What Does 20000 Satoshi Mean?
Let's say you had one legit $20 and one really good photocopy of that same $20. If someone were to attempt to spend both the real bill and the fake one, someone that took the problem of looking at both of those invoices' serial numbers would see that they had been exactly the exact same number, and consequently one of them had to be false.
This 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 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 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 supports transactions will receive paid off.
1MB of transactions can technically be little as 1 transaction (although this is not in any way common) or a few thousand. It depends on how much data the transactions take up.
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 must be the first miner to arrive at the right answer to some numeric issue. This process is also known as an evidence of work.
The fantastic 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 hash.

The bad news: Since it is 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 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 can mine along with your mining rig's hash rate, the website Cryptocompare provides a helpful calculator.
Either way a GPU (graphics processing unit) miner or an application-specific integrated have a peek at these guys circuit (ASIC) miner. These can run from $500 to the tens of thousands. Some miners--particularly Ethereum miners--purchase individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.
ExampleI tell three friends I'm thinking about a number between 1 and 100, and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the specific number, they simply have to be the first person to figure any number that's less than or equal to this number I am thinking of.

Let us 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 have 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 closer to the goal 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 that are equivalent to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --that miner to honour. Typically, it is the miner that has done the 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 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 each and every digit has 10 possibilities, 0-9.
