How Bitcoins Are Made - Truths
Let's say you had one legit $20 and one really good photocopy of the same $20. If someone were to try to spend both the true bill and the fake one, someone who took the trouble of looking at either of the bills' consecutive numbers would see that they were exactly the exact same number, and thus one of them had to be fictitious.
This isn't a great analogy--we'll explain in more detail below. .
Once a miner has confirmed 1 MB (megabyte) worth of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and is an issue of controversy, as some miners believe the block size should be increased to accommodate more information.
Note that I said that verifying 1 MB value of transactions makes a miner qualified to earn Bitcoin--not everyone who verifies transactions will receive paid out.
1MB of transactions can theoretically be as little as 1 transaction (though this is not in any way common) or several thousand. It depends on how much information the transactions consume.
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 have to be the first miner to reach the perfect answer to a numeric issue. This practice is also known as a proof of work.
The fantastic news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that's not true in any way. What they are doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") which is less than or equal to the 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 have 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 just how much Bitcoin you could mine with your mining rig's hash pace, the site Cryptocompare provides a very 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The graphics cards are such rectangular blocks 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 websites thinking of 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 need to guess the specific number, they simply have to be the very first person to guess any number that's less than or equal to the number I'm thinking of.

Let's say I am thinking about the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both theoretically arrived at workable answers, since 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 terms, simultaneous answers happen frequently, but in 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 decide by a simple majority--51%--which miner to go to the website honour. Typically, it's the miner that has done the most work, i.e.

The number preceding has 64 digits. Easy enough to understand up to now. As you likely noticed, that number consists not just of numbers, but also letters of check over here this alphabet. Why is that
In order to understand what these letters are doing in the middle of numbers, let us unpack the word"hexadecimal."
As you knowwe use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 possibilities, 0-9.
