Getting My How Bitcoins Are Made To Work
Let's 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 both of the invoices' consecutive numbers would observe that they were the same number, and consequently one of them needed to be fictitious.
That 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 eligible 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 believe the block size should be increased to accommodate more data.
Note that I said that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will receive paid off.
1MB of transactions can theoretically be as small as 1 transaction (though this is not at all common) or several thousand. It depends on how much data the transactions take up.
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 issue. This practice is also known as an evidence of work.
The fantastic news: No advanced math or computation is involved. You might have heard that miners are solving difficult mathematical problems--that is 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 equal 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 successfully, you need to get 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 how much Bitcoin you can mine with your mining rig's hash rate, the website Cryptocompare offers a helpful calculator.
Either way a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from $500 into the tens of thousands. Some miners--particularly Ethereum miners--buy individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal pole.
ExampleI tell three friends that I'm thinking about a number between 1 and 100, and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number, they simply have to be the first person to figure any number that is less than or equal to the number I am thinking of.

Let us say I'm thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both technically came at workable answers, because 16<19 and 12<19. There original site is no"extra credit" for Friend B, even though B's answer was nearer to the target answer of 19. .
In Bitcoin conditions, simultaneous answers occur 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 is the miner who has done the work, i.e.

The number preceding has 64 digits. Easy enough to understand so far. As you likely noticed, that number consists not just 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 us 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 chances, 0-9.
