# The 2-Minute Rule for How Bitcoins Are Made

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 true bill and the fake one, someone who took the problem of looking at either of the bills' consecutive numbers would observe that they were exactly the same number, and consequently one of them needed 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 eligible 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 believe 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 get paid out.

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

In order to earn Bitcoin, you need to meet two conditions. One is a matter of work, one is a matter of luck.

2) You must be the first miner to reach the right answer to some 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 discovered that miners are solving difficult 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 equivalent to the target hash.

The bad news: Since it's guesswork, you need a good deal of computing power in order to get there . To mine , you need to get 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 how much Bitcoin you can mine along 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--especially Ethereum miners--buy 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 such rectangular blocks with whirring circles. Note the look at more info sandwich twist-ties holding the pictures cards into the metal pole.

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

Let's say I am 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 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 goal answer of 19. .

In Bitcoin terms, 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 equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --which miner to honour. Typically, it's the miner who has done the work, i.e.

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

Now imagine that I present the"figure what number I'm thinking of" question, but I am not asking only 3 friends, and I am not thinking of a number between 1 and 100. Rather, I'm asking millions of would-be miners and I am thinking about a 64-digit hexadecimal number. Now you see that it is going to be quite difficult to guess the ideal answer.

The number preceding has 64 digits. Easy find 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 these letters are doing in the middle of numbers, let's unpack the term"hexadecimal."

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