Bitcoin mining is the processing of transactions in the digital currency system, in which the records of current Bitcoin transactions, known as a blocks, are added to the record of past transactions, known as the block chain. A Bitcoin is defined by the digitally signed record of its transactions, starting with its creation. The block is an encrypted hash proof of work, created in a compute-intensive process. Miners use software that accesses their processing capacity to solve transaction-related algorithms. In return, they are awarded a certain number of Bitcoins per block. The block chain prevents attempts to spend a Bitcoin more than once — otherwise the digital currency could be counterfeited by copy and paste. Originally, Bitcoin mining was conducted on the CPU s of individual computers, with more cores and greater speed resulting in more profitability.
