Indicators on Help Wikipedia You Should Know
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 fake one, someone that took the trouble of looking at either of the bills' consecutive numbers would see that they were the same number, and thus one of them needed to be fictitious.
This isn't a great analogy--we'll 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 established by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size should be increased to accommodate more information.
Note that I stated that verifying 1 MB worth of transactions makes a miner eligible to earn Bitcoin--not everyone who supports transactions will get paid off.
1MB of transactions can technically be little 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 fulfill two conditions. One is a matter of work, one is a matter of luck.
2) You must be the first miner to arrive at the perfect answer to a numeric problem. This practice is also known as an evidence of work.
The good news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that's 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 target 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 higher"hash rate," that 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 along with your mining rig's hash pace, the site Cryptocompare provides a very 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--especially Ethereum miners--purchase individual graphics cards (GPUs) as a cheap way to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The graphics cards are such rectangular cubes with whirring circles. Note the sandwich twist-ties holding the graphics cards to the metal rod.
Example: I tell three friends that you can find out more 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 have to guess the specific number, they just have to be the very first person to guess any number that is less than or equal to this number I'm thinking of.

Let us say I am thinking of 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 theoretically arrived at workable answers, because 16<19 and 12<19. There's no"extra credit" for Friend B, even though B's answer was nearer to the goal answer of 19. .
In Bitcoin terms, simultaneous 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 percent --which miner to honour. Typically, it's the miner that has done the most work, i.e.

The number above has 64 digits. Easy enough to understand so far. As you likely noticed, that number consists not just 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 is base 10. This in turn means that every digit has 10 chances, 0-9.
