The story of ASIC started of course in 2009 when Bitcoin mining first started. In that time, you only needed a home computer as a hardware product to mine Bitcoin. They ran standard multicore CPUs (Central Processing Unit) and would mine BTC at a rate of 50 per block.
The demand for bitcoin miners increased drastically the more Bitcoin became popular over the years. The climax was reached in October 2010. This year, the code for mining Bitcoin with GPUs (Graphic Processing Unit) was introduced to the public. The problem here was, that it was still very hard for GPU users to scale hash rates. So the more powerful and efficient FPGAs (Field-programmable gate array) were released and mining really began to grow.
The adoption of ASIC (Application-specific Integrated Circuit) technology was developed very far by 2012. These miners were specifically made to mine cryptocurrencies and replacing big parts of FPGAs. Because the demand was so high, ASICs continued their progress and products kept improving, and they are indispensable for the Bitcoin mining industry.
Since 2013 Bitmain is the leader in the mining industry which is continuously growing.
That year Bitmain brought ASICs, which are designed to mine specific cryptocurrency to the public. In November 2013 the Antminer S1 is born. Bitmain released its own ASIC. It had a hash rate of 180 GH/s. Followed by the Antminer S2 with an increased hash rate of 1 TH/s. This growth and progress in power and energy-efficiency continued with the years. So the latest generation of ASIC miners is the Antminer S19 Series.
