Let's say you had one legit $20 and one quite good photocopy of the same $20. If someone were to attempt to spend both the true bill and the imitation one, someone who took the problem of looking at either of those invoices' consecutive numbers would see that they were the same number, and consequently one of them had to be false.
That isn't a perfect analogy--we will 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 is 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 value of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will receive paid out.
1MB of transactions can technically be little as 1 transaction (although this is not in any way common) or a few thousand. It depends on how much information the transactions consume.
In order to earn Bitcoin, you need to fulfill two conditions. One is a matter of work, one is a matter of luck.
2) You have to be the first miner to reach the perfect answer to a numeric issue. This process is also known as a proof of work.
The good news: No advanced math or computation is involved. You may 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 hash.

The bad news: Because it's 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 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 provides a helpful calculator.
Either way 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 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 graphics cards into the metal pole.
Case in point I tell three friends that I'm thinking about a number between 1 and 100, and I write that number on a sheet of paper and seal it in an envelope. My friends don't have to guess the specific number, they just must be the first person to figure any number that is less than or equal to the number I'm thinking of.
What Does 20000 Satoshi Mean?
Let us say I am thinking about the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they've both technically came at viable answers, since 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was closer 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 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%--which miner to honour. Typically, it is the miner who has done the most 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 this 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 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.
