# 20000 Satoshi - Truths

Let us say you had one legit $20 and one really good photocopy of the same $20. If someone were to attempt to spend both the true bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would observe that they were the same number, and thus one of them needed to be false.

This isn't a great analogy--we'll explain in more detail below. .

Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and is a matter of controversy, as some miners think the block size should be increased to accommodate more information.

Note that I said that verifying 1 MB worth of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will get paid out.

1MB of transactions can theoretically be as little as 1 transaction (though this is not in any way common) or a few thousand. It depends on how much information 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 arrive at the perfect answer to some numeric issue. This practice is also known as an evidence of work.

The good news: No advanced math or computation is involved. You may have discovered that miners are solving challenging 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") that is less than or equal to the target hash.

# The 7-Minute Rule for 20000 Satoshi

The bad news: Since it's guesswork, you need a good deal of computing power in order to get there first. To mine , you need to have a high"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 how much Bitcoin you can mine with your mining rig's hash rate, the site Cryptocompare offers a 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 low-cost way to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The cards are such rectangular cubes 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 here don't need to guess the exact number, they just have to be the first person to figure any number that is less than or equal to this number I am thinking of.

## Everything about 20000 Satoshi

Let's say I'm thinking of the number 19. If Friend A guesses 21they shed because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they've both theoretically arrived at workable answers, since 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the goal 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 that are equal to or less than the look at here target number, the Bitcoin network will determine by a simple majority--51 percent --that miner to honour. Typically, it is the miner who has done the most work, i.e.

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

Now imagine I pose the"figure what number I'm thinking of" question, but I'm not asking only 3 friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer.

## Getting My How Bitcoins Are Made To Work

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's unpack the word"hexadecimal."

As you know, we use the"decimal" system, which means it is base 10. This in turn means that each and every digit has 10 chances, 0-9.
