# The Basic Principles Of Money To Bitcoin

Let's 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 imitation one, someone who took the trouble of looking at both of the bills' consecutive numbers would see that they had been 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 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 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 worth of transactions makes a miner qualified to earn Bitcoin--not everyone who supports transactions will receive paid off.

1MB of transactions can technically be small 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 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 issue. This process is also known as an evidence of work.

The good news: No advanced math or computation is involved. You might have heard that miners are solving difficult mathematical problems--that's not true in any way. What they're doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") which is less than or equal to the hash.

The bad news: Since it's guesswork, you need a lot of computing power in order to get there . To mine , you need to have a high"hash rate," 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 could mine along with your mining rig's hash rate, the website Cryptocompare provides 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 low-cost way to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

ExampleI tell three friends I'm thinking about a number between 1 and 100, and 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 first person to figure any number that is less than or equal to this number I am thinking of.

Let's say I'm thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend Resources B supposes 16 and Friend C guesses 12, then they have 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 conditions, simultaneous answers happen 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 target number, the Bitcoin network will decide by a simple majority--51 percent --which miner to honour. Typically, it's the miner who has done the work, i.e.

The losing block then becomes an"orphan block" .

Now imagine that I present the"figure what number I'm thinking of" question, but 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 prospective miners and I am thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely difficult to guess the ideal answer.

## The 4-Minute Rule for Bitcoin Mining Code

The number preceding has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not only 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 utilize the"decimal" system, which means it's base 10. This in turn means that each and every digit has 10 chances, 0-9.
