More About Bitcoin Mining Code

Let's say you had one legit $20 and one really good photocopy of that same $20. If someone were to try to spend both the true bill and the fake one, someone who took the problem of looking at both of those invoices' serial numbers would observe that they were exactly the same number, and thus one of them needed to be false.

That isn't a great analogy--we'll 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 set by Satoshi Nakamoto, and is an issue of controversy, as some miners believe the block size ought to be increased to accommodate more data.

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

1MB of transactions can theoretically be as small as 1 transaction (though this is not at all common) or a few thousand. It depends on how much information 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 reach the perfect answer to some numeric issue. This process is also known as an evidence of work.

The good 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 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.

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 higher"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 just how much Bitcoin you can mine with your mining rig's hash rate, the site Cryptocompare offers 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--particularly Ethereum miners--buy individual graphics cards (GPUs) as a low-cost way to cobble together mining operations.  The photograph below is a makeshift, home-made mining machine.  The graphics cards are those rectangular cubes with whirring circles.  Note the sandwich twist-ties holding the pictures cards into the metal pole.

Example: I tell three friends that I'm thinking of a number between 1 and 100, and 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 guess any number that's less than or equal to this number I am thinking of.

A Biased View of How Bitcoins Are Made

Let's 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've 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 target 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 that are equal to or less than the target number, the Bitcoin network will decide by a simple majority--51 percent --which miner to honour. Typically, it's the miner that has done the most work, i.e.

The losing block then becomes an"orphan block." .

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

The number preceding has 64 digits. Easy enough to understand so see this website far. 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 center of numbers, let's unpack the word"hexadecimal."

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