# Bitcoin Mining Code for Beginners

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

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

Once a miner has confirmed 1 MB (megabyte) worth of Bitcoin transactions, they are eligible 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 stated that verifying 1 MB worth of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will get paid off.

1MB of transactions can technically be small as 1 transaction (though this is not in any way common) or several thousand. It depends on how much data the transactions take up.

In order to earn Bitcoin, you need to fulfill 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 perfect answer to a numeric issue. This practice 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 challenging mathematical problems--that is not true at all. 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 target 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 rate," that 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 just how much Bitcoin you can mine along with your mining rig's hash pace, the website Cryptocompare offers 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. get redirected here The cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal pole.

Example: 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 exact number, they simply have to be the very first person to guess any number that's less than or equal to the number I'm thinking of.

Let us say I am 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've both theoretically arrived at workable answers, since 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 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 equal to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --that miner to honour. Normally, it's the miner that has done the most work, i.e.

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

Now imagine I pose the"figure what number I'm thinking of" question, however I'm not asking just 3 friends, and I'm not thinking of a number between 1 and 100. Instead, I'm asking millions of prospective miners and I am thinking about a 64-digit hexadecimal number. Now you see that it's going to be extremely difficult to guess the right answer.

## 4 Simple Techniques For How Bitcoins Are Made

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 the alphabet. Why is that

In order to understand these letters are doing in the middle 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 each and every digit has 10 possibilities, 0-9.
