Let's say you had one legit $20 and one quite 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 both of the bills' consecutive numbers would see that they were exactly the same number, and consequently one of them had to be fictitious.
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 entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is an issue of controversy, as some miners believe the block size should 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 verifies transactions will get paid off.
1MB of transactions can technically be little as 1 transaction (though this is not in any way 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 work, one is a matter of luck.
2) You must be the first miner to arrive at the right answer to some numeric problem. This practice is also known as a proof of work.
The good 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 are actually doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the target hash.
Some Known Details About Bitcoin Mining Code
The bad news: Because it's guesswork, you need a lot of computing power in order to get there . To mine , you need to get a higher"hash rate," 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 website Cryptocompare provides a 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The graphics cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal pole.
Case in point I tell three friends 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 very first person to guess any number that is less than or equal to the number I am thinking of.

Let's 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've both technically came 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 target answer of 19. .
In Bitcoin conditions, simultaneous answers happen website here 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%--which miner to honour. Typically, it is the miner who has done the work, i.e.

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 this alphabet. Why is that
In order to understand these letters are doing in the center of numbers, let us unpack the word"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.
