 The following list shows the total hashing power of the bitcoin network, over the first five years of operation:
 
-* 2009—0.5 MH/sec to 8 MH/sec (&#x00D7; 16 growth)
-* 2010—8 MH/sec to 116 GH/sec (&#x00D7; 14,500 growth)
-* 2011—16 GH/sec - 9 TH/sec (&#x00D7; 562 growth)
-* 2012—9 TH/sec - 23 TH/sec (&#x00D7; 2.5 growth)
-* 2013—23 TH/sec - 10 PH/sec (&#x00D7; 450 growth)

 In the chart in <<network_hashing_power>>, we see the bitcoin network's hashing power increase over the past two years. As you can see, the competition between miners and the growth of bitcoin has resulted in an exponential increase in the hashing power (total hashes per second across the network).
