# Getting The Help Wikipedia To Work

Let us say you had one legit \$20 and one really good photocopy of the same \$20. If someone were to attempt to spend both the true bill and the imitation one, someone that took the trouble of looking at both of the bills' consecutive numbers would observe that they had been exactly the exact same number, and consequently one of them needed to be false.

That isn't a perfect analogy--we'll 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 established by Satoshi Nakamoto, and can be 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 worth of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid out.

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

In order to earn Bitcoin, you need to fulfill 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 right answer to some numeric issue. This process is also known as an evidence of work.

The fantastic news: No advanced math or computation is involved. You may have heard that miners are solving challenging mathematical problems--that is not true in any way. What they are 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 target hash.

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

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

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 exact number, they just have to be the first person to guess any number that's less than or equal to this number I am thinking of.

Let's say I'm thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they've both theoretically arrived 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 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 determine by a simple majority--51%--which miner to honour. Normally, it is the miner that has done the most work, i.e.

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

Now imagine that I present the"guess what number I'm thinking of" question, however I'm not asking only three friends, and I am not thinking of a number between 1 and 100. Rather, I am asking millions of would-be try these out 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 preceding has 64 digits. Easy enough to understand up to now. As you probably noticed, that number consists not just 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's unpack the term"hexadecimal."

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