# Some Known Details About How Bitcoins Are Made

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

That isn't a perfect analogy--we will 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 is a matter of controversy, as some miners believe the block size should be increased to accommodate more data.

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

1MB of transactions can theoretically be as small as 1 transaction (although this is not at all common) or several thousand. It depends on how much information 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 are actually 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 hash.

The bad news: Since it's guesswork, you need a good deal of computing power in order to get there . To mine successfully, you need to get a higher"hash speed," which 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 how much Bitcoin you could mine along with your mining rig's hash pace, the site Cryptocompare offers a very helpful calculator.

Either 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--purchase individual graphics cards (GPUs) as a cheap Source method to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards into the metal rod.

Case in point I tell three friends I'm thinking of a number between 1 and 100, and 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 have to be the first person to guess any number that is less than or equal to the number I am thinking of.

Let us say I'm thinking about 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 have both technically came at viable answers, since 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .

In Bitcoin conditions, simultaneous view website answers happen 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. Normally, it is the miner that has done the most work, i.e. check my source

The losing block then becomes an"orphan block" .

Now imagine I pose the"figure what number I am thinking of" question, but I'm not asking only three friends, and I'm 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 ideal answer.

The number above 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 the alphabet. Why is that

In order to understand what 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 is base 10. This in turn means that every digit has 10 chances, 0-9.
