Mining is the process of adding transaction records to Bitcoin s public ledger of past transactions. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction feesBitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous paymentBelow are statistics about the Bitcoin Mining performance of ASIC hardware and only includes specialized equipment that has been shipped.
GPUs, CPUs and other hardware not specifically designed for Bitcoin mining can be found in the Non-specialized_hardware_comparison. Notes: Mhash/s = millions hashes per second (double sha256 raw speed performance; may not be very energy efficient with some models) Mhash/J = millions hashes per joule (energy efficiency; 1 joule of energy is 1 watt during 1 second: 1 J = 1 W*s) W = watt (maximum power consumption, i.e. energy per unit of time: 1 W = 1 J/s) Be sure to research any of these vendors and machines intensely before spending any money.

With paper money, a government decides when to print and distribute money. Bitcoin doesn t have a central government. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

So how does someone get into the current bitcoin rush? If properly done and willing to take the investment risk, you could wind up with a few bitcoins of your own—which currently have an average weekly price of $945 on the largest bitcoin exchange. Here s how it s done. When the algorithm was created under the pseudonym Satoshi Nakamoto—which in Japanese is as common a name as Steve Smith—the individual(s) set a finite limit on the number of bitcoins that will ever exist: 21 million. Currently, more than 12 million are in circulation. That means that a little less than 9 million bitcoins are waiting to be discovered.
Since 2009, the number of bitcoins mined has skyrocketed. That s the way the system was set up—easy to mine in the beginning, and harder as we approach that 21 millionth bitcoin.
At the current rate of creation, the final bitcoin will be mined in the year 2140.

In this post, we attempt to identify some top 10 questions about Bitcoins to give you a clearer understanding of what it is, what it does and how you can use it to buy products or services online. 2. Who Developed The Idea Of Bitcoins? The concept of Bitcoins was developed by Satoshi Nakamoto, who resides in total anonymity. He is said to be from Japan but his mail ID was from Germany, plus the bitcoin software was not available in Japanese. He developed the system and the Bitcoin software (that is used to run the system) in 2009 but disappeared into thin air in 2010. The other developers of the system stopped hearing from him in 2010, and plenty of speculation turned up about his real identity.
Some even suggested that his name was just a mashup of popular Japanese companies — SAmsung TOSHIba NAKAmichi MOTOrola. But what heOne of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. I am not a professional coder, I have no experience with Ubuntu, Linux and minimal experience with Mac.
So, this is for the individual or group that wants to get started the easy way. First thing you need to do is get a “Bitcoin Wallet”. Because Bitcoin is an internet based currency, you need a place to keep your Bitcoins.
Got to and download the Bitcoin client for your Operating System. Install it the client will begin to download the blockchain. Downloading the blockchain can take a long time and will be over 6GB of data. If you have data caps, I would recommend ordering a copy of the blockchain on DVD to keep from going over as it is growing exponentially. Click to order the bitcoin blockchain by mail. Once the client is up to date, click “New” to get your wallet address. It will be a long.
