# Not known Facts About Bitcoin Mining Code

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 real bill and the imitation one, someone that took the trouble of looking at both of those bills' consecutive numbers would observe that they were exactly the exact same number, and consequently one of them had 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 is 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 eligible to earn Bitcoin--not everyone who supports transactions will receive paid off.

1MB of transactions can technically be little as 1 transaction (though 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 work, one is a matter of luck.

2) You have to be the first miner to arrive at the perfect answer to some numeric issue. 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 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: Because it's guesswork, you need a good deal of computing power in order to get there . 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 (TH/s).

If you want to estimate just how much Bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare offers 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--buy individual graphics cards our website (GPUs) as a low-cost method to cobble together mining operations.  The photo below is a makeshift, home-made mining machine.  The cards are such rectangular cubes with whirring circles.  Note the sandwich twist-ties holding the graphics cards to the metal pole.

Case in point : I tell three friends I'm thinking of 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 specific number, they simply must be the first person to guess any number that is less than or equal to this number I am thinking of.

## The 3-Minute Rule for 20000 Satoshi

Let us say I am thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both technically came at workable answers, because 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the target answer of 19. .

In Bitcoin terms, simultaneous answers happen frequently, but at 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%--which miner to honour. Normally, it is the miner who has done the most work, i.e.

The losing block then becomes an"orphan block" .

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