The 9-Minute Rule for Help Wikipedia
Let's say you had one legit $20 and one quite good photocopy of that same $20. If someone were to try to spend both the true bill and the fake one, someone that took the problem of looking at either of those bills' consecutive numbers would observe that they were exactly the exact same number, and thus one of them needed to be false.
This isn't a perfect 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 can be a matter of controversy, as some miners think the block size should be increased to accommodate more data.
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 little as 1 transaction (although this is not in any way 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 effort, one is a matter of luck.
2) You must be the first miner to reach the right answer to a 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 discovered that miners are solving challenging mathematical problems--that is not true at all. What they are actually doing is trying to be the first miner to think of a 64-digit hexadecimal number (a"hash") that is less than or equivalent to the hash.

The bad news: Because it is guesswork, you need a good deal of computing power in order to get there . To mine successfully, you need to have a high"hash speed," 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 how much Bitcoin you could mine along with your mining rig's hash pace, the site Cryptocompare offers a 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 method to cobble together mining 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 graphics cards into the metal pole.
ExampleI 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 try here friends don't have to guess the exact number, they simply must be the very first person to guess any number that's less than or equal to the number I'm thinking of.

Let us say I'm thinking of the number 19. If Friend A guesses 21they shed because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they have 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 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 that are equivalent to or less than the target number, the Bitcoin network will determine by a simple majority--51 percent --which miner to honour. Normally, it is the miner who has done the most work, i.e.
The 6-Minute Rule for 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 this alphabet. Why is that
In order to understand these letters are doing in the middle of numbers, let's unpack the word"hexadecimal."
As you know, we utilize the"decimal" system, which means it is base 10. This in turn means that every digit has 10 possibilities, 0-9.
