((("mining and consensus", "hashing power race", id="MAChash10")))Bitcoin mining is an extremely competitive industry. The hashing power has increased exponentially every year of bitcoin's existence. Some years the growth has reflected a complete change of technology, such as in 2010 and 2011 when many miners switched from using CPU mining to GPU mining and field programmable gate array (FPGA) mining. In 2013 the introduction of ASIC mining lead to another giant leap in mining power, by placing the SHA256 function directly on silicon chips specialized for the purpose of mining. The first such chips could deliver more mining power in a single box than the entire bitcoin network in 2010.
The following list shows the total hashing power of the bitcoin network, over the first five years of operation:
The following list shows the total hashing power of the bitcoin network, over the first eight years of operation:
2009:: 0.5 MH/sec–8 MH/sec (16× growth)
2010:: 8 MH/sec–116 GH/sec (14,500× growth)
