The Of Money To Bitcoin
Let's 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 problem of looking at both of the bills' serial numbers would see that they had been exactly the same number, and consequently 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) worth 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 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 supports transactions will get paid off.
1MB of transactions can theoretically be as little as 1 transaction (although this is not in any way common) or a few thousand. It depends on how much data the transactions consume.
In order to earn Bitcoin, you need to meet 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 right answer to some numeric problem. This practice is also known as an evidence of work.
The fantastic news: No advanced math or computation is involved. You might have discovered that miners are solving challenging 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 equal 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 , you need to get a high"hash speed," 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 along with your mining rig's hash pace, the site Cryptocompare offers a very 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) find more information as a cheap way to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.
ExampleI tell three friends that I'm thinking about a number between 1 and 100, and that I write that number on a piece of paper and seal it in look at more info an envelope. My friends don't have to guess the specific number, they just have to be the very first person to guess any number that is less than or equal to the number I'm thinking of.

Let us 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've both technically came at workable 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 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 that are equivalent to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Typically, it is the miner who has done the most work, i.e.
The losing block then becomes an"orphan block" .
Now imagine that I pose the"figure what number I'm thinking of" question, but I am not asking only three friends, and I am not thinking of a number between 1 and 100. Rather, I am asking millions of would-be miners and I am thinking of a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the ideal answer.
How Bitcoins Are Made for Beginners
The number preceding has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not only of numbers, but also letters of this alphabet. Why is that
In order to understand these letters are doing in the center 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 every digit has 10 chances, 0-9.
