# Everything about Bitcoin Mining Code

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

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

Once a miner has verified 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 eligible 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 a few thousand. It depends on how much data the transactions consume.

In order to earn Bitcoin, you need to meet two conditions. One is a matter of work, one is a matter of luck.

2) You must be the first miner to arrive at the perfect answer to a numeric problem. This process is also known as a proof of work.

The good news: No advanced math or computation is involved. You may have heard that miners are solving challenging mathematical problems--that's not true at all. What they're actually 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: Since it's guesswork, you need a good deal of computing power in order to get there . To mine successfully, you need to have a higher"hash speed," 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 pace, the site 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. Extra resources Some miners--particularly Ethereum miners--buy individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The go to my site photograph below is a makeshift, high-tech mining machine. The graphics cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal pole.

Example: I tell three friends that 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 have to guess the specific number, they just must be the very first person to guess any number that is less than or equal to the number I'm thinking of.

Let us say I'm thinking about the number 19. If Friend A guesses 21they shed because 21>19. link If Friend B guesses 16 and Friend C guesses 12, then they've both technically came at workable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was closer 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 work, i.e.

The losing block then becomes an"orphan block" .

Now imagine that I pose the"guess 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 am asking millions of prospective miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the ideal answer.

## Not known Facts About How Bitcoins Are Made

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

In order to understand what these letters are doing in the center of numbers, let's unpack the term"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.
