Let's say you had one legit $20 and one really good photocopy of the same $20. If someone were to attempt to spend both the true bill and the imitation one, someone that took the problem of looking at both of the bills' serial numbers would observe that they were the exact same number, and thus one of them had to be false.
This isn't a great analogy--we'll explain in more detail below. .
Once a miner has verified 1 MB (megabyte) worth of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners think the block size should be increased to accommodate more information.
Note that I said that verifying 1 MB worth of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will receive paid out.
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 a 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 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 hash.

The bad news: Since it's guesswork, you need a lot of computing power in order to get there . To mine successfully, you need to have 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 just how much Bitcoin you could mine along with your mining rig's hash pace, the site 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--purchase individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photo below is a makeshift, home-made mining machine. The cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal pole.
Case in point I tell three friends I'm thinking of a number between 1 and 100, and I write that view number on a piece of image source paper and seal it in an envelope. My friends don't have to guess the exact number, they simply must be the very first person to figure pop over to these guys any number that's less than or equal to the number I am thinking of.

Let's say I am thinking about 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 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 occur 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 determine by a simple majority--51%--that miner to honour. Normally, it is the miner that has done the most work, i.e.

The number above has 64 digits. Easy 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 what 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 each and every digit has 10 chances, 0-9.
