How GUIMiner Helps Show New Users How Shares And Difficulty Work

This guide explains the mechanics behind submitting valid computational proofs to a mining pool. The interface translates your hardware’s processing power into accepted results, directly impacting your portion of the collective reward. Each submitted proof, known as a ‘share,’ has a specific computational target set by the pool.
The pool’s computational target determines the frequency of your accepted submissions. A lower target means your machine must perform more calculations to find a valid result, reducing your submission rate. For example, a pool might set a target requiring one valid submission per several million attempts. This parameter, often called ‘pool difficulty,’ is adjustable. Increasing it can reduce network latency overhead, while decreasing it provides more frequent, smaller reward confirmations.
Your earnings are calculated from the count of these accepted proofs over a specific period. The pool’s system tracks every valid submission you make. A higher individual submission rate, relative to the total pool effort, translates to a larger slice of the block reward when it is found. Monitoring your submission rate in the software’s statistics panel provides a real-time gauge of your contribution’s effectiveness.
Understanding the relationship between share difficulty and pool payout in Guiminer
Configure the share difficulty setting within your pool’s worker configuration page, not directly in the Bitcoin mining tool GUIMiner interface. A higher value for this parameter demands more computational power to validate a single unit of work submitted to the pool.
Selecting a significantly elevated pool target reduces network traffic and latency, which can increase the proportion of accepted work units. For solo operators, this setting directly influences the complexity threshold for discovering a valid block. In pooled environments, it governs the frequency of your contribution reports.
Your earnings are calculated based on the quantity of these validated work units you submit. A configuration with a higher complexity yields fewer, but more valuable, submissions. Conversely, a lower setting generates a higher volume of less valuable contributions. The total payout remains consistent over time, but the variance in your income stream is affected.
Adjust this parameter to match your hardware’s hashrate. High-performance systems benefit from a raised threshold to minimize stale submissions. Less powerful setups should use a lower value to ensure a steady flow of accepted work, providing consistent feedback and smaller, more frequent payouts.
Why your share count fluctuates and interpreting it
Your reported submission tally varies because mining involves a probabilistic process of discovering block solutions. The pool’s current complexity level directly influences this oscillation. A higher pool target means your rig submits partial results more frequently, increasing the counter. A lower target reduces the submission rate, making the number appear stagnant.
Reading the statistics panel
Focus on the average hashrate over a 24-hour period, not the instantaneous share count. This metric provides a stable view of your hardware’s performance. Monitor the accepted versus rejected submissions. A high rejection percentage indicates connection or configuration problems that require immediate attention.
Short-term spikes or dips are normal. Consistently low accepted figures over several hours, however, signal an issue. Check your internet stability, hardware temperature, and mining client configuration. The pool’s difficulty adjustment is automatic; your primary indicator of health is a consistent, long-term average hashrate aligned with your equipment’s expected output.
FAQ:
I’m completely new to this. What is a “share” in Guiminer and why does the program keep talking about them?
A share is a small, intermediate unit of work that your mining hardware completes and submits to the mining pool. Think of it like a progress report. You’re not trying to find the single, winning Bitcoin block all by yourself (which is extremely hard). Instead, the pool gives you a much easier problem to solve. Each time your computer finds a solution to this easier problem, it sends a “share” to the pool as proof that you are working. The pool then rewards you based on the number of valid shares you submit. This system allows individual miners with less powerful equipment to receive a steady, smaller income rather than relying on a massive, unlikely solo win.
My Guiminer shows a high “Difficulty” number. What does this setting actually control?
The difficulty setting in Guiminer directly affects how hard it is for your hardware to find a share. A higher difficulty means your computer has to perform more calculations to find a valid share. While this results in fewer shares being submitted overall, each share is “worth” more to the pool. For very powerful mining rigs, a higher difficulty can be better because it reduces the amount of communication with the pool server. However, for a standard PC with a single graphics card, using the pool’s default or a lower difficulty is usually recommended. This allows you to submit shares more frequently and have a smoother, more consistent earnings stream.
Why does my accepted share count sometimes go down or reset?
This is normal behavior and relates to how the pool tracks your work. Most pools use a “round-based” system. When you submit shares, you are contributing to the pool’s effort to find the next Bitcoin block. Your share count represents your contribution to the *current* round. Once the pool successfully finds a block, the round ends, the block reward is distributed, and the share counter resets to zero for the next round. So, seeing your shares reset isn’t an error or a loss of work; it simply means the pool solved a block and is now starting fresh.
Is there a connection between the network difficulty and the difficulty I set in Guiminer?
Yes, but they are two separate concepts. The network difficulty is a global value set by the Bitcoin protocol itself. It determines how hard it is for anyone in the world to find a new Bitcoin block, and it adjusts automatically every 2016 blocks to keep the block discovery time around 10 minutes. The difficulty you see in Guiminer is a local setting for your connection to the mining pool. It’s a way for the pool to manage the flow of work it sends to you. The pool might adjust your worker difficulty based on your hash rate, but it is always a much lower number than the immense global network difficulty.
My hash rate is high, but I’m getting very few accepted shares. What could be wrong?
Several issues can cause this. The most common culprit is using a difficulty setting that is too high for your hardware. Your computer is working hard (high hash rate) but failing to complete the difficult work units in a reasonable time. Try lowering the difficulty setting in Guiminer. Another possibility is hardware instability. If your graphics card is overclocked too much or is overheating, it might produce incorrect calculations, leading to rejected “invalid” shares. Check your temperatures and consider a more stable configuration. Finally, a poor internet connection can cause delays, making your submitted shares arrive too late to be counted by the pool.

Shares: puzzle pieces. Difficulty: how hard they are to find. Guiminer shows the hunt.
ShadowBlade
Oh great, another tutorial for the clueless. You needed software to explain that more hashes equal more money? Maybe just read the source code instead of wasting cycles. The only difficulty here is your hashrate.

Oh, so we’re explaining shares now? How quaint. Finally, the new crop of dreamers can see the cold, hard math behind why their space heater earns three pennies a month. Let them gaze upon the “difficulty” and weep for their electricity bill.

My screen glows with these cryptic numbers, this ‘difficulty.’ Is each solved share a tiny, digital sob? A tear shed by my GPU, weeping for a future where it is no longer enough? When the numbers climb, are we just building our own, beautiful, heartbreaking prison?
StarlightVixen
Okay, so the part about shares being these little proof-of-work chunks makes a weird kind of sense… but my brain just short-circuits trying to connect that to the actual network difficulty. If the difficulty is this massive, universe-sized number, how does my dinky little GPU even find a single one of these “shares”? Is it just pure, dumb luck, like winning the world’s most confusing lottery? Can someone who isn’t a math wizard explain what it *feels* like for your rig when it actually finds a valid share versus when the difficulty spikes? I keep staring at the numbers and feel like I’m missing the basic picture everyone else just gets.
Daniel Harris
My head hurts. If difficulty adjusts to keep block time steady, why do we even see our personal share difficulty? What’s the real difference between a high and low diff share for the pool? Am I just missing the point?

Wow, this is so cool! I finally get it! Shares are like little “proofs” of work, and difficulty is how hard my computer has to think to find one. Guiminer makes this so visual and easy to understand. Now I feel super confident to start my own mining adventure. This is amazing
