25000 mining troops in Sichuan: a flood cost hundreds of millions, most afraid of power failure and loneliness
these computing power are scattered along the Da River, a tributary of the Minjiang River. They inlge in the night of Dalate Banner in Ordos, and sleep soundly in a small city in Yili Kazakh Autonomous Prefecture of Xinjiang
today, bitcoin's total network computing power has reached about 30 billion hash collisions per second, equivalent to about 600 tianhe-2 supercomputers, and it is still growing at a high speed. " Wu Jihan, the founder of bitcontinent, wrote in the beauty of computing power
he preached a set of infinitely beautiful "computational aesthetics", but behind the aesthetics is the cruel computational world and interests. Mining is moving towards instrialization step by step and becoming a game of capital
at this time, decentralized mining machines and pools began to appear. They called themselves revolutionaries and wanted to change the extremely monopolized bitcoin world
"cloud computing power mining" is one of them
their way of playing is to establish a number of distributed mines and provide computing power leasing services with tens of thousands of real mining machines
"the current computing power is too concentrated, and some decentralized play methods are difficult to change the current pattern and ecology." Li Ke said
but the essence of blockchain is decentralization. The miners still have the belief that eventually the mining instry will be broken by the decentralized mining pool
this may be the only belief that keeps them going
how long will it take
"5-10 years, slowly nibbling at the giant's territory." Li Ke said
but will giants wait for the revolution? Will they fight back
the battle of computing power and the spark of revolution have just been ignited

From April 2010 to February 2013, the 207 geological team of Sichuan Bureau of Geology and mineral resources carried out exploration work, taking type I 800m × 400 meters basic network. That is 400 meters × To explore and prove the (331) resource quantity, the project spacing of 200m densification should be doubled; 800 meters × 400m basic network engineering network exploration control (332) resource layout exploration engineering. Combined with the distribution, occurrence and shape of phosphorus ore bed in the mining area and the mine development planning, drilling and pit exploration engineering is adopted to control the phosphorus deposit. There are 5 exploration tunnels in the whole mining area, namely pd1015, pd1139, pd1032, pd1033 and pd1070. The construction shall be organized according to the principle of detailed investigation before exploration. The exploration work in the mining area lasted 35 months from March 2010 to February 2013. In June 2013, the exploration report of liugushui phosphate rock in Mabian County, Sichuan Province was submitted for approvalhope to help you
most of the rich minerals in hilisus are in wormholes, so it is not recommended to use Ms; The terrain of Dongquan Valley is a little complicated. It is not recommended to climb mountains
so you can go to the crater and walk around the edge of the mountain to dig. There are a lot of places like Isala, Heather and fuser.
