# What Does Bitcoin Mining Code Mean?

Let's say you had one legit $20 and one really good photocopy of that same $20. If someone were to attempt to spend both the real bill and the fake one, someone who took the trouble of looking at both of the bills' consecutive numbers would see that they were the exact same number, and consequently one of them had to be false.

That isn't a perfect analogy--we will explain in more detail below. .

Once a miner has confirmed 1 MB (megabyte) worthiness of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size ought to be increased to accommodate more information.

Note that I stated that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid off.

1MB of transactions can technically be small as 1 transaction (though this is not in any way common) or several thousand. It depends on how much information the transactions take up.

In order to earn Bitcoin, you need to meet two conditions. One is a matter of work, one is a matter of luck.

2) You have to be the first miner to arrive at the perfect answer to a numeric problem. This practice is also known as an evidence of work.

The good news: No advanced math or computation is involved. You may have discovered that miners are solving challenging mathematical problems--that's not true in any way. What they are actually doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") which is less than or equivalent to the target hash.

The bad news: Because it is guesswork, you need a lot of computing power in order to get there . To mine successfully, you need to get a high"hash speed," that is measured in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second (TH/s).

If you want to estimate just how much Bitcoin you could mine along with your mining rig's hash pace, 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 to the tens of thousands. Some miners--especially Ethereum miners--purchase individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

ExampleI tell three friends that I'm thinking of a number between 1 and 100, and I write that number on a piece of paper and seal it in an envelope. My friends don't need to guess the specific number, they simply have to be the very first person to figure any number that's less than or equal to this number I am thinking of.

Let us say I am thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both technically came at viable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .

In Bitcoin terms, simultaneous answers occur frequently, but in the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Normally, it's the miner who has done the work, i.e.

The losing block then becomes an"orphan block." .

Now imagine I pose the"figure what number I'm thinking of" question, but I'm not asking only three friends, and I am not thinking of a number More about the author between 1 and 100. Rather, I am asking millions of prospective miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it's going to be quite hard to guess the right answer.

The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not only of numbers, but also letters of this 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 know, we utilize the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
