# The Bitcoin Mining Code Statements

Let's say you had one legit $20 and one quite good photocopy of that same $20. If someone were to attempt to spend both the true bill and the fake one, someone who took the trouble of looking at either of the bills' consecutive numbers would observe that they had been exactly the exact same number, and thus one of them needed to be fictitious.

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

Once a miner has confirmed 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and can be 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 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 small as 1 transaction (although this is not at all common) or several thousand. It depends on how much information the transactions consume.

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 have to be the first miner to reach the right answer to a numeric problem. This practice is also known as a proof of work.

The fantastic news: No advanced math or computation is involved. You may have heard that miners are solving challenging mathematical problems--that's not true in any way. 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 hash.

The bad news: Because it is guesswork, you need a good deal of computing power in order to get there first. To mine , you need to get a higher"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 how much Bitcoin you could mine along with your mining rig's hash rate, useful reference the website 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--particularly Ethereum miners--buy individual graphics cards (GPUs) as a low-cost method to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The graphics cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal pole.

Case in point I tell three friends 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 don't need to guess the specific 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.

Let's say I am thinking of the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both technically came 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 which can be equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51%--that miner to honour. Normally, it's 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 am thinking of" question, however I'm not asking just three friends, and I'm not thinking of a number between 1 and 100. Instead, I'm asking millions of would-be miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it pop over to this site is going to be quite difficult to guess the ideal answer.

## Fascination About Bitcoin Mining Code

The number above 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 these letters are doing in the middle of numbers, let us unpack the word"hexadecimal."

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