Miner DIY

1. I don't have so many machines. I only have more than 20. I've tried kuangbao for some time. When I use kuangbao, the computing power is relatively stable. This thing is a safe one.

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

3. It's mainly mining, but mining also has its own mining and hosting, and hosting is the most efficient

4. Bitcoin is a string of digital codes, which I think the landlord should know. So bitcoin is different from what we usually think of as physical currency. For example, every year, the country issues a certain Zodiac commemorative coin
bitcoin exists in the Internet, because it is essentially an encryption code, so in order to obtain bitcoin, we have to obtain it from the network in a certain way. Just like gold, it needs all kinds of machinery and equipment to dig. Bitcoin mining is also similar to gold mining. It also needs various machines and tools to obtain bitcoin. At the beginning, bitcoin could be g through the computer CPU, but as the value of bitcoin is graally disclosed and enlarged, many people graally improve the performance of mining equipment in order to obtain considerable benefits, that is, to the present ASIC mining machine. Now a miner is equivalent to dozens of computers. The mining ability of this miner is greatly improved, and the probability of obtaining bitcoin is also increased accordingly. However, the power consumption of the mining machine is too high. Most people leave it at home, and the income may not be able to offset the electricity charge. So mining machine mining, has graally become a small part of the financial strength of the game. This is not a good thing for bitcoin
therefore, based on this phenomenon, Xbit mining was born. Xbit mining is mainly based on the calculation power of the entity miner. The difference is that Xbit is equal to 1t calculation power and the power consumption is 60W. It is equivalent to lowering the threshold of participation in mining. Ordinary people also want to participate in bitcoin mining. There are certain ways
in general, if the financial strength and resource strength are strong, you can buy a large number of mining machines to dig bitcoin; Those with limited capital and resources can buy part of Xbit for mining, and finally get bitcoin. Specific choice of which way, mainly according to the owner's own situation.

5. IPFs is a protocol. Star miner. It is said that these are all projects of Nanyue international.

6. Flow every day? I'll see you in a few days

7. Try Tencent computer housekeeper, more comprehensive, more intelligent and more intimate in function
the main functions include security protection, system optimization and software management, which are suitable for Internet users to use every day
real time protection to protect computer security, such as system firewall: computer manager system firewall selects the key locations vulnerable to virus Trojan horse attacks, covering the registry, system services, system files, processes and other protection locations, to protect your system security in an all-round way
Internet Security Firewall: the housekeeper web firewall can monitor the network in real time and effectively intercept the attacks of the Pegasus website on the system. All round guarantee your Internet security
entrance firewall: real time monitoring of USB flash disk can effectively prevent virus Trojan horse from invading the system through USB flash disk.

8. It seems that it hasn't for the time being. The algorithm is different. To do LTC mining machine is to redevelop a CPU. It seems that no one has done it yet. If it's so easy to get mining machine out, LTC mining is very difficult.

9. There are two most direct ways to become a miner. First, DIY assemble mining machine, of course, DIY must have theoretical basis and practical ability. Second, choose a reliable miner supplier, buy their miner, teach them how to excavate, and pay attention to the interstellar bit miner.

10. Interface, number of particles and storage size (including memory interfaces, such as sdram133, ddr333, ddr2-533, ddr2-800, ddr3-1333, ddr3-1600, ddr4-2133). Generally speaking, the larger the memory is, the stronger the data processing ability is. The speed of data processing mainly depends on the type of memory (for example, DDR is not as fast as DDR3). Generally, 9 large-scale games (pubg, battlefield 5, Russian fishing, call of ty 16, etc.) and large-scale software (PR, AE, etc.) will occupy a lot of memory. Therefore, for game players, the higher the memory, the more games they can play
3. The motherboard is mainly composed of processing chips. For example, the notebook i965 is more powerful than i945 in processing data, and the i945 is more powerful than i910 in processing data, and so on. And 3 and better motherboard can also adapt to a more powerful CPU (central processing unit)
4. Hard disk is divided into solid state hard disk (SSD), mechanical hard disk (HDD) and hybrid hard disk (sshd). The speed of SSD is the fastest, followed by hybrid hard disk and mechanical hard disk is the worst. The larger the hard disk, the more files it can store (such as movies, music, etc.). First of all, the data reading and writing speed of the hard disk and the rotation speed of the hard disk are divided into high-speed hard disk and low-speed hard disk. High speed hard disk is generally used in large servers, such as 10000 rpm and 15000 rpm; Low speed hard disk is used in general computers, including laptops). Desktop computers generally use 7200 rpm, and laptops generally use 5400 rpm. This is mainly e to the accidental scratch of hard disk disk e to the moving vibration of computers, as well as the power consumption and heat dissipation of high-speed hard disk in laptops
the speed of hard disk varies with different interfaces. Generally speaking, it is divided into IDE and SATA (commonly known as serial port) interfaces. In the past, most hard disks were ide interfaces. In contrast, the access speed is slower than that of SATA interface. 8
with the development of the market, the cache of hard disk has increased from 2m to 8m, which is 16m or 32m or larger. Just like CPU, the larger the cache, the faster the speed
5. Graphics card: pay attention to the stream processing ability of the graphics card, the size and bit width of the display memory. The bigger the better. This is directly related to the response speed of running super large program software, such as running cad2007, 3dstudio, 3dmax and other graphics software, and playing large-scale 3D games, such as pubg, Russia fishing 4, battlefield 5, call of ty 16 and so on. In addition to the hardware level differentiation, there is also the "shared memory" technology in the graphics card. Different from the general self-contained memory chip, the "shared memory" technology needs to read the memory from the memory,
