Dogecoin achieved its goal to get me interested in all this cryprocurrency stuff. Here is an ELI5 of what I have understood so far. Please complain if I understood something wrong. The following wall of text does not explain stuff like blockchain, 'the fork', how coins are created or transferred, peer-to-peer structure, or protocol.

It tries to explain: • What does my CPU/GPU do all the time? • What is a hash function? • What is hash-rate and why does the pool server display a different number than my software?

• Do I get a coin every time cgminer says 'yay'? • What is the deal with 'Scrypt' and the difference between Bitcoin and Dogecoin/Litecoin? Let's start with the number 12. Then divide it by 4. The result of this calculation is 3. That was not too hard. We can do this backwards as well: if we know that the result is 3 and we divided something by 4, we can calculate 3*4=12 and know the number we started with.

Now we can think about dividing the number 84 by 4. Since we already calculated the result of 12/4 and 84 is larger than 12, we know that the result will be larger than 3.

Decred DCR Mining On Pc. We already know something about the result of this calculation without actually having to calculate it. Now something different.

We start with the number 12 again, but this time we calculate the remainder after dividing by 7. So, in integer calculation 12/7=1, remaining 5. Now let's try this backwards again. We know that the result is 5 and it's the remainder after dividing by 7. So we started with the number 5, or 12, or 19, or 26.? Somehow, it does not work this time.

Lots of start values are possible. If we now think about starting with the number 84 instead of 12, can we say something about the result without calculating it? Not really, all results are between 0 and 6, but that's it. So, this calculation does not work backwards and you can't predict something about the result without actually calculating it. So you will hopefully believe me now that it's possible to have a much more complicated version of such a formula with the following properties: • If you put in a number, you have no idea what the result will be.

If you just change a single bit of the input number, the result will be completely different, unpredictable, basically random. Zcash ZEC Mining Power Calculator. • You cannot go backwards.

If you have the result of the calculation, any number could be the number you started with. Such a formula is called. That's what your computer is busy calculating all the time when it's mining.

Let's first consider 'solo mining' (= without a pool, most miners don't do that). Your computer gets a personal.

If anybody (world-wide) manages to solve the problem, everybody gets a new one, so you only have a short time available to work on it. The huge number has a few digits (') which can be changed to whatever you like. You solve the problem and win the lottery and get lots of DOGE when you find the 'right' digits. The digits are 'right' when the result of a cryprographic hash function of the huge number is smaller than a given. Since you can't predict the results, the computer has to try as many combinations as possible, every time calculating the hash function and checking if the result is low enough to win. The threshold determines the and it changes from time to time. Unfortunately the threshold is so low that the chances of winning are very low.

You are also competing with thousands of other computers trying the same (all have their own personal numbers, though, so nobody works on the same huge number). All you can do is maximize your chances by calculating as many hash results as possible per second. Hashes per second is the hash-rate. A higher rate gives you higher chances of winning.

In the end, you might win only a few times a year or so. A GPU works better for this than a CPU because a GPU consists of more calculating cores than a CPU. Every is simpler than a CPU core, but it's good enough to calculate the hash function. And with many cores you can calculate many hash results simultaneously. If you want to win the lottery you might consider playing together with others: several people buy lottery tickets and if anybody wins, the prize will be split among all.

It increases your chances of winning but decreases the amount you win every time. The mining pools work the same. All computers combine their calculation power. How do you make sure the nobody cheats and that the prize is split in a fair way? What if someone only pretends to buy lottery tickets?

Your mining program shows your current hash-rate. The higher your hash-rate is the higher your part of the prize should be. If the mining program would just transmit its hash-rate to the pool, everybody who knows how to use a compiler could manipulate the mining software and transmit any imaginary super-giga-hyper hash-rate, trying to cheat. So the idea is that your mining software has to prove that it's working hard trying to solve the right problem.

To accomplish this, the pool has its own threshold for the hash results, which is higher than the 'official' threshold to win the lottery. It is set in a way that your software has a chance to achieve this a few times per minute. I'll use a few numbers for illustration (the real numbers are much different).

Let's say the chances of winning the official coin lottery are 1 in a million. The pool might set its threshold to give you a chance of 1 in 1000. This means that, on average, you need 1000 tries to get a hash value below the thresold. If your crappy PC can calculate 100 hashes per minute it needs 10 seconds for 1000 hashes. So, on average, every 10 seconds it has a result to transmit to the pool. The pool server checks if this is correct (if hash value is below threshold and you have been working on the right huge number).

If the pool is happy with your number, you have successfully submitted a 'share'. The number you submitted is probably not worth anything because it does not win the coins because it is not below the 'official threshold', but it is a proof that your computer is doing its work. That's when cgminer says 'PROOF OF WORK RESULT: true (yay!!!)'. Now the pool server can measure how often you submit shares. If, on average, you submit shares every 10 seconds and the chances for generating a share is 1 to 1000, it can calculate that your computer is working at a hash-rate of 100 hashes per second.

So there is no need to transmit the actual hash-rate to the pool server. This also explains why the hash-rate on your PC and on the pool sometimes show different values. If you are on a lucky streak and temporarily generate more shares than average, the pool might show a higher value than your mining software. The other way round is also possible. And if you overclocked your GPU too much or use the wrong settings for your graphics card, the pool might show a very low hash-rate because your PC is only calculating garbage. So it does not make sense to optimize your miner to display a super high hash-rate and your calculation results are crap. Make sure that it always calculates correct results (no hardware errors and few rejected shares).

The pool server has to be happy with your results, otherwise you get paid less than it could be. Scrypt: Bitcoin vs.

Litecoin/Dogecoin I always hated these chain-math exercises at school: Take the number 5, multiply by 2, add 4, subtract 6. If you don't suck as much at mental arithmetic as I do, you can do this entirely in your head. This is an illustration of the cryptographic hash function used by Bitcoin. You only need to perform a long chain of calculations.

It's easy to put thousands of small optimized calculation units on a chip and calculate this function extremely fast and in parallel. These special chips are so powerful at calculating this special function that your expensive gaming PC looks like a pocket calculator in comparison. The Litecoin inventors wanted to have a coin where everybody with a PC should be able to take part in mining and get a decent chance to win some coins, without having to buy special equipment. They chose a which works more like this: • Take the number 5 (start number) • multiply by 2 (first result) • subtract 1 (second result) • add 4 (third. You get it) • multiply by second result • subtract first result • divide by 4th result • and so on.

While doing this you don't know if or when each intermediate result will be needed again in the future. This time forget about doing this in your head. Grab a piece of paper a thick notebook with hundreds of pages to write down all the intermediate results. In the end you spend more time shuffling through the pages, retrieving and writing down results, than performing the actual calculations. On a computer this means: the Scrypt algorithm needs a good amount of RAM ( for Litecoin/Dogecoin) and the RAM speed is as important as the calculation speed. If you now want to create a chip with thousands of calculation units, you have to give every calculation unit enough RAM. The RAM takes more space on the chip than the calculation unit.

What can you do? • Make a large chip. As a result, the chip will be extremely expensive.

• Put less calculation units on the chip. Then you lose also much of your calculation power.

• Attach external RAM to the chip, like on a graphics card. Since the RAM speed determines the speed of the calculation, that thing will not be much faster than a graphics card because it uses the same kind of RAM.

At least, that's the theory. The future will show if this turns out to be true. Dogecoin uses the same algorithm as Litecoin, this is why you can use the same mining software. Some other parameters are different: how many coins there will be, how the difficulty threshold is set and such things.
