# 3 Easy Facts About Bitcoin Mining Code Described

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 that took the trouble of looking at either of those bills' consecutive numbers would see that they had been exactly the same number, and consequently one of them needed 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 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 should be increased to accommodate more data.

Note that I stated that verifying 1 MB value 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 small as 1 transaction (though this is not at all 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 effort, one is a matter of luck.

2) You have to be the first miner to arrive at the right answer to some numeric issue. This practice is also known as a proof of work.

The good news: No advanced math or computation is involved. You may have discovered 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") which is less than or equal to the target 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 high"hash rate," 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 how much Bitcoin you could mine along with your mining rig's hash rate, the site Cryptocompare offers a helpful calculator.

Either 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--particularly Ethereum miners--buy individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal rod.

Case in point : I tell three friends that I'm thinking about a number between 1 and 100, and I write that number on a sheet of paper and seal it in an envelope. My friends don't need to guess the exact number, they just have to be the first person to figure any number that is less than or equal to this number I am thinking of.

Let us say I am thinking of the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they have both theoretically arrived at workable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .

In Bitcoin terms, simultaneous answers happen frequently, but at 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%--that miner company website to honour. Typically, it is the miner who has done the work, i.e.

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

Now imagine I present the"guess what number I'm thinking of" question, however I am not asking just 3 friends, and I'm not thinking of a number between 1 and 100. Rather, I'm asking millions of prospective miners and I am thinking of a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the right answer.

## The Ultimate Guide To How Bitcoins Are Made

The number preceding 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 these letters are doing in the middle of numbers, let us unpack the term"hexadecimal."

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