# Some Ideas on Help Wikipedia You Should Know

Let's say you had one legit $20 and one quite good photocopy of that same $20. If someone were to try to spend both the real bill and the fake one, someone that took the problem of looking at both of the invoices' consecutive numbers would see that they were exactly the same number, and thus one of them had 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 entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and can be a matter of controversy, as some miners think 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 supports transactions will get paid out.

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

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 must be the first miner to reach the perfect answer to a numeric issue. This process 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 difficult 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 equivalent to the target 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 have a higher"hash rate," which is quantified 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 with your mining rig's hash pace, the website Cryptocompare offers a 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photograph 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 rod.

Case in point I tell three friends 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 navigate to this site envelope. My friends don't have to guess the exact number, they simply must be the first person to guess any number that is less than or equal to this number I am thinking of.

Let us say I am thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C supposes 12, then browse around here they've both theoretically arrived at workable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer 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 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%--that miner to honour. Normally, it's the miner that has done the work, i.e.

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

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

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 the alphabet. Why is that

In order to understand what these letters are doing in the center of numbers, let us unpack the word"hexadecimal."

As you know, we utilize the"decimal" system, which you can look here means it is base 10. This in turn means that every digit has 10 possibilities, 0-9.
