# The 9-Minute Rule for Help Wikipedia

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 real bill and the imitation one, someone who took the problem of looking at both of those bills' consecutive numbers would see that they had been exactly the same number, and thus one of them needed to be fictitious.

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

Once a miner has verified 1 MB (megabyte) worth of Bitcoin transactions, they are eligible to win the 12.5 BTC. The 1 MB limit was set by Satoshi Nakamoto, and can be a matter of controversy, as some miners believe the block size ought to be increased to accommodate more information.

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

1MB of transactions can theoretically be as little as 1 transaction (though this is not in any way common) or a few thousand. It depends on how much data the transactions take up.

In order to earn Bitcoin, you need to fulfill 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 a numeric problem. This practice 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 is not true at all. What they're 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.

# Getting The Money To Bitcoin To Work

The bad news: Since it is guesswork, you need a good deal of computing power in order to get there . To mine , you need to have a high"hash rate," 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 along with your mining rig's hash rate, the site Cryptocompare provides a helpful calculator.

Either way a GPU (graphics processing see here 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 way to cobble together mining view it operations. The photo below is a makeshift, home-made mining machine. The cards are such rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards to the metal pole.

Case in point : I tell three friends that 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 need to guess the specific number, they just have to be the first person to guess any number that's less than or equal to the number I'm thinking of.

## 20000 Satoshi Things To Know Before You Get This

Let us say I am thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they've both technically came at viable answers, because 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 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 which can be equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--that miner to honour. Typically, it is the miner that has done the most work, i.e.

## About 20000 Satoshi

The number preceding has 64 digits. Easy enough to understand so far. As you probably 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 term"hexadecimal."

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