# 8 Simple Techniques For Bitcoin Mining Code

Let's say you had one legit $20 and one really 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 both of the invoices' serial numbers would observe that they were exactly the same number, and thus one of them needed to be false.

That isn't a perfect 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 an issue of controversy, as some miners believe the block size ought to be increased to accommodate more data.

Note that I said that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will receive paid off.

1MB of transactions can technically be little as 1 transaction (though this is not at all 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 must be the first miner to arrive at the right answer to some numeric problem. This practice 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'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: Since it is guesswork, you need a lot of computing power in order to get there . To mine successfully, you need to have a higher"hash speed," that is important link 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 can mine along with your mining rig's hash pace, the site Cryptocompare offers a very helpful calculator.

Either way a GPU (graphics processing unit) miner or an application-specific integrated circuit (ASIC) miner. These can run from $500 into the tens of thousands. Some miners--particularly Ethereum miners--purchase individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photograph below is a makeshift, home-made mining machine. The graphics cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal pole.

Example: I tell three friends that I'm thinking of 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 exact number, they just have to be the very first person to figure any number that's less than or equal to this number I'm thinking of.

Let's say I'm thinking about the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they've both technically came at viable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the target answer of 19. .

In Bitcoin conditions, simultaneous answers occur frequently, but in 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 decide by a simple majority--51 percent --that miner to honour. Typically, it's the miner who has done the most work, i.e.

## Excitement About How Bitcoins Are Made

The number preceding has 64 digits. Easy enough to understand up to now. As you probably noticed, that number consists not only of numbers, but also letters of the alphabet. Why is that

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

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