How Bitcoins Are Made Fundamentals Explained
Let us say you had one legit $20 and one really good photocopy of the same $20. If someone were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of those bills' serial numbers would observe that they had been the exact same number, and thus one of them needed to be fictitious.
That 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 eligible to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and can be an issue of controversy, as some miners think the block size should be increased to accommodate more data.
Note that I said that verifying 1 MB value 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 (although 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 must be the first miner to arrive at the perfect 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 may have heard that miners are solving challenging mathematical problems--that's not true at all. What they're 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.

The bad news: Because it's guesswork, you need a good deal of computing power in order to get there first. To mine successfully, you need to get a higher"hash rate," 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 how much Bitcoin you could mine along with your mining rig's hash rate, 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 to 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 cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal rod.
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 sheet of paper and seal it in an envelope. My friends don't have to guess the exact number, they just have to be the very first person to figure any number that's less than or equal to this number I'm thinking of.

Let us say I am thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B guesses 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 nearer to the goal answer of 19. .
In Bitcoin terms, simultaneous answers happen frequently, but at the end of the day there can this link 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. Normally, it's the miner that has done the most work, i.e.

The number above has 64 digits. Easy enough to understand up to now. As you probably noticed, that number check it out consists not just of numbers, but also letters of this alphabet. Why is that
In order to understand what these letters are doing in the center of numbers, let's unpack the term"hexadecimal."
As great post to read you know, we utilize the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
