# Help Wikipedia Can Be Fun For Anyone

Let's say you had one legit $20 and one really good photocopy of that same $20. If someone were to attempt to spend both the true bill and the imitation one, someone who took the problem of looking at either of those bills' serial numbers would see that they had been the same number, and thus one of them had to be false.

This isn't a great analogy--we will explain in more detail below. .

Once a miner has verified 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 think 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 get paid off.

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 arrive at the right answer to some numeric issue. This process is also known as an evidence of work.

The fantastic news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems--that's not true in any way. What they are doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") which is less than or equal to the hash.

The bad news: Since it's guesswork, you need a lot of computing power in order to get there first. To mine successfully, you need to get a high"hash rate," that is measured website here 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 rate, the website Cryptocompare provides 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 low-cost way to cobble together mining operations. The photograph below is a makeshift, high-tech mining machine. The cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal rod.

Example: I tell three friends that I'm thinking about a number between 1 and 100, and I write that number on a sheet of paper and seal look at more info it in an envelope. My friends don't have to guess the specific number, they just must be the very first person to guess any number that is less than or equal to this number I'm thinking of.

Let's 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 guesses 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 nearer to the target answer of 19. .

In Bitcoin terms, simultaneous answers occur 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 determine by a simple majority--51%--that miner to honour. Typically, it is 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 am thinking of" question, however I am not asking just three friends, and I'm not thinking of a number between 1 and 100. Instead, I'm asking millions of would-be miners and I am thinking about a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right answer.

## The 7-Minute Rule for Bitcoin Trading History

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 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.
