# The 5-Second Trick For 20000 Satoshi

Let us say you had one legit $20 and one quite good photocopy of the same $20. If someone were to try 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 exact same number, and thus one of them had to be fictitious.

This isn't a perfect analogy--we'll explain in more detail below. .

Once a miner has verified 1 MB (megabyte) worthiness of Bitcoin transactions, they are entitled 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 think the block size should be increased to accommodate more information.

Note that I said that verifying 1 MB value of transactions makes a miner eligible to earn Bitcoin--not everyone who verifies transactions will receive 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 data the transactions consume.

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 have to be the first miner to arrive at the perfect 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 heard that miners are solving difficult mathematical problems--that is not true in any way. What they're 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: Because it is guesswork, you need a lot of computing power in order to get there . To mine , 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 just how much Bitcoin you can mine along with your mining rig's hash pace, 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 to the tens of thousands. Some miners--especially Ethereum miners--buy individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photo below is a like it makeshift, home-made mining machine. The graphics cards are those rectangular cubes with whirring circles. Note the sandwich twist-ties great site holding the graphics cards to the metal rod.

Case in point : I tell three friends that I'm thinking about 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 must be the first person to figure any number that's less than or equal to the number I'm thinking of.

## The Best Strategy To Use For How Bitcoins Are Made

Let's say I am thinking about the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C supposes 12, then they've both theoretically arrived at workable answers, since 16<19 and 12<19. There is no"extra credit" for Friend B, even though B's answer was closer to the target answer of 19. .

In Bitcoin conditions, 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 from this source the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Normally, it's the miner that has done the work, i.e.

The losing block then becomes an"orphan block" .

Now imagine that I pose the"figure what number I'm thinking of" question, but I am not asking just 3 friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be 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 right answer.

## The 20-Second Trick For How Bitcoins Are Made

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

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

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