⛏️ Mining Connection Guide

📋 What You Need

• A Bitcoin Wallet Address — This is where your mining rewards will be sent. You can use any wallet (Coinbase, Cash App, Exodus, BlueWallet, etc.). Your address starts with 1, 3, or bc1.
• Mining Hardware — Any SHA-256 mining device: Bitaxe, NerdMiner, ASIC miner, or even an ESP32 hobby miner.
• Internet Connection — Your miner needs to stay connected to submit shares to the pool.

🔧 How to Connect (Step-by-Step)

Follow these simple steps to start mining:

Step 1: Choose Your Port

Scroll down to find the port that matches your miner hashrate. Using the wrong port can cause connection issues.

Step 2: Configure Your Miner

In your miner settings, enter these three pieces of information:

Replace PORT with your chosen port number (e.g., 3334 for Bitaxe). Replace YOUR_BITCOIN_ADDRESS with your actual Bitcoin address. The .workername is optional — use it to identify multiple miners.

Step 3: Start Mining

Save the settings and start your miner. Within a few minutes, you should see shares being accepted. Check your stats at hmpool.io by entering your Bitcoin address.

Step 4: Wait for Payouts

You earn a share of every block the pool finds. Once your balance reaches 10,000 sats (0.0001 BTC), you will receive an automatic payout. Even tiny miners contribute and earn!

❓ Common Questions

• Why am I getting rejected shares? — Usually means you are on the wrong port for your hashrate. Try a different port with higher difficulty.
• Why do I not see my miner on the pool? — It can take 1-2 minutes after connecting. Make sure your address is entered correctly (case-sensitive for bc1 addresses).
• How long until I get paid? — Depends on the pool finding blocks and your share of the work. Small miners may need to wait for multiple blocks to reach the minimum payout threshold.
• What is a worker name? — An optional label after your address (e.g., bc1q...xyz.bitaxe1) that helps you identify which miner is which if you have multiple devices.

💡 What is Suggested Difficulty?

When your miner connects to the pool, it can request a specific starting difficulty using the stratum protocol's mining.suggest_difficulty message. This tells the pool how hard each share should be, based on your miner's hashrate.

Why does it matter?

• Too low: Your miner submits too many easy shares, wasting bandwidth and pool resources. Some pools will disconnect miners that spam low-difficulty shares.
• Too high: Your miner takes too long between shares, making your hashrate appear choppy on stats pages. You won't lose any rewards — just slower feedback.
• Just right: Aim for roughly 1 share every 10-15 seconds. The pool's VarDiff will fine-tune it automatically after you connect.

How to set it

Most mining firmware has a "Custom Difficulty" or "Suggested Difficulty" field in its pool configuration. Some firmware uses the password field — for example: d=2048 as the password. If your miner doesn't have a difficulty setting, don't worry — the pool will assign one based on the port you connect to.

Quick formula

suggested_diff ≈ hashrate_in_GH/s × 4.3

Example: A 500 GH/s Bitaxe → 500 × 4.3 ≈ 2,150 → use 2,048. A 14 TH/s S9 → 14,000 × 4.3 ≈ 60,200 → use 65,536.

💰 HMP FairShare Payout System

HashedMax uses the HMP FairShare payout system — designed to reward everyone fairly, from hobby miners to industrial operations. When the pool finds a block:

• 1% Pool Fee — Covers infrastructure, development, and transaction fees
• 20% Finder Reward — Goes to the miner who found the block (any miner can be the finder!)
• 5% Participation Bonus — Split equally among all miners connected for 1+ hour
• 74% PPLNS Share Pool — Distributed proportionally based on shares submitted over the last 7 days

Why HMP FairShare?

• Fair for all sizes — Whether you have 1 kH/s or 100 TH/s, you earn proportional to your contribution
• Finder Reward — Every hash is a lottery ticket. The miner who finds a block gets a 20% bonus ON TOP of their normal share
• Participation Bonus — Stay connected and earn a piece of the 5% participation pool
• 7-Day Window — Your shares count for 7 days, so occasional downtime does not wipe out your earnings
