Mining principle of virtual currency
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin more quickly and make profits
bitcoin has a halving effect, that is to say, every four years, the number of bitcoin will be halved. In this way, the computing power of bitcoin will increase, that is, the difficulty of mining will increase. Under normal circumstances, mining generally refers to the use of mining machine, that is, the computer to dig. These all refer to the single operation, or the operation of the whole mine. Cloud computing power mining refers to mining with multiple people. You can participate in mining as long as you invest a small part
the usual steps of bitcoin mining are "purchase miner - deploy miner - set miner - get profit", but the deployment of miner is affected by many factors, such as electricity price, site, temperature, noise, operation and maintenance, etc. These barriers need certain conditions and knowledge to eliminate, so it gives birth to a sub mole of mining instry - cloud computing power
cloud computing power is a remote mining mode. Users purchase cloud computing power contracts through the platform, rent computing power mining, and obtain revenue regularly. The advantage of cloud mining is that users don't need to deeply understand the mining principle and various software and hardware, or buy expensive mining machines, and they don't need 24-hour maintenance. As long as they place an order, they can participate in mining, which is similar to purchasing usufruct procts
for mine owners, renting and selling the right to use the computing power for a period of time to customers at a price slightly lower than the self operated mining income can quickly return cash, purchase the latest mining machinery in advance, expand the proction scale, and win the possibility of profit in the forward market. To some extent, it can also retain mining machinery at a low currency price, transfer risk, and hedge the single risk of self operated mining business< However, compared with direct participation in mining, cloud computing power also shows the following disadvantages:
even if the platform fully displays relevant information such as mines, mining machinery, cooperation and teams, it is still difficult for users to judge the quality of computing power, real-time operation status (such as power failure, site temporary inspection) or real revenue data behind the platform
the risk of speculation in bitcoin (short-term trading to earn spread) is higher than that of Tuen bitcoin (long-term bullish), but most Tuen bitcoin investors often lack judgment on short-term price changes and "get off early". Cloud computing power brings a small amount of bitcoin income to investors every day, which is also controlling investors' frequent operation in disguised form. Therefore, for many people who like bitcoin, there will be such a saying: "it's better to dig money than to fry money"
the market opportunity of cloud computing power is to provide indivials with a more neutral way of investment. The threshold is lower than that of self built mines, the risk is lower than that of short-term operation, and the cost is lower than the market price. It also allows mines to share the costs and risks and obtain more abundant cash flow
the main risk of cloud computing power lies in the authenticity and stability of computing power behind the contract. In our long-term contact with the mining instry, the high-frequency words we hear are "pit": reasons for power failure beyond common sense, various incidents ring the transportation of mining machinery, constant interference of viruses and extortion, fluctuation of futures and tardy spot, obstacles of cross-border trade, and team ghosts that can't be prevented. Therefore, real and stable computing power is scarce to a certain extent, Behind it is often years of experience. As an information intermediary, cloud computing power platform will become its core competitiveness in how to help users select high-quality cooperative mine cooperation, design friendly and attractive procts, formulate professional and transparent instry standards, establish disaster recovery plans to deal with various risks, and provide high-quality services throughout the whole process of investment
of course, mining is a long-term development instry, and cost recovery also needs a certain period, so whether you can make money mainly depends on whether you can stick to it.

famous leaders of student affairs in Colleges and universities who teach us the ideological and political work in typical colleges and universities
there is an introction about the student work of the key universities of the Ministry of ecation
there is an outstanding representative of counselors working in the front line like us, the national excellent assistant director Li Qin
the training course enables us to receive all-round training in all aspects< During the training period,
we also participated in two forums and two visits to Northeast Normal University, which enhanced our communication and knowledge< Through the training, I have the following experiences, which are reported as follows:
first, I fully realized the importance of counselors' work, understood the relevant background and policies of the state in the ideological and political work in Colleges and universities, and was encouraged
Xu Yanguo, director of the ideological and Political Work Department of the Ministry of ecation, pointed out in the training, The team of counselors is the personal guard of the party and the state, and the task of counselors is to train qualified socialist builders and reliable successors<
"it's easy to get a good teacher,
it's hard to get a good teacher"
,
this sentence puts the role of counselors in the work of ecating people in a lofty position,
as a counselor, we should not only teach students to survive,
but also teach students to be human beings,
it's extremely noble to be a tutor and good teacher< As a teacher who has direct contact with students' study and life,
counselors' speech and behavior not only affect the formation of students' Outlook on life,
world outlook,
values,
but also affect the growth of students< Therefore,
college counselors must fully understand their responsibilities,
further enhance their sense of honor,
sense of responsibility and historical mission,
take on the sacred mission of cultivating excellent talents for the party and the country,
promoting the prosperity and development of the motherland< At the same time, director Xu pointed out that in order to thoroughly implement the spirit of the opinions of the CPC Central Committee and the State Council on Further Strengthening and improving the ideological and political ecation of college students and effectively strengthen the construction of college counselors,
the Ministry of ecation formulated the
regulations on the construction of college counselors on May 20, 2006, which put forward the orientation of college counselors. College counselors are both teachers and administrators, organizers, implementers and instructors of students' daily ideological and political ecation,
they are intimate friends and life mentors for the healthy growth of college students< According to the regulations, counselors should account for a certain proportion in the evaluation and employment of university teachers, the evaluation criteria should be independent, the evaluation criteria should be in line with the actual work of counselors, and the achievement identification should be flexible< Director Xu pointed out that in the future, the Ministry of ecation should organize regular training for counselors in combination with the improvement of their comprehensive quality, and organize the selection of national excellent counselors, so as to create a good platform and environment for the growth of counselors< In combination with the Ministry of ecation '
24
orders, director Xu showed us the importance, background and future development of counselors' work.
the Ministry of ecation's training for college counselors and the training for college counselors in the whole province organized by the research base fully illustrated the importance that the state and higher ecation departments attach to the work of counselors and students,
feel much more drum
dance, more energetic< Second, we should fully realize that we should improve our ability and quality to adapt to the student work in the new period. How to meet these new expectations and requirements and solve the problems existing in the current
student work is a problem that must be faced up to and urgently needed to be solved in order to do a good job of College Counselors in the new period< Through the explanation and teaching of relevant leaders and experts in the training process,
I deeply realize that the counselors in the new period are not the former nanny counselors,
fire brigade counselors and management counselors<
contemporary counselors should understand the importance of their work,
deeply understand and master the knowledge of mental health,
be familiar with the characteristics of the working group,
implement the party's major policies into the student work,
be an expert counselor,
only in this way can
have the ecational effect on students. After listening to the reports of experts, I deeply realize that
I have many shortcomings in student work
these deficiencies include,
insufficient cognition of students,
insufficient level and structure of self-knowledge,
insufficient ability to solve students' psychological problems,
insufficient ability to keep pace with the times and do a good job in students' work,
insufficient theoretical literacy. In the future work, we must face up to these shortcomings,
be determined, planned and step-by-step to supplement and improve, make up for the deficiencies, improve their ability and quality,
strive to be a qualified college counselor,
adapt to the needs of the post,
meet the new requirements and expectations of the majority of students in the new period and new stage
three, fully aware of the advanced nature of the instructor's model, and realize that there is a big gap between
training course. We invite the national excellent counsellor and the national excellent student Huang Lai daughter's counsellor
ring the training, experts have repeatedly mentioned the last national excellent counselors
Fudan University "forgive me", and I was deeply impressed by the touching deeds of the two excellent counselors<
1
, to be a conscientious person
"words of inclusion" is the epitome of the work of an ordinary college counselor, her behavior is very ordinary,
very ordinary,
it can be said that as long as a counselor who has been with students for four years, she will experience the trivial work of inclusion,
as long as she has a little sympathy and a little sense of responsibility
responsible teachers will sincerely pay for the students,
every senior
school counselor has a certain writing ability at the same time,
but why is there only one
inclusive heart language
only one inclusion? It shows that we are not living with our heart,
working with our heart
of course,
we can say that there are too many
trivial tasks that make us have no time,
especially when there are large-scale activities or important periods,
we don't even have time to sleep,
but we can't do it every day, every week, every month,
including diary,
I believe she doesn't have so much time to write diary,
what she wrote was weekly notes
this shows that inclusion is a person who has a heart of
and a heart of
life, he will certainly have a heart of work,
in order to serve the students well in his work,
lead the way<

, be a person without regret and selfless dedication
Li Qin put forward his theory of paratroopers in his report: if a person asks a paratrooper, you may be surrounded and arrested by the enemy as soon as you fly,
aren't you afraid? The paratrooper replied:
we paratroopers were born surrounded
- we want to be people who have no regrets,
we want to be people who give selflessly
I think it's very vivid and appropriate for counselors to
talk,
we should agree< The story of Li Qin and his classmates helping Huang Lainu and his father selflessly in his report has infected everyone,
this kind of help has surpassed the level of teachers and students,
and even the level of relatives, which shows that he has fully understood and applied the theory of paratroopers to his work practice.
Last week, a paragraph about bitcoin became popular:
bitcoin broke through 5800 US dollars (about 38280 yuan) . When it was issued in 2009, 1 US dollar was equivalent to 1300 bitcoins. What is investment? It has increased by 7.54 million times in 8 years. At that time, you spent 38000 yuan to buy some bitcoin. Now you are the richest man in China, surpassing Xu Jiayin, who has 290 billion yuan
but just one week later, on October 20, bitcoin broke through the $6000 mark. Although it fell later, it reached more than $6000 again on October 21, reaching a maximum of $6147. In terms of $6000, bitcoin prices have risen 7.8 million times in eight years
according to cryptocompare, a bitcoin data provider, e to China's strict supervision of cryptocurrency trading, the global share of bitcoin market has been greatly changed. Now, in the total trading volume of the world's bitcoin exchanges, the trading volume of RMB versus bitcoin accounts for about 1.6%
} the proportion of RMB and yen in global bitcoin trading volume (photo source: cryptocompare)
the reporter noted that in the first half of this year, after Japan's legislation recognized bitcoin as a legal payment method, bitcoin's trading volume in Japan surged, and Japanese regulatory authorities have issued certificates to 11 cryptocurrency exchanges. About 58% of bitcoin trading currently takes place in the Japanese market, and nearly a third of yen to bitcoin trading takes place on the bitflyer exchange in Tokyo. In addition, the U.S. and South Korea markets also account for a large part of global bitcoin transactions - the U.S. dollar and the Korean won account for 27% and 7% of the total bitcoin transactions, respectively< br />
first of all, your computer should be installed with the latest version of bitcoin client. After opening the client, all transaction information data on the network will be automatically downloaded to the local. Depending on the network speed, this process may take several hours. At this time, the account balance is 0. Users can ask friends to send some coins, but a more feasible way is to do mining or merchant acquisition<
mining as a miner
to be a miner is to proce bitcoin with one's own computer. In the early client, the option of mining is still available, but it has been cancelled. The reason is very simple. With more and more people participating in mining, it may take several years for one to dig 50 coins. Therefore, miners generally organize miners' guild to dig together. Specific mining methods, you can go online search
as a businessman, you can buy coins g by miners with money, open an online shop to sell things and collect bitcoin, and even go to the exchange to speculate in coins. There are many websites providing bitcoin exchange services, which can be converted into almost any kind of currency. If you really don't know how to exchange, you can also come to laoan for help
the difficulty of bitcoin mining is directly proportional to the amount of money that has been mined. The more difficult it is to mine, the more difficult it will be. After 20 million bitcoins are mined out in 2030, the remaining 1 million bitcoins will probably take decades to be mined out. And bitcoin has no central issuing authority, which is generated by network nodes through complex calculations. Anyone can run bitcoin software on a computer to make it. During circulation, enter the quantity 1 on the client software, then come to the other party's bitcoin address and sign with the payer's password. After that, the bitcoin is the other party's.
the principle of bitcoin and dogcoin is that different types of mining options only use different software. Does the mining of virtual currency sound much more complicated than the mining in the general sense? In fact, it is not difficult to understand. The simple meaning of virtual currency mining is to let the graphics card carry out mathematical operations and allocate virtual currency according to the percentage of the amount of calculation. How does virtual currency survive in financial market? Since the birth of digital currency, there are several elements supporting its ecological chain, and they can not carry out mining transactions and payments. The way to obtain virtual currency is also inseparable from mining
any store trading with cryptocurrency does not need to pay taxes, nor does it need a lot of capital management fees. The international circulation is very convenient, and it is a very popular currency transaction mode for people and merchants all over the world. Without the control of the central bank, the quantity is limited and can completely resist the pressure of inflation. So as to maintain and increase the value of the common people's wealth
mechanical watch is a kind of precise metal instrument, some of which are even more accurate than medical tools. Therefore, there is no need to worry about whether there is a running in period in use. In fact, there is no running in period. The only thing we need to pay attention to is the rational use of mechanical watch, which is the best guarantee for its movement and quality
