Bitcoin Mining Code for Dummies
Let us say you had one legit $20 and one quite good photocopy of the same $20. If someone were to attempt to spend both the true bill and the fake one, someone that took the problem of looking at either of the bills' serial numbers would observe that they had been exactly the exact same number, and thus one of them needed to be fictitious.
This isn't a perfect analogy--we will explain in more detail below. .
Once a miner has verified 1 MB (megabyte) worth 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 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 qualified to earn Bitcoin--not everyone who verifies transactions will get paid off.
1MB of transactions can technically be little as 1 transaction (though 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 work, one is a matter of luck.
2) You must 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 good news: No advanced math or computation is involved. You may have discovered that miners are solving difficult mathematical problems--that is not true in any way. What they are actually 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's guesswork, you need a good deal of computing power in order to get there . To mine , you need to have a higher"hash rate," which 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 with your mining rig's hash rate, the site Cryptocompare offers 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 see this website thousands. Some miners--especially Ethereum miners--purchase individual graphics cards (GPUs) as a cheap method to cobble together mining operations. The photo below is a makeshift, high-tech mining machine. The cards are those rectangular blocks with whirring circles. Note the sandwich twist-ties holding the pictures cards into the metal pole.
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 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 figure any number that is less than or equal to this number I am thinking of.

Let us say I am thinking of the number 19. If Friend A guesses 21they lose because 21>19. If Friend B supposes 16 and Friend C supposes 12, then other they've 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 target 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 that are equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --that miner to honour. Normally, it is the miner that has done the most work, i.e.

The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of this alphabet. Why is that
In order to understand these letters are doing in the middle of numbers, let's unpack the term"hexadecimal."
As you knowwe utilize the"decimal" system, which means it's base 10. This in turn means that each and every digit has 10 possibilities, 0-9.
