# Bitcoin Mining Code Can Be Fun For Anyone

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

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

Once a miner has confirmed 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 can be a matter of controversy, as some miners think the block size should be increased to accommodate more information.

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

1MB of transactions can technically be little as 1 transaction (though this is not at all common) or a few 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 arrive at the perfect answer to a 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 challenging mathematical problems--that is not true at all. What they are actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") that is less than or equal to the hash.

The bad news: Because it's guesswork, you need a good deal of computing power in order to get there first. To mine successfully, you need to get a high"hash rate," which is measured in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and about his terahashes per second (TH/s).

If you want to estimate how much Bitcoin you can 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 can run from $500 into the tens of thousands. Some miners--especially Ethereum miners--buy individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photo below is a makeshift, home-made mining machine. The cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal rod.

Example: I tell three friends I'm thinking about 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 have to guess the exact number, they just have to be the first person to guess any number that is less than or equal to the number I'm thinking of.

## The Bitcoin Mining Code Ideas

Let's say I am thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 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 closer 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 equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --which miner to honour. Typically, it's the miner that has done the most work, i.e.

The losing block then becomes an"orphan block" .

Now imagine that I pose the"figure what number I'm thinking of" question, however I'm not asking just 3 friends, and I'm not thinking of a number between 1 and 100. look what i found Rather, I'm asking millions of prospective miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be quite difficult to guess the ideal answer.

## Getting My How Bitcoins Are Made To Work

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 the alphabet. Why is that

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

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