# The Best Guide To Bitcoin Mining Code

Let us say you had one legit $20 and one really 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 trouble of looking at both of those invoices' consecutive numbers would see that they had been the exact same number, and thus one of them needed to be false.

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

Once a miner has verified 1 MB (megabyte) worth 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 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 qualified to earn Bitcoin--not everyone who verifies transactions will receive paid off.

1MB of transactions can theoretically be as small as 1 transaction (though this is not in any way common) or a few thousand. It depends on how much information the transactions consume.

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 arrive at the right 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 might have heard that miners are solving challenging mathematical problems--that is not true at all. What they are actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") which is less than or equivalent to the target hash.

The bad news: Because it's guesswork, you need a lot of computing power in order to get there first. To mine successfully, you need next to get a high"hash speed," 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 how much Bitcoin you could mine with your mining rig's hash pace, the website Cryptocompare provides a helpful calculator.

Either 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The graphics linked here cards are those 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 about 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 am thinking of.

Let us say I'm 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 have both theoretically arrived at viable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer to the goal 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 equivalent 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 number preceding 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 what 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 is base 10. This in turn means that every digit has 10 possibilities, 0-9.
