The Facts About 20000 Satoshi Revealed

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 real bill and the imitation one, someone who took the trouble of looking at both of the invoices' consecutive numbers would observe that they had been the exact same number, and consequently one of them needed to be fictitious.

That isn't a perfect analogy--we will 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 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 stated that verifying 1 MB value of transactions makes a miner qualified to earn Bitcoin--not everyone who verifies transactions will receive paid out.

1MB of transactions can technically be small as 1 transaction (though 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 meet two conditions. One is a matter of effort, one is a matter of luck.

2) You must be the first miner to reach the right answer to some numeric issue. This practice is also known as a proof of work.

The good news: No advanced math or computation is involved. You might 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")  which is less than or equal to the target 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 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 along with your mining rig's hash rate, the site 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 to the tens of thousands.  Some miners--especially Ethereum miners--buy 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 pictures cards to the metal rod.

ExampleI tell three friends that 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 just have to be the first person to figure any number that's less than or equal to this number I am thinking of.

Let's say I am 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've both technically came at viable 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 in the end of the day there can only be one winning answer. When multiple simultaneous answers are presented which can be equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--that miner to honour. Normally, it is the miner who has done the most work, i.e.

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

Now imagine I present the"figure what number I am see thinking of" question, but I am not asking just three friends, and I'm not thinking of a number between 1 and 100. Instead, I am asking millions of prospective miners and I am thinking about 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 these letters my response are doing in the center of numbers, let us unpack the word"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.
