The company was founded in 2011 by Valery Vavilov. Initially, the company started to experiment and mine bitcoins, using CPUs and PC GPUs. It then began to design ASIC chip. According to Vavilov, in 2013 the company managed to develop a chip for 55-nanometer technology and adjust its production under its own brand. Start-up capital amounted to 110 thousand dollars of own funds, resources for subsequent growth provided a rapid increase in the cost of bitcoin, including a jump in the rate from 100 to 1200 dollars in November 2013.

In 2014, the company started mining using its own equipment in Finland, Iceland and Georgia- becoming one of the first “industrial” miners. The computing power of the company has long been in the Ghash At the beginning of June 2014, the capacity of the pool, in which the share of Bitfury ASIC chips was about 45%, for some time exceeded 51% of the total computing power of the entire bitcoin network, which made “double spending” possible. To reduce the risk of centralizing the network, the company removed some of its servers from As of 2017, Bitfury controls about 9.5 % of the computing power of the Bitcoin network.

In 2014-2015, the company attracted 3 rounds of investments of $ 20 million, which was half of all global investments in bitcoin infrastructure in the middle of 2015.

In October 2013, it was announced that the new chip is based on 28-nm technology, consumes of 0.2 Joule at gigaherz. Mass production of the new chip began in late February 2015.

16-nm ASIC chip

The chip, using 16-nm (nanometer) technology, was announced in December 2015. Since October 2016, it has been implemented in the data centers of the company. In accordance with the company specifications, the new chip consumes about 0.06 joules per gigaherz (four times less than on the market ICS) and provides performance of up to 140 gigaherz per second with air cooling and up to 184 with the immersion.
