bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
has two main advantages compared with windows
(1) stable system: for example, it is very common for a host with Linux to run continuously for more than one year without downtime or shutdown. My windows system turned on black screen this morning, and then recovered after forced shutdown
(2) fast repair of security and vulnerability: Linux is used by many computer experts, so there are many maintainers, and the update and maintenance is fast, while windows is used by everyone, and it is not open source
therefore, the core system of mining machine is Linux. At present, more than 95% of the global server market choose Linux, which has been verified for a long time, and windows is not recommended as the operating system< The second key point of mining machine is: hard disk
(1) the number of hard disk bits
IPFs is storage mining, and the mining benefit is directly proportional to the size of storage capacity, so if you want to dig more money, you have to have more hard disk bits, and the mining machine with 16 disks and 24 disks is preferred
(2) hard disk installation
if you need to shut down every time you increase or decrease the hard disk, you may not get enough money to be punished and dected. IPFs mining machine needs to work stably, so it must support hot plug
(3) hard disk compatibility
supports the mixed insertion of different brands and capacities of hard disks, which can be collocated at will according to their own needs. Only by making full use of the capacity of hard disks can we maximize the revenue
the third key point of mining machine: CPU, motherboard
CPU and motherboard should be able to point out the actual working situation of multiple hard disks, and the hardware collocation should be reasonable. For example, the configuration can only support 4T multiple hard disks. If multiple 8t hard disks are inserted, it will lead to a small horse pulling a cart, causing a crash and burning the hard disk, motherboard, CPU, etc. Therefore, the hardware configuration should be rendant, and about 8t hard disk storage space should be reserved< Key points of Miner: built in mining software
the performance of built-in mining software is better, otherwise the miner's mining situation can't be well connected with the main chain, and the main chain can't read the miner's work well, resulting in data loss and mapping data error. For example, if you save 20t and the main chain only reads 10t, you will lose the reward of storing 10t. So the software R & D team must have strength. With the upgrading of technology and the analysis of mining data, software system is also needed to ensure or improve the mining efficiency.

In the era when the two child policy is fully open, many young consumers of the new generation are also facing the challenge of & quot; There are old people on the top and small people on the bottom; It is difficult for families with large population to travel. For them, at the same price, an MPV that can be installed more than a car and is more practical than an SUV is a better choice for a 100000 class family car. Moreover, in recent years, major automobile brands have made great progress in the rejuvenation of models, and many popular fashion models have emerged in the MPV market, such as xinbaojun rm-5, Geely Jiaji and GAC motor Gm6, which are benchmark players in domestic MPV. So, how should consumers choose these three MPVS which are both practical and beautiful
It can be said that in terms of the three cars introced today, high appearance, large space, strong practicability and high comfort are their highlights. After all, as a 100000 class MPV with both practicality and beauty, it can easily meet the basic needs of a family's travel. No matter which one you choose, I believe it will not make you regretthis article comes from the author of car home, which does not represent the standpoint of car home
#include <stdio.h>

Of course, with the development of the times and the progress of technology, this set of car engine system will continue to evolve in the future, becoming more intelligent and more humanized, which is a great blessing for both old and new car owners. It is believed that Geely will continue to forge ahead in the field of intelligent vehicle networking, and the gkui system will continue to evolve. In the future, ECAT will release more smart car upgrade plans for Geely's old models, and users can choose according to their own usage habits and scenarios. Become a better proct, let more users enjoy the intelligent experience brought by the development of science and technology. The appearance of the 2020 boyue is still beautiful. It has a family style design. The grid in the ripples of water drops and the black and blue vehicle logo are very harmonious. It looks very classic, rable and atmospheric. There are sharp led eagle eye headlights on both sides. The side of the boyue has a waist line inclined upward, which makes it feel very powerful. The suspended roof design can be said to be advanced design. After the blackened tail lamp is lit at night, the recognition degree is quite high.? Geely boyue's interior is amazing, with a good sense of coordination, a Chinese style visual experience, a flat bottomed D-type steering wheel, a sense of movement, a full LCD dashboard and an intelligent Internet vehicle, which makes boyue's interior full of a sense of science and technology. The materials used in boyue's interior are also conscientious. Soft materials are used in most places, which makes it feel great. The overall feeling of using the car for more than one year is refreshing. None of the car's configuration is idle. It always gives me a lot of surprises. The fuel consumption is about 8.7l/100km. The quality of life of buying this car has improved a lot. I don't worry about breaking down on the road and ending the holiday ahead of time
