# What Does How Bitcoins Are Made Mean?

Let us say you had one legit $20 and one quite 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 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 great analogy--we will 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 set by Satoshi Nakamoto, and is an issue of controversy, as some miners think 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 off.

1MB of transactions can theoretically be as small as 1 transaction (though this is not at all common) or a few thousand. It depends on how much data 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 have to be the first miner to arrive at the perfect answer to a numeric problem. This practice is also known as a proof 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're doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the target hash.

The bad news: Since it's guesswork, you need a lot of computing power in order to get there first. To mine , you need to get a high"hash rate," which 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 with your mining rig's hash rate, the site Cryptocompare provides 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--especially Ethereum miners--buy 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 blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to 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 envelope. My friends don't need to guess the exact number, they simply have to be the first person to guess any number that is less than or equal to this number I am thinking of.

Let's say I am thinking about 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 technically came at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the goal answer of 19. .

In Bitcoin conditions, simultaneous answers happen frequently, but in 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 percent --that miner to honour. Typically, it's the miner that has done the work, i.e.

The losing block then becomes an"orphan block" .

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

The number preceding 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 term"hexadecimal."

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