💡 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.

� Hybrid Payout System

HashedMax Unity Pool uses a hybrid PPLNS + finder's bonus system. When the pool finds a block:

• 1% Dev Fee — covers infrastructure, development, and transaction fees
• 20% Finder's Bonus — goes to the miner who found the block
• 5% Participation Bonus — split equally among miners connected for 1+ hour
• 74% PPLNS Share Pool — distributed to all miners proportionally based on shares in the last 7 days

The block finder also receives their normal proportional share — the bonus is extra. This means every hash you submit is both a contribution to your steady earnings and a lottery ticket for the finder's bonus.
