# The smart Trick of Help Wikipedia That Nobody is Discussing

Let us say you had one legit \$20 and one really good photocopy of that same \$20. If someone were to try to spend both the true bill and the fake one, someone who took the trouble of looking at both of those invoices' consecutive numbers would observe that they had been exactly the exact same number, and consequently one of them needed to be false.

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

Once a miner has confirmed 1 MB (megabyte) worthiness 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 believe the block size ought to 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 theoretically be as little as 1 transaction (although this is not at all common) or several thousand. It depends on how much information 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 perfect answer to a numeric problem. 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 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")  that is less than or equivalent to the hash.

The bad news: Because it's guesswork, you need a good deal of computing power in order to get there . To mine , you need to get a high"hash rate," which is quantified 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 could mine with your mining rig's hash rate, the site Cryptocompare offers 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--particularly 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 are those rectangular blocks with whirring circles.  Note the sandwich twist-ties holding the pictures cards into the metal rod.

Example: I tell three friends I'm thinking of a number between 1 and 100, and that I write that number on a piece of paper and seal it in an envelope. My friends don't need to guess the specific number, they just must be the very first person to guess any number that's less than or equal to the number I am thinking of.

Let us 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 have 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 nearer to the goal 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 which can be equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --which 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 I pose the"figure what number I'm thinking of" question, but I'm not asking just 3 friends, and I'm not thinking of a number between 1 and 100. Instead, I'm 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 extremely hard to guess the right 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 center of numbers, let us unpack the term"hexadecimal."

As you know, we look at this website use the"decimal" system, which means it's base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
