Raspberry Pie 3 CPU mining power

1.

mining chip has gone from CPU mining to GPU mining to FPGA mining, and now it has entered the era of ASIC mining. However, the way of mining has also experienced from one or two mining machines to small mining machine workshops, and now it has entered the era of large-scale mining

(1) mining mode: from one miner to large-scale mine

if you start to try mining, you need to prepare a miner, a computer with internet connection, an AUC, a raspberry pie, power supply and various connecting cables. 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

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

mining difficulty improvement at present, our machines can meet the market demand

3. Hello, fire coin Pro is a trading platform for users to trade, mining is not supported. You can store ADA in fire coin account for transaction. If you want to store your currency for a long time, you can withdraw it to your wallet. However, you need to consult the customer service of the relevant wallet for the specific wallet security.

4. Yes, AMD's latest CPU, do not refuse, you can check online, the current CPU seconds kill everything

5. No, you can register without a recommender's account. I don't know which platform you want to register
it is suggested that you play on the big platform, not on the small platform. You will lose money sooner or later,

7. Coal mine underground transportation gateway generally refers to the raw coal transportation roadway; The track gateway is usually used as the auxiliary roadway for transporting materials when the fully mechanized working face is arranged with "three roadways". In most cases, the belt conveyor (belt conveyor) is mostly arranged in the transport chute roadway, at this time, the belt conveyor has no direct relationship with the track chute. I understand that your question mainly refers to how to simplify and optimize the design of fully mechanized working face with "two lanes" layout. First, it is necessary to simplify and optimize the support, driving mode, driving type, driving cycle and driving technology of roadway design based on the geological structural conditions of coal seam; Second, we should focus on the coal mining technology, coal mining methods and layout of coal mining equipment; third, we should strengthen the hydrological and geological prediction of the fully mechanized working face and its surrounding areas; Fourth, fully considering the installation and transportation of fully mechanized mining equipment, reasonably arranging the technical parameters of roadway formation based on the maximum size of fully mechanized mining equipment; Fifthly, the quantity of work needed for equipment replacement, compressed air supply, water supply, drainage and improvement of various systems should be considered; Sixth, it is necessary to reasonably allocate the relationship between the recovery equipment and the ending conditions of the mining face after the ending.

8. Usually the temperature is not too high. If you don't have static electricity on your fingers, you can touch the CPU. It's about 50 degrees. It shouldn't be too hot. Pay attention to heat dissipation in summer. Don't support it in too hot environment. If the temperature is too high, add a small fan. CPU temperature view does not seem to have this function. You need a sensor on the chip.

9. Chinese Name: Chia: Chia
every piece of income: 64 Chia awards every 10 minutes halving strategy: one in three years, 4chia every 10 minutes from the 13th year

in Chia's network, there are no miners, mining, but farms, farmers, sowing. By introcing a new consensus mechanism, POS + pot (proof of space + proof of time), we can verify its blockchain with cheap, rendant and highly dispersed unused hard disk storage space, so as to create a digital currency superior to bitcoin
Chia network is a decentralized open source global blockchain. Compared with the traditional workload proof cryptocurrency, it is less wasteful, more decentralized and more secure. Its inspiration is similar to bitcoin blockchain, but in Chia, the resource is not computing power, but disk space. In order to achieve this goal, the "work proof" used in bitcoin is replaced by "space proof", so disk space becomes the main resource and time proof to reach a decentralized "Nakamoto smart" consensus to verify transactions. Chia network is also an intelligent trading platform company. On March 18, 2021, Chia network officially released Chia 1.0 main network with XCH token, and has opened mining (farm) activities
Chia's working principle
different from the existing cryptocurrency, Chia uses the idle disk space on the hard disk to run the proof of space, and coordinates with another consensus algorithm, potime, to verify the blockchain. The income of Chia farmers is directly proportional to the amount of resources storage space; If you have 10 times the space, you will get 10 times the reward. But the post here is different from filecoin and the mining mechanism of bitcoin. CHIAS uses spare disk space to sow, just as bitcoin uses computing power to mine, V; Bbkx008, but Chia is more suitable for ordinary users to participate, recing the additional ASIC, computing power and power consumption. Chia's mechanism naturally inhibited centralized seeding<

summary of Chia's common problems:
can I continue to plot if I shut down or quit the software accidentally
No, we can only do it again

parallel P several graphs, what if I don't set the time interval
if the time interval is not set, plot will fail. Generally, the interval of at least 10 minutes is set

can I dig my notebook
as long as your SSD is more than 330gb, you can dig, but I don't recommend you to use notebook SSD. Notebook SSD has a lifetime, and enterprise SSD on desktop is recommended. There is enterprise SSD performance summary excel in the group
When did this coin start digging? It was launched on the main network on March 18. Open the transfer function 6 weeks after the launch
is there any application for this Chia

at present, there is no
can I find someone to replace my P-map and sell me a mechanical hard disk full of writing
I don't recommend it, because the picture of P is associated with the wallet, so you need to send the wallet and the picture to you. Do you think it's safe for two people to memorize words in their hands

do I need SSD when I'm full of mechanical hard disk
No, you can take out the mechanical hard disk, connect it to the idle computer, and mine on the Internet, even to the raspberry pie
