Approximate Bitcoin Mining process devised by University of Illinois researchers is slated to improve the mining process by about 30 percent
People always want to get the most out of their bitcoin mining rigs and rightly so. The difficulty levels of bitcoin algorithm are increasing daily and mining has become a competitive affair. Those who discover fresh blocks stand to gain the bitcoin network reward. In order to discover new blocks, the mining chips have to be able to generate enough processing power to break the encryption protocol to find the cryptographic nonce value for the new block. This processing power is supplied by custom built bitcoin mining application specific integrated circuits (ASICs).
