and actual block discoveries. If a pool has 10% of the network's total hash rate, it statistically should find 1 out of every 10 blocks. When it finds more, luck is high; when fewer, luck is low. Over time, luck tends to average out.
Mining Pools
Due to the immense difficulty of solo mining, most miners join mining pools—groups that combine hash power to improve block-finding probability. Rewards are then shared among participants based on their contributed computing power, minus a small fee for pool operations.
Understanding Mining Pool Payout Models
Now that we’ve covered the basics, let’s explore the four most common payout methods used by mining pools today.
1. Pay-Per-Share (PPS)
Under the PPS model, miners receive a fixed payout for each valid share they submit, regardless of whether the pool finds a block. This payout is calculated based on the statistical probability of finding a block with that share.
Imagine you hold 10% of the pool’s hash rate. Even if no blocks are found during a period, you still get paid as if you earned 10% of the expected reward. The pool operator assumes all the risk of variance.
- Pros: Stable, predictable income; immune to luck fluctuations.
- Cons: Higher fees; less common in major cryptocurrency pools due to financial risk for operators.
- Best for: Miners prioritizing consistent returns over maximum potential gains.
2. Full Pay-Per-Share (FPPS)
The FPPS model builds on PPS by including an estimate of transaction fees in addition to block rewards. Typically, pools calculate average fees over the past 24 hours and distribute them proportionally.
This means miners receive both:
- The expected block reward (like PPS), and
- A projected share of transaction fees.
- Pros: Higher average payouts than PPS; includes fee estimates.
- Cons: Operators face greater financial exposure, leading to slightly higher service fees.
- Market presence: Dominates with 51.7% of total network hash rate across major pools.

3. Pay Per Last N Shares (PPLNS)
Unlike PPS and FPPS, PPLNS only pays out when a block is actually found. Rewards are distributed based on the last “N” valid shares submitted before the block was mined—typically weighted toward recent contributions.
If your shares fall outside this window, you earn nothing—even if you contributed earlier.
- Pros: Lower fees; rewards loyal, consistent miners.
- Cons: Income fluctuates heavily based on luck and pool performance.
- Ideal for: High-hash-rate miners comfortable with volatility.
Despite its lower operational risk for pool operators, PPLNS accounts for just 4.5% of global hash allocation, indicating limited appeal among average users.
4. Pay-Per-Share Plus (PPS+)
PPS+ blends elements of both PPS and PPLNS:
- Block rewards are paid via the PPS method (fixed, predictable).
- Transaction fees are distributed using PPLNS principles (based on actual blocks found).
This hybrid approach offers:
- Stability in base income,
- Bonus upside when transaction fees spike.
It strikes a balance between security and opportunity—making it popular among mid-to-large-scale miners.
Which Mining Reward Model Is Best?
When comparing all models under equal conditions—hash rate, fees, and network stability—FPPS generally offers the best combination of reliability and return. It provides predictable earnings while including estimated transaction fees, making it attractive for most miners.
Here’s a quick market snapshot:
- FPPS: 51.7% hash rate share — dominant due to balanced risk/reward
- PPS+: 43.7% — strong alternative with hybrid benefits
- PPLNS: 4.5% — niche appeal for risk-tolerant miners
- PPS: Nearly obsolete — rarely used due to low inclusivity of fees
Pool operators also consider risk: FPPS requires substantial capital reserves to cover shortfalls during dry spells, so they often charge higher fees. Conversely, PPLNS carries minimal risk for operators and thus features lower fees.

Frequently Asked Questions (FAQ)
Q: What is a "share" in mining?
A: A share is proof that a miner has completed a portion of work toward solving a block. It’s used by pools to fairly measure contribution and distribute rewards.
Q: Is FPPS always better than PPLNS?
A: Not necessarily. FPPS offers stability and is ideal for consistent earnings, but PPLNS can yield higher returns during lucky streaks or high-fee periods—suited for experienced miners who can tolerate income swings.
Q: Why do some pools prefer PPLNS?
A: Because PPLNS shifts all variance risk to miners, it’s financially safer for pool operators. They only pay out when blocks are found, reducing liability during low-luck phases.
Q: Can I switch between payout models?
A: Yes—most pools allow users to select their preferred model upon registration or through account settings. However, switching frequently may impact earnings consistency.
Q: Does luck affect PPS and FPPS?
A: No—these models smooth out variance by paying expected values regardless of actual block discovery. Luck only impacts models like PPLNS where payouts depend on real outcomes.
Q: Are there hidden risks in FPPS?
A: The main risk lies with the pool operator, not the miner. If a pool miscalculates fee averages or faces prolonged bad luck, it could face insolvency—though reputable pools mitigate this with reserves.
Final Thoughts
Choosing the right mining pool and payout model significantly affects your profitability and peace of mind. While FPPS leads in popularity and performance, your choice should align with your risk tolerance, hash power, and mining goals.
Understanding these systems empowers you to make informed decisions—and avoid being misled by misleading promises or opaque structures. Whether you're a beginner or a seasoned operator, mastering payout mechanics is key to sustainable mining success.
