# Money To Bitcoin - An Overview

Let's say you had one legit $20 and one really good photocopy of the same $20. If someone were to try to spend both the real bill and the fake one, someone who took the problem of looking at either of those invoices' serial numbers would observe that they had been exactly the same number, and consequently one of them needed to be fictitious.

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

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

Note that I stated that verifying 1 MB worth of transactions makes a miner qualified to earn Bitcoin--not everyone who verifies transactions will receive paid out.

1MB of transactions can technically be 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 reach the perfect answer to a numeric issue. This process is also known as an evidence of work.

The fantastic news: No advanced math or computation is involved. You might 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") which is less than or equivalent to the target hash.

The bad news: Because it is guesswork, you need a lot of computing power in order to get there first. 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 could mine along with your mining rig's hash pace, the site Cryptocompare provides 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--particularly Ethereum miners--purchase individual graphics cards (GPUs) as a cheap method to cobble together mining operations. look at here The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal rod.

Example: I tell three friends I'm thinking about 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 exact number, they simply must be the first person to guess any number that's less than or equal to the number I am thinking of.

## A Biased View of Bitcoin Mining Code

Let's say I'm 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 workable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .

In Bitcoin conditions, simultaneous answers happen frequently, go to website but in 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 target number, the Bitcoin network will determine by a simple majority--51 percent --which miner to honour. Normally, it's the miner who has done the work, i.e.

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

Now imagine that I pose the"guess what number I'm thinking of" question, but I am not asking just three friends, and I'm not thinking of a number between 1 and 100. Rather, I am asking millions of prospective miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it is going to be quite hard to guess the right answer.

## Some Known Factual Statements About 20000 Satoshi

The number preceding has 64 digits. Easy enough to understand so far. As you likely noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that

In order to understand these letters are click doing in the middle of numbers, let us unpack the word"hexadecimal."

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