HMP FairShare Payout System
Every miner earns their fair share. Small miners get a boost. Loyal miners get rewarded. The block finder gets extra. Transparent, automatic, and built for the community.
💡 How It Works
When the pool finds a Bitcoin Cash block, the 3.15 BCH block reward is split using our HMP FairShare formula:
Goes to the miner who found the block. Scales with their active hours — the longer you mine, the bigger your finder reward.
Split equally among all miners below the hashrate threshold. Levels the playing field for small rigs like Bitaxe and NerdMiner.
Split equally among miners active for 4+ days. Rewards commitment to the pool.
Distributed proportionally to all miners based on shares submitted in the last 7 days.
Covers infrastructure, development, support, and on-chain transaction fees.
The math: Of each full block reward — 1% goes to the dev fee, 20% goes to the block finder as a bonus, 5% is split equally among miners connected 1+ hour as a participation bonus, and the remaining 74% is split among all miners by share of total difficulty submitted in the past 7 days.
The finder also earns their normal share of the 74% PPLNS pool — the finder's bonus is extra, on top of their proportional share.
🤔 Why HMP FairShare?
Most pools are either solo (winner-takes-all) or plain PPLNS (proportional only). HMP FairShare goes further — rewarding loyalty, protecting small miners, and giving the block finder a meaningful bonus:
- Consistent earnings — Every miner earns proportionally for every block found, even tiny hashrate miners. No more "nothing until you win" solo volatility.
- Finder's bonus incentive — The miner whose share actually solves the block gets a meaningful 20% bonus. This rewards contribution and keeps mining exciting.
- Fair for all sizes — Whether you have 1 kH/s or 100 TH/s, you earn your proportional share. Bigger hashrate = more shares = larger payout, but every hash counts.
- Reduced variance — Unlike solo mining where only one person wins, our hybrid system means everyone earns every time a block is found.
⏳ Payout Timeline
1. Block Found
A miner in the pool submits a share that solves a Bitcoin Cash block. The full 3.15 BCH reward is received by the pool wallet.
2. Round Calculated (Instant)
Within seconds, the system calculates each miner's share of the reward based on their contribution over the past 7 days. Credits are added to miner balances.
3. Coinbase Maturity (100 blocks / ~16 hours)
Bitcoin Cash requires 100 confirmations before coinbase rewards can be spent. The pool waits for full maturity to ensure the block is confirmed.
4. Payout Sent
Once matured, miners with balances above the 10,000 sat minimum threshold receive their BCH in a batched on-chain transaction. Balances below the threshold continue to accumulate.
5. Force Payout (90 days)
Any remaining balance above dust (546 sats) is automatically paid out after 90 days, even if it hasn't reached the minimum threshold. No miner's earnings are ever lost.
\📈 Real Example: 100 Miners
Here's what happens when the pool finds a block with 100 active miners. Payouts are based on the total share difficulty each miner submits during the 7-day PPLNS window, not hashrate alone. Higher hashrate generally produces more shares, but the actual accepted share difficulty is what determines your cut. Block reward: 3.15 BCH.
| Miner Type | Count | Approx. Hashrate | % of Total Shares | Share Pool Earned | Per Miner |
|---|---|---|---|---|---|
| Block Finder FINDER | 1 | 500 MH/s | 0.33% | 0.008 BCH | 0.638 BCH |
| High-End GPU Rigs (RTX 4090) | 5 | 20 GH/s | 66.23% | 1.544 BCH | 0.309 BCH |
| Mid-Range GPU (RTX 3070/3080) | 15 | 2 GH/s | 19.87% | 0.463 BCH | 0.031 BCH |
| Entry GPU (GTX 1660/RX 580) | 30 | 500 MH/s | 9.93% | 0.231 BCH | 0.008 BCH |
| CPU Miners | 49 | 100 MH/s | 3.25% | 0.076 BCH | 0.0016 BCH |
| Total | 100 | 100% | 2.3310 BCH |
How shares determine your payout: The pool assigns each miner a difficulty level based on their hashrate. When your miner submits a valid share, the difficulty of that share is recorded. Over the 7-day window, the total difficulty of all your accepted shares is compared to the total difficulty from all miners in the pool. That ratio determines your percentage of the 88% share pool. Hashrate is shown above as a reference, but your actual payout is always calculated from accepted share difficulty.
Finder's Bonus Breakdown: The block finder (a GPU miner with 500 MH/s) earns their normal share pool payout of 0.008 BCH plus the finder's bonus of 0.6300 BCH = 0.638 BCH total. Any miner on any hardware can be the finder.
Small miners and the long game: CPU miners earn smaller amounts from the share pool per block, but those balances accumulate over every block the pool finds. Bitcoin Cash finds blocks roughly every 15 seconds, so earnings add up much faster than other coins. The real opportunity for smaller miners is the finder's bonus. Every share your device submits is a chance to solve a block and earn the 20% finder's bonus. It doesn't matter what hardware found it. A CPU miner's share that solves a block pays the same finder's bonus as a high-end GPU rig's share.
For perspective: an entry GPU earning ~0.008 BCH per block would accumulate steadily as the pool finds blocks throughout the day.
🔑 Key Details
⏳ How the 7-Day Share Window Works
Your shares do not accumulate value indefinitely. The pool uses a rolling 7-day PPLNS window, which means only shares submitted in the 7 days immediately before a block is found count toward that payout.
A 7-day window rewards loyalty. If you've been mining consistently for a week and lose power for a few hours due to a storm or ISP outage, you keep the vast majority of your share weight. A 12-hour outage only costs you about 7% of your window, not 50%. It also discourages pool hopping and short-term hashrate rental attacks, since a single day of rented hashpower gets diluted by a full week of loyal miners' contributions.
If the pool goes an extended period without finding a block, shares older than 7 days fall out of the window. When a block is finally found, only miners who were actively hashing within the last 7 days receive a cut of the reward.
In short: stay connected, keep hashing, and when a block lands you will receive your proportional share of the reward based on your contributions over the past week.
