How Bitcoins Are Made for Beginners
Let's say you had one legit $20 and one quite 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 problem of looking at either of the invoices' consecutive numbers would observe that they were the exact same number, and thus one of them had to be false.
This 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 set by Satoshi Nakamoto, and is an issue of controversy, as some miners think the block size should be increased to accommodate more information.
Note that I stated that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will get paid out.
1MB of transactions can technically be small as 1 transaction (although this is not in any way common) or several thousand. It depends on how much data 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 some numeric problem. This practice is also known as an evidence of work.
The fantastic news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that is not true at all. What they are doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") which is less than or equal to the hash.

The bad news: Since it is guesswork, you need a lot of computing power in order to get there first. To mine , you need to have a higher"hash speed," Continue 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 how much Bitcoin you could mine along with your mining rig's hash pace, the site 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 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 photo below is a makeshift, high-tech mining machine. The cards Discover More are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards into the Extra resources metal rod.
ExampleI tell three friends I'm thinking of 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 exact number, they simply have to be the first person to guess any number that is less than or equal to the number I'm thinking of.

Let's say I'm thinking about the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both technically came 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 at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equal to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --which miner to honour. Normally, it's the miner who has done the work, i.e.

The number above 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 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's base 10. This in turn means that every digit has 10 chances, 0-9.
