# Some Known Facts About Bitcoin Mining Code.

Let's say you had one legit $20 and one quite good photocopy of that same $20. If someone were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would observe that they had been the same number, and consequently one of them needed to be fictitious.

This isn't a perfect analogy--we will 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 established by Satoshi Nakamoto, and can be an issue of controversy, as some miners believe the block size should be increased to accommodate more data.

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

1MB of transactions can technically be little as 1 transaction (although this is not at all common) or several 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 work, one is a matter of luck.

2) You must be the first miner to reach the perfect answer to a numeric problem. This process is also known as an evidence of work.

The fantastic news: No advanced math or computation is involved. You may have discovered that miners are solving challenging 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") that is less than or equal 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 to have a high"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 could mine along with your mining rig's hash pace, 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--particularly Ethereum miners--buy individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photo below is a makeshift, high-tech 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.

Example: I tell three friends that I'm thinking of a number between 1 and 100, and click this site that I write that number on a piece 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 guess any number that is less than or like this equal to the number I am thinking of.

## The Single Strategy To Use For Money To Bitcoin

Let's say I am thinking of the number 19. If Friend A guesses 21, they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both theoretically arrived at viable 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 conditions, simultaneous answers occur frequently, but at 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 determine by a simple majority--51 percent --which miner to honour. Typically, it is the miner who has done the work, i.e.

The losing block then becomes an"orphan block" .

Now imagine I present the"figure what number I am thinking of" question, but I'm not asking only three friends, and I am not thinking of a number between 1 and 100. Instead, I'm asking millions of would-be miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it is going to be quite hard to guess the ideal answer.

## What Does 20000 Satoshi Do?

The number preceding has 64 digits. Easy enough to understand up to now. As you 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 us unpack the term"hexadecimal."

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