# What Does How Bitcoins Are Made Do?

Let us say you had one legit \$20 and one quite good photocopy of the 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 either of those bills' serial numbers would see that they were the same number, and thus one of them needed to be fictitious.

This isn't a great analogy--we will explain in more detail below. .

Once a miner has verified 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 should be increased to accommodate more information.

Note that I said that verifying 1 MB value of transactions makes a miner eligible 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 information 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 reach the right answer to a numeric problem. This process is also known as a proof of work.

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

The bad news: Since it is guesswork, you need a good deal of computing power in order to get there first. To mine , 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 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 a GPU (graphics processing unit) official source 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 cheap way to cobble together mining operations.  The photograph below is a makeshift, home-made mining machine.  The cards are those rectangular blocks with whirring circles.  Note the sandwich twist-ties holding the graphics cards to the metal rod.

Example: I tell three friends I'm thinking of a number between 1 and 100, and that 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 must be the first person to figure any number that's less than or equal to the number I am thinking of.

## The 5-Minute Rule for How Bitcoins Are Made

Let us say I am thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they have 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 closer to the target 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 which can be equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --that miner to honour. Typically, it is the miner that has done the most work, i.e.

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

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

## The 6-Minute Rule for Money To Bitcoin

The number above has 64 digits. Easy enough to understand up to now. As you likely noticed, that number consists not only of numbers, but also letters of the alphabet. Why is that

In order to understand these letters are doing in the center of numbers, let's unpack the word"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.
