# Getting The Bitcoin Mining Code To Work

Let us 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 those invoices' serial numbers would see that they had been exactly the exact same number, and thus one of them had to be false.

This 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 entitled to win the 12.5 BTC. The 1 MB limit was established by Satoshi Nakamoto, and can be a matter of controversy, as some miners think the block size ought to be increased to accommodate more information.

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

1MB of transactions can technically be small 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 meet two conditions. One is a matter of effort, one is a matter of luck.

2) You have to be the first miner to arrive at the perfect answer to some numeric problem. This practice is also known as an evidence of work.

The good news: No advanced math or computation is involved. You might have discovered that miners are solving challenging mathematical problems--that's not true at all. What they're 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 good deal of computing power in order to get there first. To mine successfully, you need to get a higher"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 how much Bitcoin you can mine along with your mining rig's hash rate, the site Cryptocompare provides a very 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--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 cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.

Case in point I tell three friends that I'm thinking of a number between 1 and 100, and I write that number on a sheet go of paper and seal it in an envelope. My friends don't have to guess the exact number, they just must be the very first person to figure any number that's less than or equal to this number I'm thinking of.

Let us say I'm thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they have both theoretically arrived at viable answers, because 16<19 and 12<19. There is no"extra click now 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 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 determine by a simple majority--51 percent --which miner to honour. Typically, it's the miner that has done the most work, i.e.

## The 2-Minute Rule for Money To Bitcoin

The number above has 64 digits. Easy enough to understand up to now. As you likely noticed, that number consists not just 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 word"hexadecimal."

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