What Does Bitcoin Mining Code Do?
Let's say you had one legit $20 and one quite good photocopy of the same $20. If someone were to attempt to spend both the real bill and the imitation one, someone who took the trouble of looking at both of the bills' consecutive numbers would observe that they had been the same number, and thus one of them had to be false.
That isn't a great analogy--we will explain in more detail below. .
Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and can be an issue of controversy, as some miners believe the block size should be increased to accommodate more data.
Note that I said that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will receive paid off.
1MB of transactions can theoretically be as little as 1 transaction (although this is not in any way common) or several thousand. It depends on how much data the transactions take up.
In order to earn Bitcoin, you need to meet two conditions. One is a matter of effort, one is a matter of luck.
2) You have to be the first miner to arrive at the right answer to some numeric problem. This practice is also known as a proof of work.
The good news: No advanced math or computation is involved. You might have heard that miners are solving difficult mathematical problems--that is not true in any way. What they're doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") which is less than or equivalent to the target hash.

The bad news: Since it's guesswork, you need a lot of computing power in order to get there . To mine successfully, you need to get a higher"hash rate," which is quantified in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).
If you want to estimate how much Bitcoin you can mine with your mining rig's hash rate, the website Cryptocompare provides a helpful calculator.
Either way a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from $500 into the tens of thousands. Some miners--particularly Ethereum miners--buy individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photo below is a makeshift, home-made mining i thought about this machine. The cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal rod.
Example: I tell three friends that I'm thinking about a number between 1 and 100, and that I write that number on a sheet of paper and seal it in recommended you read an envelope. My friends don't have to guess the exact number, they just must be the first person to guess any number that is less than or equal to the number I'm thinking of.

Let us say I am thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they've both technically came at viable answers, since 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer to the target answer of 19. .
In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented which can be equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --which miner to honour. Normally, it's the miner that has done the work, i.e.

The number preceding has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that
In order to understand what these letters are doing in the middle of numbers, let us unpack the word"hexadecimal."
As you knowwe utilize the"decimal" system, which means it's base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
