Excitement About How Bitcoins Are Made
Let us say you had one legit $20 and one really good photocopy of that same $20. If someone were to attempt to spend both the real bill and the fake one, someone who took the trouble of looking at either of the bills' serial numbers would see that they had been exactly the exact 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) worthiness of Bitcoin transactions, they are entitled 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 think the block size should be increased to accommodate more data.
Note that I said that verifying 1 MB worth of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid out.
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 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 must be the first miner to arrive at the perfect answer to some numeric problem. This practice is also known as an evidence 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 in any way. What they're 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 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 could mine along with your mining rig's hash pace, the site Cryptocompare provides a very helpful calculator.
Either 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 check my site a cheap method to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal pole.
Case in point I 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 an envelope. My friends don't need to guess the specific number, they simply must be the first person to guess any number that's less than or equal to the number I'm thinking of.

Let us say I am thinking of the number 19. If Friend A guesses 21they shed because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they've both theoretically arrived at viable 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 conditions, simultaneous answers occur frequently, but at the end of the day there can only be one additional resources 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 percent --that miner to honour. Typically, it's the miner who has done the most work, i.e.
The losing block then becomes an"orphan block" .
Now imagine I pose the"figure what number I am thinking of" question, but I'm not asking just 3 friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I'm 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 above has 64 digits. Easy enough to understand up to now. As you probably 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 term"hexadecimal."
As you know, we utilize the"decimal" system, which means it is base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
