Currently this bounty is See Controlled Currency Supply. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block.

In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income. Users have used various types of hardware over time to mine blocks.
Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page. Early Bitcoin client versions allowed users to use their CPUs to mine. The option was therefore removed from the core Bitcoin client's user interface.
See the main article: A variety of popular mining rigs have been documented. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining. An application-specific integrated circuit, or ASIC , is a microchip designed and manufactured for a very specific purpose.
How mining works
ASICs designed for Bitcoin mining were first released in For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially. Mining contractors provide mining services with performance specified by contract, often referred to as a "Mining Contract. As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts.
This made mining something of a gamble.

To address the variance in their income miners started organizing themselves into pools so that they could share rewards more evenly. See Pooled mining and Comparison of mining pools. Bitcoin's public ledger the "block chain" was started on January 3rd, at The first block is known as the genesis block. The first transaction recorded in the first block was a single transaction paying the reward of 50 new bitcoins to its creator.

The ledger is needed for the nodes of the Bitcoin network to always be able to confirm valid transactions. In order to become a Bitcoin miner, a person first needs a computer and mining software - like the GUIMiner. Every , blocks, or, roughly, every four years, the block reward is halved.
Bitcoin is Secure
It started at 50 Bitcoin per block in , and in it was halved to 25 Bitcoins per block. However, mining on personal computers has only been feasible in the early years of Bitcoin. By now, the network is so competitive, that using specialized hardware is the only way to make a profit. The first ASICs - or Application-Specific Integrated Circuits - were introduced in , designed specifically for the purpose of mining from the start. And the problem of paying for electricity bills is only exacerbated by the new, power-hungry hardware.
How Are New Bitcoins Created? A Brief Guide to Bitcoin Mining
Nowadays there are many prominent companies which design and produce mining hardware. Among them, are Bitfury , Bitmain. You may also find used equipment on eBay or Amazon. Bitcoin uses a cryptographic hash function SHA for encryption. This algorithm allows you to take data of any size and turn it into a string of a specific, predefined size. The difficulty is automatically adjusted every blocks - or, roughly, every 14 days - in accordance with the growing or shrinking combined computational power of the network.
If the network became more powerful over the last blocks, then the difficulty value is decreased to make it harder to find a valid hash and vice versa.
How Are New Bitcoins Created? A Brief Guide to Bitcoin Mining
Considering the immense computational power that the Bitcoin network currently employs, it takes trillions of computer-generated guesses from all over the world until the right hash value is found by someone. And if you are the first to do it - congrats! You have just mined a block and got a reward of 12,5 Bitcoins.
