Filecoin miner graphics card

1. Although filecoin has not been officially launched, the parameters of the miner have not been determined. However, filecoin mining based on IPFs technology is a new battlefield full of opportunities. Of course, excellent miners have to take the lead. Let's understand what kind of configuration filecoin mining needs& lt; div>& lt; div>& lt; h2>& lt; b> 1、 Network broadband & lt/ b>& lt;/ h2>& lt; p>& lt; b> 1. Have up and down line bandwidth& lt;/ b>& lt;/ p>& lt; p> Because IPFs needs to download data from other nodes on the network, and also provide upload data service to other nodes, it has special requirements for uplink bandwidth and downlink bandwidth, so it must have uplink and downlink peer-to-peer dedicated bandwidth before mining& lt;/ p>& lt; p>& lt; b> 2. Set a public static IP address & lt/ b>& lt;/ p>& lt; p> Filecoin mining, we must ensure a stable access speed, now office and home broadband are generally dynamic IP, need to go through N layer ISP conversion, can not guarantee the normal access between remote servers. In order to ensure the efficiency of mining, it is very important to set a static IP address of public network& lt;/ p>& lt; h2>& lt; b> 2、 Hard disk storage & lt/ b>& lt;/ h2>& lt; p> Although there are two ways for filecoin mining, the most important thing is hard disk storage mining. After all, bandwidth mining requires very high network transmission, and this kind of large-scale traffic download and upload channel is not what ordinary miners have& lt;/ p>& lt; p>& lt; b> 1. High capacity hard disk & lt/ b>& lt;/ p>& lt; p> The larger the capacity of hard disk, the greater the potential and ability of filecoin mining. If it is affected by the price of hard disk, we can also increase the number of hard disk to meet the requirement of large capacity& lt;/ p>& lt; p>& lt; b> 2. Compatibility & lt/ b>& lt;/ p>& lt; p> Since we want to increase the number of hard disks, we should pay attention to the compatibility design of hard disks. It is necessary to ensure that hard disks of different brands, capacities and performances can be put together in a harmonious way. Only in this way, the utilization rate of hard disk will be improved, and the work efficiency of miners in the later period will be greatly improved& lt;/ p>& lt; p>& lt; b> 3. Work 24 hours a day & lt/ b>& lt;/ p>& lt; p> Since the choice of hard disk mining method, data download and storage are 24 hours running. If all data is lost e to the quality of the hard disk itself, then the mortgage token will be confiscated by the system, so we should consider this aspect when choosing the hard disk& lt;/ p>& lt; p>& lt; b> 4. Status display & lt/ b>& lt;/ p>& lt; p> Only when the hard disk has status display, can we clearly confirm whether the current hard disk is in read-write state, normal power on state, or fault state. In this way, it is helpful to find and replace the hard disk in time when there is a failure, which does not affect the effective mining work of the miner& lt;/ p>& lt; p>& lt; b> 5. Hot swap Design & lt/ b>& lt;/ p>& lt; p> Hot swap design means that the mining machine system supports hot swap hard disk, allowing the replacement of hard disk in the charged state, and will not damage the hard disk and data. This design can also improve the efficiency of filecoin mining and rece the probability of damage to mining machinery and equipment& lt;/ p>& lt; h2>& lt; b> 3、 Location & lt/ b>& lt;/ h2>& lt; p> The mining method of filecoin token will choose the principle of proximity& lt;/ p>& lt; p> From one point of view, if you have something to go out, you will definitely choose the nearest taxi to get on the roadside instead of crossing several streets to find a good-looking taxi to get on. This is how filecoin distributes mining& lt;/ p>& lt; p> Therefore, the geographic location of filecoin mining is best selected in the first tier cities for distributed layout& lt;/ p>& lt; h2>& lt; b> 4、 Hardware configuration & lt/ b>& lt;/ h2>& lt; p>& lt; b> 1.CPU</ b>& lt;/ p>& lt; p> The essence of filecoin mining is the storage server, which focuses on the I / O performance of the storage, and does not require high computing performance of the whole machine. Therefore, CPU only needs to meet the basic performance of mining machine& lt;/ p>& lt; p>& lt; b> 2. Memory & lt/ b>& lt;/ p>& lt; p> During the reading and writing of filecoin mining machine, the information is mainly stored in the memory temporarily. The size of the memory directly affects the reading and writing performance of the mining machine and the overall mining performance. In the economic conditions, the larger the memory of the mining machine, the better. It is recommended to choose the mining machine with Linux operating system and more than 4G memory& lt;/ p>& lt; p>& lt; b> 3. Network interface & lt/ b>& lt;/ p>& lt; p> The performance of filecoin mining machine is mainly reflected in I / O reading and writing. The low performance or small number of network interfaces will seriously affect the work and efficiency of mining machine. It is suggested that the home miner should be equipped with at least one Gigabit Ethernet port (RJ45 interface) as standard, and it is better to have two Gigabit Ethernet ports& lt;/ p>& lt; p>& lt; b> 4. Miner Design & lt/ b>& lt;/ p>& lt; p> Although filecoin mining machine configuration requirements are not high, but there are some places to pay attention to& lt;/ p>& lt; p> 1) Thermal design & lt/ p>& lt; p> Filecoin miner needs to work 24 hours a day. Of course, we should pay attention to the heat dissipation of hardware. Cooling design mainly depends on the fan, ct, and chassis. Pay more attention to this aspect when starting mining machine& lt;/ p>& lt; p> 2) Silent Design & lt/ p>& lt; p> After all, the miner is 24-hour operation, if the decibel of miner is too large, for a long time, people's mood will certainly become irritable& lt;/ p>& lt; p> 3) Dust proof design & lt/ p>& lt; p> It depends on whether the miner is professional or not. The st-proof design is one of the key indexes& lt;/ p>& lt; p> 4) Shockproof Design & lt/ p>& lt; p> The operation of the filecoin miner will definitely proce slight shaking. If multiple mining machines are placed in the same position, these vibrations will form resonance. Resonance is harmful not only to the hard disk, but also to the whole mining machine. Therefore, the filecoin mining machine needs to have a shockproof design.

2. Miner's moisture is relatively large, the main network code has not been finalized, miner will be determined first. Maybe after the main network goes online, we can't find money. There are also some supercomputing versions on the market, which can be understood as mining machines with a lot more than the normal configuration. This is a good way to deal with the total code changes of filecoin. But certainly not the most cost-effective mining machine. Make a good investigation and wait for you to test in the pit and Yuanli mine.

3. When choosing mining machine, it depends on the company's ranking on the test network. If it is not in the top five on the test network, it is recommended not to consider it.

5. The essence of mining machine is different
the essence of BTC / eth mining machine is data computing equipment
mining has developed from the initial personal computer mining, video card mining and personal mining machine mining at home to the cluster and professional large-scale mining. No matter from the initial CPU mining, GPU mining, or later FPGA mining, ASIC mining, large-scale cluster mining, its essence is to focus on improving the data computing capacity of mining equipment. The main internal parts of the mining machine are the power calculation board or graphics card, and the large cooling fan
the essence of IPFs miner is data storage device
the different essence of miner makes the configuration characteristics of storage miner very different from BTC / eth miner. The storage miner mainly used for data storage does not need too much computing power, that is, the performance of CPU is not required to be too high, and the memory capacity is suitable, but it needs a large capacity of storage space. That is to say, the density of hard disk per unit space should be large, and as many hard disks as possible should be equipped. At the same time, the I / O performance of data storage should be high, and the bandwidth channel should be as high as possible. Because of the special requirements of data storage, mining machine must be stable, safe and not easy to damage
filecoin officially announced that GPU is needed for mining. Although it means that computing power resources are also needed, the miners who use GPU get rewards for mining blocks. Most of them don't participate in mining blocks and only provide storage devices. They don't need GPU and can mine as long as they have a hard disk

7. Taking a bitcoin mining machine S9 ant mining machine as an example, the current price is about 9500 yuan (now it's estimated that it's not enough, but the algorithm is the same); The power is 1300 watts; After 24 hours of operation, 0.004549382 bitcoins (based on the current 19000 yuan per coin) are g out, with a value of 86.4 RMB. The mining machine needs 31.2 kwh of electricity to operate for 24 hours. It depends on your electricity price. If the electricity charge is 0.6 yuan per hour. Then, your daily income is 86.4 - 31.2 * 0.6 = 67.68 yuan, if the electricity charge is 0.35 yuan. Then, your daily income is 86.4 - 31.2 * 0.35 = 75.48 yuan, calculated by 0.3 yuan. A S9 miner needs 9500 / 77.04 = 126 days for static cost recovery [the result is not necessarily the same, but this is the calculation method]

8. The consensus of filecoin mining is replication proof and space-time proof. Space time proof needs to be completed in 45 seconds. The purpose of GPU configuration is to increase computing speed and complete space-time proof
Q and V have the same number, mining machinery and cloud computing business.
