What is commonly referred to as Bitcoin “mining” is really the creation of a new block in the block chain. Instead of making block creation a relatively simple operation, Satoshi realized that only a computationally expensive operation, performed as a kind of lottery, would prevent forgers from subverting the digital currency. But for a computationally expensive operation, which costs CPU power and thus electricity, some kind of reward would be necessary. Otherwise, only people with nefarious intent would participate in block creation. One of the most difficult problems in computer science is reversing a secure hash (finding an input text for a given output, the digital signature). Let me explain this problem in simple terms. Let’s assume the wealthy but terminally ill Alice wrote her will and stored it on her computer. Knowing that a computer can be hacked and the will can be altered, Alice digitally signed her will with the secure hash algorithm SHA-256.
She then emailed the digitalSome Bitcoin users might wonder why there is a huge disparity between the mining output of a CPU versus a GPU. First, just to clarify, the CPU, or central processing unit, is the part of the computer that performs the will of the software loaded on the computer. It s the main executive for the entire machine. It is the master that tells all the parts of the computer what to do - in accordance with the program code of the software, and, hopefully, the will of the user. Most computers have multi-core CPUs nowadays (which is almost the same thing as having multiple CPU s in a single physical package)., and some computers even have multiple CPUs. The CPU is usually a removable component that plugs into the computer s main circuit board, or motherboard and sits underneath a large, metallic heat sink which usually has a fan, a few are cooled by water. The GPU, or graphics processing unit, is a part of the video rendering system of a computer. The typical function of a GPU is to assist withWhile the actual process of Bitcoin mining is handled by the Bitcoin mining hardware itself, special Bitcoin mining software is needed to connect your Bitcoin miners to the blockchain and your Bitcoin mining pool as well, if you are part of a Bitcoin mining pool. The software delivers the work to the miners and receives the completed work from the miners and relays that information back to the blockchain and your mining pool. The best Bitcoin mining software can run on almost any operating system, such as OSX, Windows, Linux, and has even been ported to work on a Raspberry Pi with some modifications for drivers depending on your mining setup. Not only does the Bitcoin mining software relay the input and output of your Bitcoin miners to the blockchain, but it also monitors them and displays general statistics such as the temperature, hashrate, fan speed, and average speed of the Bitcoin miner. There are a few different types of Bitcoin mining software out there and each have their ownFirst Bitcoin mining pool in the world Operating since December 2010 Over 939,000 BTC mined since December 2010 Long history of stable and accurateGUIMiner is a graphical frontend for mining Bitcoins, providing a convenient way to operate Bitcoin miners from a graphical interface. It supports both AMD and NVIDIA GPUs, as well as CPU mining. You can choose between pooled mining and solo mining - the software embeds a list of mining pools to choose from. Where can I download GUIMiner? You can download GUIMiner from the official GitHub repo . Can I use GUIMiner to mine Litecoin? In order to mine Litecoin, you have to use GUIMiner-scrypt . Where can I get news and updates about GUIMiner? Have a look at the official forum thread onI am trying to setup GUIMiner together with mining.bitcoin.cz.
As I am working on a laptop with an Intel graphic card I am (probably?) unable to use GPU mining.

General What is Bitcoin? Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer . What is GUIMiner? GUIMiner is a graphical frontend for mining Bitcoins, providing a convenient way to operate Bitcoin miners from a graphicalAt first, miners used their central processing unit (CPU) to mine, but soon this wasn t fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work. During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection. FPGA miners used much less power than CPU s or GPU s and made concentrated mining farms possible for the first time. Today s modern and best bitcoin mining hardware Application-specific integrated circuit (ASIC) miners have taken over completely. These ASIC machines mine at unprecedented speedscpuminer is a simple client program that performs Pooled Mining or solo mining. The program receives proposed block data from the server, for which it tries to guess a nonce value that will result in a valid block. If a block hash with at least 32 consecutive zero bits is found, the block data containing the guessed nonce value is sent back to the server. If used in Pooled Mining mode, this block is called a share because the server is supposed to credit the registered user s account, according to the number of shares that user has contributed, and eventually transfer an amount of bitcoins to the registered user s address. Communication with the server is done using HTTP POST requests on port 8332 by default, containing JSON-encoded data. For pooled mining, users are required to register on such servers (so as to give their Bitcoin address) and HTTP username:password authentication is required. For solo mining, the username/password is set in bitcoin.conf. The calculations are.
