HMP FairShare Payout System
Every miner earns their fair share. Small miners get a boost. Loyal miners get rewarded. The block finder earns extra, scaled by active mining hours. Transparent, automatic, and built for the community.
💡 How It Works
When the pool finds an eCash block, the 3,125,000 XEC block reward is split using our HMP FairShare formula:
Covers pool operations, infrastructure, and support.
Goes to the miner who found the block. Scales with active hours, up to 25% at the 168h tier.
Split equally among miners active 4+ days (96h) with steady uptime in the payout window.
Split equally among miners below 10 TH/s. Bitaxe, NerdMiner, and hobby rigs all qualify.
Distributed proportionally to all miners based on shares submitted in the last 7 days.
Weighted finder tiers: The finder bonus scales with how long you've been actively mining. Unused finder percentage flows back into the PPLNS pool.
| Active Mining Hours | Finder Bonus |
|---|---|
| Under 8 hours | 5% |
| 8 – 24 hours | 7% |
| 24 – 48 hours | 10% |
| 48 – 96 hours | 15% |
| 96 – 168 hours | 20% |
| 168+ hours | 25% (max) |
HMP FairShare: Every block reward is split with a 0% pool fee, up to 25% weighted finder bonus, 6% loyalty (equal split among eligible miners), 3% small miner boost (equal split below 10 TH/s), and 66% PPLNS (proportional by 7-day shares).
The finder also earns their normal PPLNS share, the finder 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 still giving the block finder a meaningful bonus:
- Small Miner Boost (3%) , Equal cut for every rig under 10 TH/s, every block. A Bitaxe or NerdMiner earns the same boost as the next small miner.
- Loyalty Bonus (5%) , Miners active 4+ days (96 hours) earn an equal share. Consistency is rewarded, not just raw power.
- Weighted Finder's Reward (up to 25%) , The block finder earns extra, scaling from tiered steps up to 25% at 168h active mining hours.
- PPLNS Base (66%) , The bulk of the reward is still proportional, more shares, larger cut. Fair and predictable.
- Reduced variance , Every miner earns every time a block is found. No "nothing until you win" volatility.
⏳ Payout Timeline
1. Block Found
A miner in the pool submits a share that solves an eCash block. The full 3,125,000 XEC 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 at your registered ecash: payout address.
3. Coinbase Maturity (100 blocks / ~17 hours)
eCash 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 1,000 XEC minimum threshold receive their XEC in a batched on-chain transaction. Balances below the threshold continue to accumulate.
5. Force Payout (90 days)
Any remaining balance above the dust limit 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. Block reward: 3,125,000 XEC. Example assumes the finder is at the 168h+ tier (25% max).
| Miner Type | Count | Approx. Hashrate | % of Total Shares | PPLNS Earned | Loyalty + Small | Per Miner |
|---|---|---|---|---|---|---|
| Block Finder FINDER | 1 | 1.2 TH/s | 0.33% | XEC | 4,063 XEC | 635,869 XEC |
| Large ASIC (S19/S21 class) | 10 | 100 TH/s | 55.00% | XEC | 113,438 XEC | |
| Mid ASIC / Home Miner | 25 | 25 TH/s | 30.00% | XEC | 24,750 XEC | |
| Bitaxe / Small ASIC | 40 | 2 TH/s | 10.00% | XEC | 4,063 XEC each | 9,219 XEC |
| ESP32 / NerdMiner | 24 | 500 GH/s | 4.67% | XEC | 4,063 XEC each | 8,078 XEC |
| Total | 100 | 100% | 2,062,500 XEC | 406,250 XEC |
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 from all miners. That ratio determines your percentage of the 66% PPLNS pool.
Finder's Bonus Breakdown: The block finder (Bitaxe at 1.2 TH/s, 168h+ tier) earns their normal PPLNS payout of XEC, loyalty + small bonuses of 4,063 XEC, plus the finder's bonus of 781,250 XEC = 635,869 XEC total. Any miner on any hardware can be the finder.
Small miners and the long game: Bitaxe and NerdMiner rigs earn smaller amounts from the PPLNS pool per block, but those balances accumulate over every block the pool finds. The real opportunity for smaller miners is the weighted finder's bonus, every share your device submits is a chance to solve a block. A Bitaxe share that solves a block pays the same finder bonus as an ASIC's share.
🔑 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, you keep the vast majority of your share weight. It also discourages pool hopping, 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.
