Mining bitcoin Ethereum Zec
Bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of 
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
At present, the mining mode can be roughly divided into PPLNs, PPS and PPS +. However, if you want to get a stable income from mining, it is recommended to choose the mining software of PPS mode
when miners are mining, if you want to know how many etheric coins you get, you can use ha Yu miner to see clearly the daily mining income
Harbin miners showed a unified display of revenue for BTC, easy to see, and support for cash withdrawals to Alipay wallet and bitcoin wallet. p>
Bitcoin is mined in units called "blocks.". At the time of writing, the reward for completing a block is 12.5 bitcoin. In February 2019, the price of bitcoin is about $3500 per bitcoin, which means you will get (12.5 x 3500) = $42000 Refer to bitcoin mining)
as the channel is widely covered, negative interest rates will be passed to consumers through savings accounts that generate negative returns, which will force consumers to find alternatives such as bitcoin
(1) jaw crusher (tiger mouth): the crushing action is to periodically press the movable jaw plate to the fixed jaw plate to crush the ore block in it
(2)
cone crusher: the ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block
(3)
roller crusher: in the gap between two opposite rotating round rollers, the ore block is mainly subject to continuous crushing, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting
(4)
impact crusher: the ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher<
(5)
grinding machine: the ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
(6)
other types of crushing mills: A. roller mill: crushing materials by rotating rollers< B. disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part
C. centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing
D. vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect. All kinds of crushers have different specifications, different scope of use. At present, jaw crusher or rotary cone crusher are mostly used for coarse crushing in concentrator; The standard cone crusher is used for intermediate crushing; Short head cone crusher is used for fine crushing.
On September 17, Alibaba cloud released its first cloud computer "shadowless", which broke through the physical limitations of traditional computers. A "small card" has dozens of times the performance of ordinary computers
it is learned that cloud computing technology is actually used to create a remote virtual host that is the same as personal computer. When users access the network, they can get the same experience as using personal computer
Zhang Jianfeng, President of Alibaba cloud intelligence, said that in the future, everyone can have a supercomputer on the cloud, which can expand the computing power anytime and anywhere according to their needs. After large-scale promotion, it can save 50% of the computing resources for the whole society and avoid the waste of computing power
extended data
some local governments have put forward their purchase intention:
"shadowless" cloud computer has many advantages, such as no physical host, users can save space, in addition, cloud computer adopts very secure encryption mechanism, which effectively prevents Trojans and viruses from stealing important information from users, It has the same security protection level as alicloud data center, which is very reliable
Alibaba cloud computer "shadowless" also has intelligent properties, which can combine your work interface according to your work habits, work content and intelligence, so that users can efficiently complete their work tasks as soon as they open "shadowless", greatly improving efficiency
it is reported that at present, Wuyi is only available for sale in the enterprise office market. In the future, it may provide services to indivial users, and some local governments have put forward the purchase intention
