# The smart Trick of Bitcoin Trading History That Nobody is Talking About

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 imitation one, someone who took the trouble of looking at either of those invoices' serial numbers would observe that they had been the exact same number, and consequently one of them had to be false.

That isn't a great 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 is a matter of controversy, as some miners think the block size should be increased to accommodate more data.

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

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

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 right 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 might have discovered that miners are solving difficult mathematical problems--that is not true in any way. 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 equivalent to the hash.

# Not known Details About Bitcoin Mining Code

The bad news: Because it's guesswork, you need a lot of computing power in order to get there . To mine successfully, you need to get 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 can mine with your mining rig's hash pace, the website Cryptocompare provides a helpful calculator.

Either way 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 cheap method to cobble together mining operations. The photo check my blog below is a makeshift, high-tech mining machine. The graphics cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.

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 piece of paper and seal it in an envelope. My friends don't have to guess the specific number, they just must be the first person to figure any number that's less than or equal to the number I'm thinking of.

## The Definitive Guide to Bitcoin Mining Code

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

In Bitcoin conditions, simultaneous like it 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 equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51%--that miner to honour. Typically, it's the miner who has done the work, i.e.

The losing block then becomes an"orphan block" .

Now imagine I pose the"figure what number I am thinking of" question, however I'm not asking just 3 friends, and I'm not thinking of a number between 1 and 100. Instead, I am asking millions of prospective miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the ideal answer.

The number preceding has 64 digits. Easy enough to understand up to now. As you probably noticed, that number consists not only of numbers, but also letters of this 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 knowwe use the"decimal" system, which means it is base 10. This in turn means that every digit has 10 chances, 0-9.
