However, just how can you create a system Which Has a decentralized ledger How can you give someone the ability to update the ledger without giving them a lot of powerin case they become corrupt or negligent in their job
Well, Bitcoins rulesalso known as the Bitcoin protocolsolves this in a Really creative way I like to phone Who Wants to Be a Banker
In short, anyone who wants to participate in updating the ledger of all Bitcoin transactions, known as the blockchain, can do so. All you need is to suppose a random number that solves an equation generated by the computer system. Sounds easy, right

Of course, this guessing is all done by your PC. The stronger your computer is, the more supposes you can make in one second, increasing your chances of winning this match. If you manage to figure correctly, you earn bitcoins and get to write the next page of Bitcoin transactions on the blockchain. .

1. Once your mining computer comes up with the ideal suspect, your mining program determines which of these current pending transactions will be grouped together into the next block of transactions. Compiling this cube represents your moment of glory, as youve now develop into a temporary banker of Bitcoin who has to upgrade the Bitcoin transaction ledger known as the blockchain. .
2. The block youve generated, along with your solution, is sent to the entire network so other computers can validate it. Its somewhat much like a Rubiks cube: The solution is quite hard to attain but very easy to validate.
3. Each computer that validates your solution updates its copy of this Bitcoin transaction ledger together with the transactions you opted to include in the block.
4. The machine generates a predetermined amount of bitcoins (currently 12.5) and rewards them as compensation for time and energy you spent solving the math issue.

So thats Bitcoin mining in a nutshell. Its called mining because of the fact that this process helps mine new Bitcoins from the system. But if you think about it, the mining component is merely a by-product of this transaction confirmation procedure. Therefore that the name is a bit misleading, since the main objective of mining is to maintain the ledger in a decentralized manner. .
As you can imagine, since mining is based on a form of guessing, for every block, a different miner will guess the number and also be granted the right to upgrade the blockchain. Obviously, that the miners with computing power will succeed more often, but due to the law of statistical probability, its highly unlikely that the same miner will succeed each time. .
Now you know what Bitcoin mining is, you may be thinking, Cool! Free money! Where do I sign up Well, not so fast
Satoshi Nakamoto, who invented Bitcoin, crafted the principles for mining in a way that the further mining power the network gets, the harder it is to imagine the answer to the mining math problem. So that the difficulty of the mining process is really self-adjusting to the gathered mining power the network owns. .
If more miners join, it will get harder to address the issue; if many of them fall off, it will get easier. This is known as mining issue.
Now, remember, this is on average. We can have two cubes being added minute after minute and then wait an hour to the next block. In the long run, this will even out to ten minutes on average.
As you can imagine, this kind of self-adjusting mechanism has created a type of arms race to get the most efficient and strong miners as soon as possible.

When Bitcoin first started out, there werent a great deal of miners on the market. In fact, Satoshi, the inventor of Bitcoin, and also his friend Hal Finney were a few the only people mining Bitcoin back at the time with their own personal computers.
Using your CPU (central processing unityour computers brain and an integrated component in any computer) was enough for mining Bitcoin back in 2009, since mining issue was low. As Bitcoin started to catch on, people looked for more powerful mining solutions.
