# What Does 20000 Satoshi Do?

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 true bill and the fake one, someone that took the problem of looking at both of the bills' consecutive numbers would observe that they had been the exact same number, and thus one of them had to be fictitious.

That isn't a perfect analogy--we will explain in more detail below. .

Once a miner has confirmed 1 MB (megabyte) worth of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was established 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 value of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid out.

1MB of transactions can theoretically be as small as 1 transaction (although this is not at all 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 have to be the first miner to reach the right answer to some numeric problem. This process 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 difficult mathematical problems--that's not true in any way. What they are 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: Because it's guesswork, you need a lot of computing power in order to get there first. To mine successfully, you need to get 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 can mine along with your mining rig's hash pace, the website Cryptocompare offers 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--particularly 20000 Satoshi Ethereum miners--buy 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 are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal rod.

Example: I tell three friends that I'm thinking of click to read more 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 specific number, they simply must be the very first person to figure any number that's less than or equal to this number I'm thinking of.

## Fascination About 20000 Satoshi

Let's say I am thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they have both theoretically arrived at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the target answer of 19. .

In Bitcoin conditions, simultaneous answers occur frequently, but at 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 like this determine by a simple majority--51%--that miner to honour. Normally, it is the miner that has done the work, i.e.

The losing block then becomes an"orphan block." .

Now imagine that I present the"guess what number I'm thinking of" question, however I am not asking only three friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I am thinking of a 64-digit hexadecimal number. Now you see that it's going to be quite difficult to guess the ideal answer.

The number above has 64 digits. Easy enough to understand up to now. As you probably 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's unpack the term"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 chances, 0-9.
