Hi everyone. First off I would like to apologize if this is the wrong place for this.

I am trying to make my own profitability calculator based on data from whattomine and am a little confused in regards to equihash coins. I’m hoping someone can tell me what I am doing wrong here. This is the equation I am using and I have confirmed that it works when I use it for ethash coins:

As a specific example, if I have a hashrate of 400/s that equates to 34560000 hashes per day. According to the data on http://whattomine.com/coins.json, the difficulty for Zcash is 3948366.55255825, the block reward size is 10 ZEC, and the average exchange rate over the last 24 hours (to BTC) is 0.0630193181258134. This makes the equation as follows:

Based on this equation it should be 5.51607254 BTC worth of ZEC per day. That is obviously very wrong and the calculator built in to whattomine seems to indicate that something around 0.00066 BTC per day would be more realistic for 400h/s. However, this same equation seems to be spot on for ethash coins. Does anyone know what is different about equihash that would require me to adjust my equation?

That’s nice. I’m not making it for other people though. I’m making it for myself. The reason why isn’t relevant as that does not change how the equation works. Let’s please keep this on-topic and refrain from posting meme images.

I also made my own, i wanted it to query my miners for their hash rate, and Electrical use. This way its more accurate in the moment.

I will try to explain my variables as some aren’t show where they are grabbed.

fBlockTime is the blocktime as a float from the network API poolHash is the hashrate of the pool i am in. fnetworkHash is the network hashrate from the network API hashRate is my own hashRate fzecPrice is of course the ZEC Price. wattsCost is the power cost in my region. I set that in the app. poolPercent is the fee by the pool.

so i calculate mBlockTime, which is how long it takes to get a block in hours.
The i convert that to blocks per hour (bpHour) mBPHour is my personal blocks per hour, instead of the pools. hPerBLock is hours per block. dperBlock is days per block (for myself).
the bottom part is just making the calculations to give better stats in different time periods.

Not sure if this helps, but its how i did mine
var mBlockTime = fBlockTime / (poolHash / fnetworkHash) / 3600;
var bpHour = 1 / mBlockTime;
var mBPHour = ((hashRate/poolHash)*bpHour)*10;
var hPerBlock = 1 / mBPHour;
var dPerBlock = 0f;
if (hPerBlock > 24f)
{
dPerBlock = hPerBlock / 24f;
}
var hourly = mBPHour * fzecPrice;
var tWattCost = (watts / 1000) * wattsCost;
var tpoolCost = hourly * poolFeePercent;
var fHourly = hourly - tWattCost - tpoolCost;
var fDaily = fHourly * 24;

Thank you. That does help. I would still like to figure out how to calculate this based on the difficulty rather than by using the block time and network hashrate. However, this is my new equation:

This gives me much more accurate calculation for equihash coins compared to what I was doing before and it works for both ethash and equihash coins.

Still though, I am confused as to what the difficulty value represents for equihash coins. In ethash, the difficulty represents the chances of solving the block and receiving the block reward with any given 1 hash. So if the difficulty were 10 (just as a simple albeit unrealistic example), that would mean I have a 1/10 chance of solving the block with any given hash I produce and would then receive the full block reward. I can’t understand why that doesn’t apply to Zcash and this method of calculation I am using now seems like a workaround which involves an unnecessarily large amount of variables. Using this method produces slightly different values than what whattomine reports when I use their calculator, but at least it’s in the same ballpark for equihash coins now. When I use difficulty to do calculations for ethash coins, the resulting value I calculate is exactly the same as whattomine.

What about the calculators that I listed? Do you find any of them accurate? If I enter Supernova’s info network hash and my resources (~2,888 sol/s) into miningspeed.com, it shows a 56.345748 ZEC/mo. profit.

I’m new, so please excuse my lack of knowledge in this area, but why is everyone so obsessed with the pool that they mine with if the pool does not effect their yield?
