Abstract generation in progress

Bitcoin mining is not just a competition of computational power; it is a story of technological evolution itself. Over the past 12 years, the hardware used for mining has changed dramatically.

Mining Starting from the CPU Era

In the early stages from 2009 to 2010, Bitcoin mining was performed using personal computer CPUs. At that time, anyone could participate, and the mining difficulty was much lower compared to today. However, this era was short-lived.

Rapid Adoption of GPU Mining

Between 2010 and 2011, the situation changed dramatically. It was discovered that GPUs, specialized for graphics processing, could perform calculations far faster than CPUs. Laszlo Hanyecz is known as a pioneer of GPU mining, and his pioneering efforts marked a turning point in mining efficiency. The GPU era was also the last time individual miners could easily enter the market.

FPGA Mining: A Transitional Period

From 2011 to 2012, even more advanced hardware emerged. This was FPGA mining. FPGA (Field-Programmable Gate Array) is a special chip that can be reprogrammed to change its functions, significantly improving efficiency per watt compared to GPUs. However, FPGA mining required specialized knowledge and was considered intermediate-level technology.

Industrialization with the Introduction of ASICs

The true turning point came in 2012. Dedicated ASIC miners designed specifically for Bitcoin mining were introduced to the market. At this moment, mining became fully industrialized. ASIC chips are optimized solely for Bitcoin calculations, and their mining efficiency per watt far surpassed FPGA and GPU solutions.

Transition to the Pool Era: From Individuals to Consolidation

From 2013 onward, the landscape of mining changed significantly. Due to the need for massive investments in ASIC hardware, individual miners rapidly exited the market, and mining pools and large-scale mining facilities in clusters began to dominate the industry. The sharing of resources and reward distribution mechanisms created an environment where even small-scale entrants could expect stable returns.

Bitcoin mining technology continues to evolve, always following the simple principle of pursuing efficiency.
