# Bitcoin Mining Code for Dummies

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

That isn't a great analogy--we'll explain in more detail below. .

Once a miner has confirmed 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 can be an issue of controversy, as some miners think the block size should be increased to accommodate more information.

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

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

2) You have to be the first miner to reach the right answer to some numeric problem. This practice is also known as a proof of work.

The fantastic news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that is 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 hash.

The bad news: Since it is guesswork, you need a good deal of computing power in order to get there first. To mine , you need to have a high"hash speed," which 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 just how much Bitcoin you can mine with your mining rig's hash rate, the site 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--particularly 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 cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into 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 have to guess the specific number, they just must be the first person to guess any number that is less than or equal to this number I'm thinking of.

Let us say I'm thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C guesses 12, then they have both technically Resources 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 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 that are equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51%--which miner to honour. Typically, 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"figure what number I'm thinking of" question, visit this site but I am not asking only three friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of prospective miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it is going to be extremely difficult to guess the ideal answer.

## A Biased View of 20000 Satoshi

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

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

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