Unlike ordinary fiat currencies (such as US dollars or euros) bitcoin resources are not controlled by a central government or bank, and new bitcoin (BTC) cannot be printed and issued like paper money. Instead, bitcoin tokens are introduced into the market by means of a procedure known as mining. BTC are awarded to the miners who've solved the mathematics problems necessary to verify bitcoin transactions. .

All about Where Can You Spend Bitcoin
Whenever a transaction is created in bitcoin, a record of it is made on a block containing other recent transactions, such as, for instance, a webpage in a ledger. Once the block is complete, bitcoin miners compete against one another to confirm and validate the block and its transactions by solving a intricate cryptographic issue. .
The first miner to achieve this is awarded a fixed amount of bitcoin, based on the mining difficulty at the moment. The verified block is then inserted into the blockchain, a record of all blocks verified since the beginning of bitcoin, and transmitted to all users of bitcoin so that they can possess the latest blockchain. .
In the heart of bitcoin mining lies a hard, mathematical problem. The target is to ensure that the process of adding a new block to the blockchain requires a lot of work. That will help to ensure that any hacker tampering with the transactions needs not only to mess with all the transactions but also win the race of bitcoin mining. .
SHA-256 the mining algorithm utilized by bitcoin is a one-way cryptographic algorithm. When you pass a word through SHA-256 you will be given back an unrecognizable string of letters and numbers known as a HASH.
For example, the SHA-256 of this term BUTTERFLY (origin ) is 8c62ace4f9ef8ccd08ca6fb992a8524bb7dbdc0530654bd254c9da07a660949a (HASH). This seemingly random string of letters and numbers has three important properties:
Bitcoin mining involves three factors: the block, the mining difficulty and a random number. Heres how it all comes together:
Imagine our block consists of the term BUTTERFLY discussed earlier. In fact, the block would contain a list of recent, unverified transactions, but lets keep it simple. In order for the block to be solved, bitcoin utilizes a simple test: If the HASH consequence of the block starts with a certain number of zeros, then the block is considered verified.
For our example, lets say that we have a mining difficulty of simply two, ie, our HASH should start with two zeros. .
The problem: BUTTERFLY will return the exact same HASH, and it doesnt begin with two zeros. So what we need is your third factor, a random number (known as a NONCE). We take this number, combine it with BUTTERFLY, and HASH again. If it doesnt start with two zeros, we change the number and try again, and since changing one small number changes the whole HASH outcome, there is no way to predict the number well need to solve this! .
We repeat this process over and over until we find a number that, when combined with BUTTERFLY, gives us a HASH that starts with two zeros. That number is the solution to the block. Here are some attempts:

This arduous procedure of randomly trying to find a number that gives the solution is what creates bitcoin mining such a computationally expensive process and as more miners join the network additional info the harder it gets. At November 2017, a regular home computer working alone, ie, not an application-specific integrated circuit (ASIC) and not part of a cloud mining network, could require 2.7 millionyears to mine one block. .
