Bitcoin mining has undergone significant transformations since its inception. Initially, from 2009 to 2010, mining was conducted using CPUs, which were soon outpaced by the more efficient GPU mining era from 2010 to 2011. Laszlo Hanyecz, known for the first real-world Bitcoin transaction, was a pioneer in GPU mining, which allowed for significantly faster processing than CPUs. The period from 2011 to 2012 saw the introduction of FPGA mining, offering further efficiency improvements. The real breakthrough came in 2012 with the advent of ASIC miners, specifically designed for Bitcoin mining, marking a new era of increased mining power and efficiency. Since 2013, mining has largely been dominated by mining pools and clusters, allowing for collective resource sharing and increased chances of mining success.
