# The Help Wikipedia PDFs

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 imitation one, someone that took the problem of looking at either of those bills' consecutive numbers would observe that they had been exactly the exact same number, and thus one of them had to be false.

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

Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and is an issue 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 value of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will get paid out.

1MB of transactions can theoretically be as small as 1 transaction (although 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 fulfill 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 process is also known as a proof of work.

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

The bad news: Since it is guesswork, you need a good deal 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 how much Bitcoin you can mine along with your mining rig's hash pace, the website 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 to the tens of thousands. Some miners--particularly Ethereum miners--purchase 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 cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.

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

Let us say I'm thinking of the number 19. If Friend A guesses 21they shed because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have 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 closer to the target answer of 19. .

In Bitcoin conditions, simultaneous answers occur frequently, but in the end of the day there can only be one winning more answer. When multiple simultaneous answers are presented that are equivalent to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --which miner to honour. Typically, it is the miner that has done the most work, i.e.

## How Bitcoins Are Made - The Facts

The number preceding has 64 digits. Easy enough straight from the source to understand up to now. As you likely noticed, that number consists not just of click to investigate 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 utilize the"decimal" system, which means it's base 10. This in turn means that every digit has 10 possibilities, 0-9.
