at present, according to the official income method of fil, there are three ways: one is to provide hard disk storage to obtain income (storage miner), the other is to provide bandwidth resources to obtain retrieval income (retrieval miner), and the third is mining and packing block income (storage miner). Based on the above rules, only enterprise level and cloud mine pool can meet the three kinds of income at present
In terms of configuration, based on mining rules, the following configuration suggestions are given:CPU: 4 cores or above, Inteli series is the best, memory is at least 8g, if you want to get retrieval revenue, memory needs more than 16g, hard disk space is recommended to be more than 4T to get storage revenue

household mining machine (current situation analysis, There are the following disadvantages:
A. more than 95% of domestic IP addresses are not static, which leads to mining default platform withholding pledge tokenB. you need to buy pledge token, and you need to spend some extra money to buy token to start
C. the sound of power outage is loud, and the events affecting neighbors lead to no income
D. unfortunately, your family is in the second, third, fourth and fifth tier cities, Basically, we can't get the order
e. the home miner advertised by a Yingkuang machine can't mine and can be retrieved. The retrieval needs an uplink bandwidth of at least 10m, and the space-time proof (IPFs anti cheating mechanism) may need a higher stable bandwidth of more than 20m. Who's community's network can meet the above requirements within 24 hours, so the retrieval is also very difficult
It is said that the investors who started brainwashing and bought the household miner in March of 18 bought a small box at 5-10 times the price and put it at home as a decoration, so the household miner is used to cut leeks, because it has a low threshold, and then you can hardly dig fil -
Enterprise trusteeship miner
a, In terms of hardware configuration, the cost of setting up a mine is relatively high. If the leasing meets the national application conditions, the purchase price of a single configuration combination is about 3-10 times of the cost price, which is relatively high
B. the same computer room is generally leased to multiple enterprises for storage and application, which will lead to multiple operating systems running at the same time, Lack of unity, easy to be attacked by hackers
C. vicious competition of all mining machines in the mine, internal consumption of computing power, unbalanced order distribution, resulting in some machines grabbing orders and some machines not having orders, and Unbalanced Income
D. different independent IPFs mining machine systems, it is difficult to unify parameter grabbing orders in real time
E. unable to resist regional policy risks, For example, the national policy risk
F. the biggest advantage of enterprise level is high configuration, centralized basic management, and room conditions are superior to household mining machines. At the same time, the above situation is accompanied by

cloud mining pool
A. computing power leasing, the price is relatively low for hosting mining machines, The leasing time is controllable
B. the IDC rooms of general cloud mine pool are defense class, which can prevent hackers from intruding
C. the output of the mine pool is shared throughout the network, and there is no worry about the failure of a purchased node, and there is no income
D. the hardware input is allocated throughout the network, and the personal input-output ratio is cost-effective
E. unified scale management, and there is no single node debugging, Single maintenance status
D. node layout is generally multi city and multi country, regional policy risk
E. third party real-time monitoring, high degree of information disclosure, always know the output status of ore pool
F. unified operation and maintenance system, real-time unified parameter adjustment, pricing strategy, order grabbing strategy, storage strategy

for the above analysis, At present, the existing cloud mining pools in China, such as a cat cloud mining pool, a Yingyun node, an inter cloud mining pool, and a chain cloud mining pool, claim to be globally distributed in the publicity. After actual verification, their mining pools are either small private mines established by themselves or professional mining machine trusteers cooperated in China, and most of them are limited to China, Because the construction cost of the mine pool is very high, and the cost of cooperation with domestic cloud service providers is even higher, we should set up our own small mine pool to publicize the global layout
currently, it is recommended to learn about "Noah cloud pool". After verification, the channel cloud service providers of Noah cloud pool are currently cooperating in Hong Kong, Singapore, Germany and Poland, and their technical background is relatively strong. Please check other relevant information
After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites
in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution
as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners
extended data:
handling charge:
bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)
because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction
at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress
however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain
in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer
if you want to create a virtual currency like bitcoin, Ruitai coin and Qianjin card, you need to make some efforts. First of all, these coins need card method and a downloadable wallet. The application scenarios of this kind of currency have been determined. At the same time, you need to create a secure and reliable trading platform.
POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbersextended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

POC consensus mechanism integrates the advantages of pow / POS / dpos, and achieves better coordination of decentralization, efficiency and consistency in different directions, which are difficult to unify in blockchain< br />
1. Decentralization: in the POC consensus mechanism, there is no rigid limit on the number of nodes. The number of nodes is dynamic, and anyone who meets the conditions can join the nodes. Here, each outgoing node is similar to the mine pool in the pow, and can join the consensus in the mine pool by holding interests. In the pow, the pool obtains the bookkeeping rights according to the computing power. In the POC, the chance of all the pools to obtain bookkeeping rights is random and equal, which makes the node distribution of the consensus mechanism of POC more decentralized< br /> < br />
2. Efficiency: the two key factors affecting the efficiency of blockchain network are the degree of wide distribution of nodes and the hardware network resources provided by nodes. In the coordination of these two parameters, POC consensus mechanism introces the credit coefficient mechanism, which directly affects the stability of the node. Therefore, each node and the principals participating in the node will make the most favorable choice for the network to ensure that the node can provide services efficiently and stably. In addition, they will join the node consensus by means of rights and interests, The number of nodes will float in a certain range, which can be adjusted by changing the incentive parameters. When the parameters are fixed, the market will adjust automatically. In these nodes, the dpos principle of random sorting out blocks is integrated, which ensures the security and efficiency of the network and provides higher TPS carrying capacity< br />
3. Consistency: in the POC consensus mechanism, all members can participate in the consensus, and the node can only charge a certain fee to the participants. All people have equal opportunities to participate in the consensus, and the incentive is determined by the equity and node credit coefficient. Nodes and all participants will reach a consensus in order to provide stable node services.
the cost of a mine includes construction cost, equipment cost, maintenance cost, network cost, etc. The maintenance cost includes the cost of electricity and manpower, which is why we will build the mine in a place with relatively low electricity charges. The payback cycle of a bitcoin miner is related to many factors, such as policy, technology, currency price, computing power, maintenance status and so on. It generally takes 200-300 days to payback. But as the market fluctuates, so does the cycle
with the mine, let's talk about the mine pool. As more and more people are now engaged in mining, more and more mining machines and mines are added, and the total power is growing. In this case, the probability of a single miner digging into bitcoin is getting smaller and smaller. So, people came up with a way. Since mining machines can't do it alone, we can combine mining machines to compete with other mining machines in the world - the collection of computing power of mining machines is the so-called mine pool. In this way, the probability of mining can be greatly increased. When bitcoin is g, corresponding rewards will be given to each miner according to its contribution to the total computing power
the concept of mine pool is more abstract than mine field. The ore pool can be a collection of several mining machines, or a collection of computing forces of mining machines in a number of mines. For example, when it comes to a mining pool in China, the mining machines connected to the pool include both Chinese and foreign mining machines, which are distributed according to work regardless of region.
