# How Bitcoins Are Made Fundamentals Explained

Let's 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 imitation one, someone that took the trouble of looking at both of the invoices' serial numbers would see that they had been exactly the same number, and consequently one of them needed to be fictitious.

This 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 eligible to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size should be increased to accommodate more information.

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

1MB of transactions can technically be little as 1 transaction (although this is not at all common) or a few thousand. It depends on how much data 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 must 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 fantastic news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems--that's not true at all. What they're actually doing is trying to be the first miner to come up with a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the target hash.

The bad news: Because it is guesswork, you need a lot of computing power in order to get there first. To mine successfully, you need to have a high"hash rate," that is quantified in terms of megahashes per second (MH/s), gigahashes per second (GH/s), and terahashes per second check here (TH/s).

If you want to estimate how much Bitcoin you could mine along with your mining rig's hash rate, the site Cryptocompare provides 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a low-cost way to cobble together mining operations. The photo 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 graphics cards into the metal rod.

ExampleI 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 simply must be the first person to figure any number that is less than or equal to this number I'm thinking of.

## The How Bitcoins Are Made Ideas

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 technically came 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 conditions, simultaneous answers happen frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are 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.

## Unknown Facts About Bitcoin Mining Code

The number above dig this has 64 digits. Easy enough to understand up to now. As you straight from the source likely noticed, that number consists not only of numbers, but also letters of this alphabet. Why is that

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

As you know, we utilize the"decimal" system, which means it is base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
