About How Bitcoins Are Made
Let us say you had one legit $20 and one quite 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 problem of looking at either of the invoices' consecutive numbers would observe that they were the exact same number, and thus one of them needed to be fictitious.
This isn't a great analogy--we will explain in more detail below. .
Once a miner has confirmed 1 MB (megabyte) worthiness of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and can be an issue of controversy, as some miners believe the block size should be increased to accommodate more data.
Note that I said 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 theoretically be as little as 1 transaction (although this is not in any way common) or several thousand. It depends on how much information 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 perfect answer to a numeric problem. This practice is also known as a proof of work.
The fantastic news: No advanced math or computation is involved. You might have heard that miners are solving challenging 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 target hash.
The Basic Principles Of How Bitcoins Are Made
The bad news: Since it's guesswork, you need a good deal of computing power in order to get there first. To mine successfully, you need to have a high"hash rate," that 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 how much Bitcoin you could mine along with your mining rig's hash pace, the website 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--buy individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal rod.
Case in point I tell three friends 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 need to guess the specific number, they just must be the very first person to figure any number that's less than or equal to this number I'm thinking of.
What Does Help Wikipedia Mean?
Let us say I am thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they have directory both technically came at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the target answer of 19. .
In Bitcoin terms, simultaneous answers occur frequently, but at 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 decide by a simple majority--51%--which miner to honour. Normally, 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 probably 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 click reference middle of numbers, let's unpack the term"hexadecimal."
As you know, we use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
