# All About Bitcoin Mining Code

Let us say you had one legit $20 and one really good photocopy of the same $20. If someone were to try to spend both the true bill and the fake one, someone who took the trouble of looking at either of the invoices' consecutive numbers would see that they were exactly the same number, and consequently one of them had to be false.

This isn't a great analogy--we will explain in more detail below. .

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

Note that I said that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who verifies transactions will receive paid out.

1MB of transactions can theoretically be as little as 1 transaction (though this is not in any way common) or several thousand. It depends on how much data the transactions consume.

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 reach the perfect answer to a numeric issue. This practice is also known as a proof of work.

The good news: No advanced math or computation is involved. You might have discovered that miners are solving challenging mathematical problems--that is not true at all. What they're 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 hash.

The bad news: Because it's guesswork, you need a good deal of computing power in order to get there . To mine , you need to have a higher"hash rate," which 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 site Cryptocompare offers a very helpful calculator.

Either way a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These find out here now can run from $500 into the tens of thousands. Some miners--especially Ethereum miners--purchase individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The graphics cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

Case in point : I tell three friends I'm thinking of a number between 1 and 100, and that I write that number on a piece of paper and seal it in an envelope. My friends don't need 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's say I'm thinking about 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 workable answers, since 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 which can be equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Typically, it is the miner that has done the most work, i.e.

The losing block then becomes an"orphan block" .

Now imagine I present the"figure what number I'm thinking of" question, however I'm not asking only three friends, and I'm not thinking of a number between 1 and 100. Instead, I'm asking millions of prospective miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the Learn More ideal answer.

## What Does Bitcoin Mining Code Mean?

The number above has 64 digits. Easy enough to understand so far. As you likely noticed, that number consists not only of numbers, but also letters of this alphabet. Why is that

In order to understand these letters are doing in the middle of numbers, let us unpack the term"hexadecimal."

As you knowwe use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
