73t cloud miner

1.

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

2. There are many kinds of mining machines in the market, and the currencies they dig are different. Bitcoin machines are the most. From Shenma m3 and ant S9 to many computing power machines, customers have more choices. The computing power is getting bigger and bigger, and the price of machines will rise correspondingly. There are many small currency machines coming out, so if you are just starting to contact this instry, You can choose a BTC digging machine with high cost performance, and buy one or two back as a reference. If you suggest, you can choose ant S9 or core T2T, with computing power of more than 10 t to 30 t, and the price is less than 1000 yuan

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

4. This mining company not only claims to be the largest mining pool node of IPFs in China, but also has joined the first official test node of filecoin. They still said in the meeting that their mining machine can dig 20 filecoins a day, big liar.

5.

IPFs is a file transfer protocol similar to http. If IPFs wants to run, it needs many computers (storage devices) in the network as nodes. In a broad sense, all participating computers can be called IPFs mining machines

in order to attract more users to join the IPFs network and contribute to the network, an encryption currency named filecoin is designed, which is distributed to the participants (nodes) as a reward according to the amount of contributed storage space and bandwidth. In a narrow sense, the computer specially designed for the purpose of obtaining the filecoin reward is called IPFs mining machine

because IPFs network needs storage space and network bandwidth, in order to obtain the highest profit ratio, IPFs mining machine usually strengthens the storage space and reces the power consumption of the whole machine. For example, more than 10 high-capacity hard disks are equipped, Gigabit or higher speed network cards are equipped, and ultra-low power architecture processors are used

of course, the mining machine provides storage services, so it can obtain revenue. The size of revenue is related to the configuration of mining machinery and the number of IPFs mining machinery

extended data

the reasons why it is not recommended to invest in IPFs are as follows:

1. IPFs technology is too early to be commercialized

IPFs now takes up a lot of bandwidth. IPNs is very slow at present, which is an obvious technical defect. It will be very difficult to realize dynamic web pages only through IPFs

There is no reasonable economic model, even if the token economy is added, it is difficult to realize the long-term natural ecological value

as a very cumbersome decentralized protocol, it is difficult for users to share files autonomously and spontaneously. In addition, even if users share files into the protocol, the files will be completely open and users cannot delete files effectively, so the security of valid files is threatened

the solution is to introce encryption and blockchain incentive mechanism. At the same time, it solves the security and storage power problems of files. However, as mentioned before, any node with workload proof under blockchain incentive mechanism will face an economic problem of continuous power on state

It is difficult to establish an ecological network with IPFs as the core under the influence of technical problems

The ecological application space of

IPFs is quite limited, and the project interaction speed realized by IPFs protocol is also very slow. Of course, it has a direct relationship with the number of nodes and the distance of calling

6.

The price of IPFs mining machine ranges from 2000 to 70000. It mainly depends on the configuration you choose and whether it corresponds to the warranty period of mining machine. Of course, the hype, but the actual miner is also very poor, so we need to identify

in the IPFs mining machine market, the most popular star Aoyun mining machine is more than 20000 with two years to buy back

however, IPFs has not been launched yet, and we only look forward to it because the cost performance ratio of mining machinery is relatively high. We can only see how much can be proced by one machine a day

IPFs mining machine

7. Depending on the configuration, interstellar Aoyun has three IPFs miner models: AOU as12t8, AOU as24t8 and AOU as36t8. This depends on the number of hard disks (total capacity). The price should be between 10000 and 20000. For details, you can go to their official website and ask customer service.

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours

the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)

mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home

the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine

the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
