# Help Wikipedia for Dummies

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 true bill and the fake one, someone who took the trouble of looking at either of the invoices' serial numbers would see that they were the exact same number, and thus one of them needed to be false.

This 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 an issue of controversy, as some miners think the block size ought to be increased to accommodate more data.

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 off.

1MB of transactions can theoretically be as little as 1 transaction (although 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 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 perfect answer to a numeric problem. This process is also known as an evidence of work.

The good news: No advanced math or computation is involved. You might have heard that miners are solving difficult mathematical problems--that's 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 is 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 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 can mine 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--purchase individual graphics cards (GPUs) as a low-cost image source method to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The graphics cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

Example: 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 have to guess the exact number, they simply have to be the very first person to figure any number that is less than or equal to this number I am thinking of.

## An Unbiased View of 20000 Satoshi

Let us say I'm thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both technically came at viable answers, since 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 conditions, simultaneous answers happen frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented which can be equal to or less than the target number, the Bitcoin network will determine by a simple majority--51%--which miner to honour. Normally, 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"guess what number I am thinking of" question, but I'm not asking just 3 friends, and I'm not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I am thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard 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 this alphabet. Why is that

In order to understand what 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's base 10. This in turn means that each and every digit has 10 chances, 0-9.
