Blockchain online course

1. blockchain can make money in the following ways:
first, R & D and proction
as the source of blockchain technology application, in the field of R & D and proction, there are three main forms:
1. Coin making: using blockchain technology to solve some traditional problems. This mode is the mainstream of blockchain instry entrepreneurship, which is commonly seen in some start-ups, Their solutions often provide some tokens to support their development, so I call it mint for short. For example, cloud storage tries to solve the problem of cloud storage by issuing token SC; Bitstocks provide a decentralized exchange and issue token BTS; Press one wanted to try to reconstruct the content ecology and issued a token PRS. This mode, with the booming of blockchain investment market this year, especially ICO, has also brought huge market value to start-ups. It is possible that a blockchain project has been valued at hundreds of millions of Yuan before its specific procts are listed. For example, the current market value of EOS is more than 400 million US dollars
2. mining: assist the mint team to proce tokens. If Mint is to develop a new type of token, mining is one of the specific means of proction. However, not all tokens support mining. Only coins with pow (proof of work) mechanism support mining. The most famous one is bitcoin. Mining efficiency is closely related to computing power. At present, it is basically large-scale mining, and it is difficult for ordinary people to participate. In addition, mining is not the only way to proce tokens, and investment risk is relatively high
3. Outsourcing: to provide technical solutions in the field of R & D, another mode is to provide blockchain solutions for teams without blockchain technology capabilities
around this emerging technology, there must be more and more similar projects. As for whether it is reliable, we should be more careful. Summary: on the whole, in the field of R & D and proction, it is more suitable for organizations to enter, and there is limited space for indivials to dig for gold, so here is a brief overview< Second, financial circulation
no matter what kind of token comes out, it will always circulate, so there is a lot of demand in the financial field. For an organization, there are two common practices:
1. If there is a demand for trading, there is a demand for trading website. Although the transaction fee is cheaper than the stock, when the transaction is frequent, the transaction fee is rich enough. After several years of development, there are many trading websites on the market. However, if we look at the long-term development of the blockchain instry, the current number is probably not enough. Most importantly, judging from Jimi's current experience, most trading websites are not satisfactory. It's either a temporary outage or a visit to Caton. The recharge efficiency is low. In the era of mobile Internet, there is no app... The more places users feel uncomfortable, the more opportunities they have. There are two forms of trading websites. One is for the trading of listed tokens, such as bitage, cloud coin, China bitcoin, etc; One is to raise ICO for new projects, such as crowdfunding, icoinfo, ico365, etc
2. For fund investment, if 2C is used for trading website, 2b is used for fund investment, with high threshold. There are mainly two forms: venture capital and investment in various blockchain start-ups. This kind of fund requires more capital threshold, of course, the return is the real equity. Participating in pre-ico means participating in token raising before ICO. The advantage is that you can buy tokens at a lower price. If the project is good, the return is amazing. Compared with venture capital, this kind of investment requires less capital
for indivials, the threshold is much lower. There are mainly three ways:
1. ICO
you can understand it as a new issue in the stock market, and you can hold tokens at a lower cost. When the market is good, token listing can get dozens of times of growth. Even if there is no good market, the cost is relatively low later, which is a relatively safe way of investment
2. Currency speculation
just like trading stocks in the Shanghai Stock Exchange, buying and selling tokens in major exchanges is the most common way of investment for most people, which is generally divided into spot speculation and futures speculation, which will not be repeated here
3. Move bricks
unlike stocks, a token can be used on multiple platforms, including domestic and foreign. Due to the different game situation of each exchange, it is difficult to keep the same price of the same currency in different exchanges, which in fact leaves room for spread arbitrage. Of course, with the increasing number of brick movers, the price gap will be quickly flattened. What's more, moving bricks also faces many risks, such as exchange rate, handling charge, market fluctuation and so on. Now it's more and more difficult. Summary: compared with R & D and proction, many retail investors have entered the financial sector
thirdly, as an emerging instry, peripheral support has many opportunities to make money besides R & D, proction and financial circulation
1. Tools
because blockchain is close to money, people pay close attention to it. Around its daily use, a lot of tools are needed. Take a few common cases: market inquiry: This is almost a must for many investors every day, which has proced solutions in various scenarios, such as the price search robot in wechat group, the global index of blockchain in small programs, and the sobtc in app. Security: after all, it's gold and silver. Security is also the focus of every investor's attention. For example, Google identity authentication, Taiyi passport, etc. are tools for security
2; Forum
an emerging field, there is always a demand for information and communication, so there is media; The needs of the forum. For example, the official account of the media area, the "vernacular block chain" that hatched out of the small circle is a typical case. In less than 1 months, the target of 0 to 10000 powder has been completed. Around the blockchain content, in addition to we media, we can also make websites, forums, audio, video and even live broadcast. As far as the current observation is concerned, the market has not yet formed a monopoly, and there is still a lot of room for the market. 3. Content payment
because the instry is too new, there are few related content procts. There are several things to do:
1) as an emerging investment proct, investor ecation is a little understood by many investors about blockchain, resulting in a lot of learning needs, At present, there are two common ways: online class mode: listen to the music through a piece; Qianchat and other courses popularize the knowledge of blockchain, such as the previous lessons of laomao. Community model: carry out investment practice and communication through small secret circle (now renamed knowledge planet), such as Jinma's small secret circle
2) as mentioned in the developer training, one of the ways to make money in R & D field is coin making, and the technical talents needed for coin making are urgently needed in the market. Therefore, offline, there are many training courses for blockchain technology, which are not reliable. In addition, this is really a big market
3) if the first two types of instry research reports are aimed at indivials, then most of them are aimed at some enterprises.

2. There are no mandatory regulations on the payment of housing provident fund, which is the deficiency of the regulations on the administration of housing provident fund
Article 13 the management center of housing provident fund shall set up a special account for housing provident fund in the entrusted bank
the unit should go to the housing provident fund management center to register the payment of housing provident fund, and after the approval of the housing provident fund management center, go to the entrusted bank to go through the proceres for the establishment of housing provident fund accounts for the employees of the unit. Each employee can only have one housing provident fund account
the management center of housing provident fund shall establish a detailed account of employees' housing provident fund to record the deposit and withdrawal of employees' personal housing provident fund
Article 20 the unit shall pay the housing provident fund on time and in full, and shall not pay the housing provident fund overe or under paid
for the units that have difficulties in depositing the housing provident fund, the deposit proportion can be reced or postponed after the discussion and approval of the staff congress or trade union of the unit, the examination and approval of the housing provident fund management center and the approval of the housing provident fund management committee; When the economic benefit of the unit improves, the deposit ratio shall be increased or the payment shall be postponed
Article 37 in violation of the provisions of these regulations, the housing provident fund management center shall order the unit not to go through the registration of housing provident fund deposit or the proceres for the establishment of housing provident fund account for its employees within a time limit; If it fails to do so within the time limit, it shall be fined not less than 10000 yuan but not more than 50000 yuan.

3. In the future, the development trend of the media instry will be to realize the vertical integration of various segments and realize the collectivization of the media. However, there are many bottlenecks in the film instry. For movie creators, the problem of infringement and piracy that can not be eradicated all the time can be well solved by using the blockchain technology with tamper proof characteristics. At present, there is a public service platform called blockchain for movies and plays in China, which is initiated by Hunan souyun technology and Hengdian cultural exchange. It seems that it is just doing this.

4. In my opinion, if you don't have 2 years or more programming background, you will have a hard time learning blockchain. Of course, unless you are a master of computer science or a computer major graated from a very powerful University, that's another matter. The development of blockchain technology is not very different from Java development. The programming logic is the same. The reason why it takes two years is to let you master the programming logic solidly. Then when you learn blockchain, you can move to the past relatively easily. Your brain power is greatly reced and you will not be so tired

at that time, the blockchain instry was very hot, many people signed up, and the national policy was also very concive to the development of the blockchain instry. They also had a technical background. It was better to learn than not to learn, so they went to school with this utilitarian speculative mentality. It's on the same line. The training institutions are not big, but the teacher resources are really hard. They all graate from famous universities, Tsinghua University, Chinese Academy of Sciences, University of Chicago and so on. I won't tell you which one, so as to avoid the doubt of advertising. At that time, I asked for a period of time after the annual leave, especially to learn this technology
the course is relatively easy for me. Of course, I can't represent many people. My classmates have both seniors and children who have just entered the technical post. Needless to say, our acceptance of the course is not the same. Basically, people with five years of experience can easily keep up with the teacher's ideas. If it's 2-3 years old, the teacher will have to think about it after he has finished speaking, The course is above their level, but you can get it with a jump
the course cycle is 14 days. In the first two days, it is easy to accept the basic knowledge. Later, there will be actual combat. This is not only the difficulty of learning, but also the standard to test whether you master it. Fortunately, the teacher began to teach step by step operation, so we can basically pass the actual test
in the morning and afternoon, we have a theory class, and in the evening, we consolidate the theory through experiments. There will be questions and answers in the middle of the class, and there will be comprehensive questions and answers every week. The curriculum is reasonable, the intensity is medium, and there are many gains after learning every day. Frankly speaking, it's hard to feel this feeling since I went to work. After 14 days of persistence, I passed the graation examination, got the diploma, and mastered a skill that may reconstruct the world in the future. My heart is satisfied and firm< To sum up, my experience is for your reference. My advice to you is to accumulate at least one year's work experience and then learn blockchain technology. You will feel that it is still easy to learn at that time. Or you can go to the Internet search to see if there are blockchain online courses. If there are any, you can contact them in advance. The online course will definitely not require you to finish all the courses in a period of time and explore slowly, It may also be a learning path.

Python learning path

the first stage is Python foundation and Linux database. This is the beginning stage of python, and also an important stage to help students lay a good foundation. You need to master Python basic syntax rules and variables, logic control, built-in data structure, file operation, advanced functions, moles, common standard library moles, functions, exception handling, MySQL use, coroutine and other knowledge points

learning objectives: master basic Python syntax and basic programming ability; Master the basic operation commands of Linux, master the advanced content of MySQL, and complete the projects of bank ATM system, English Chinese dictionary, lyrics parser, etc

the second stage is full web stack. In this part, you need to master HTML, CSS, JavaScript, jQuery, bootstrap, web development foundation, Vue, flag views, flag template, database operation, flag configuration and other knowledge

learning objectives: master the web front-end technology content, master the web back-end framework, skillfully use flash, tornado, Django, and complete the data monitoring background project

The third stage is data analysis + artificial intelligence. This part is mainly to learn the knowledge points related to crawler. You need to master the knowledge of data capture, data extraction, data storage, crawler concurrency, dynamic web page capture, scrapy framework, distributed crawler, crawler attack and defense, data structure, algorithm, etc

learning objective: to master crawler, data acquisition, data organization and algorithm advanced and artificial intelligence technology. It can complete crawler attack and defense, image mosaic, movie recommendation system, earthquake prediction, artificial intelligence project and other stage projects

The fourth stage is advanced. This is a python advanced knowledge point. You need to learn project development process, deployment, high concurrency, performance tuning, go language foundation, blockchain introction, etc

learning objectives: master the technology of automatic operation and maintenance and blockchain development, and complete the automatic operation and maintenance projects, blockchain and other projects

according to the python learning roadmap above, you can basically become a qualified Python development engineer. Of course, if you want to quickly become the elite talents of enterprises, you need good teachers to guide you, and you need more projects to accumulate practical experience

self learning itself is very difficult, and learning step by step is sure to be comprehensive and solid. If you want to learn which part, you can skip the targeted learning mole you don't need for the time being, and watch more different videos. The study time is generally 5-6 months

6. Recently, many students preparing for the MBA have asked me what difference the MBA can bring, which has also aroused my thinking. As a past person, I plan to write an article to tell you about it. I don't want to talk about the improvement of social network and knowledge system. I want to talk about some changes that have taken place in us. Let's give a few examples to show the changes in our way of thinking more appropriately:

1. Investment related: Recently, when considering investing in some real estate, I was extremely anxious about real estate before I went to MBA, and I didn't know the reason for the increase when I saw the changes in house prices, It's just that it's too late to buy any more. This idea is almost the same as that of the market. It's not that it's bad, but that it's not clear what's going on and it's time to make a decision; After reading the MBA, I will think about several things: 1. The premise of thinking is to judge the economic environment, the changes of GDP in the world's top ten in the past 20 years, how many years of golden period can China have against the developed countries, and how the asset prices fluctuate in the golden period (I will not analyze in detail here), so as to get a judgment of the trend for the better; 2. I will compare myself to a company. We can see that the way small companies turn into large companies is not to make profits and put them into proction, but to increase the asset scale and debt scale by enlarging assets (M & A, investment, etc.). Companies that do so become large companies, such as blue cursor. We are all grassroots and "small companies", If we can make it bigger, the result of my thinking is to make the assets bigger, leverage and increase the debt ratio. Only in this way can we realize the class transition; 3. Compared with Hong Kong, Seoul, Tokyo, Los Angeles and other cities, it's common for the core area to have a house price of 200000 yuan per square meter. You can see the future changes in Beijing (I'm not an advocate of house prices, just an analysis), and then you can make decisions
2. Career development related: many people want to help their career advancement by taking the MBA. Before they took the MBA, many people thought that they could get to know more people or have a good ecation to find a good job, which is career advancement. But if it's so simple, it's too easy to succeed. After reading the MBA, my thinking is to consider the following aspects: 1. Instry selection. Take grassroots as an example, we have nothing. We work hard to earn hundreds of thousands of dollars a year and work overtime every day, but we don't know what we should do. For grassroots, I propose to enter the latest instry, regardless of whether we understand it or not, and whether the past experience is useful or not, Go straight in, because only in this field do you have fewer vested interests. You may become the future vested interests, but you have to enter early. Only when others are not optimistic about you can you have the opportunity to enter
for example, in the blockchain instry, in addition to the above reasons, it's instry practitioners. Many of the people I contact with in this instry have very general ability. I'm also thinking about why the practitioners in the new instry have weak ability. The conclusion is that the gods in the original technology field and financial field don't care about it at all, and the cost for those with vested interests in the original instry to jump out to do it is too high, So most of the people in this instry are barefoot and not afraid to wear shoes. Once your ability is really outstanding, you can create a lot of value; When new things appear, don't deny the value. First, see why they can be recognized by a few people; 2. Enterprise choice: everyone is shouting that their income is low and the company is squeezing them. But have you ever thought that the value you create is only so much, and money is the most direct measure of value. I see that the annual income of good professionals increases by 30% to 50%. What you want to think about is what kind of companies can achieve this income increase? It's very simple. It's very easy for a company with an annual growth rate of more than 100%. Should you open 36kr or it orange to see which companies are in this category, and then try one by one; This is what I think MBA should have
3. About self-improvement: the improvement before MBA is basically in the work, you can see the specific scope of your own work from the perspective of vision, you don't think about the company's strategic thinking at all, and you don't know how to supplement yourself; After reading it, I graally began to think about the root causes of influence on people. I had to study theology, philosophy, psychology, NLP, success, and so on. Finally, I found that the core is the same, but some need to understand and some need to experience through training. Today, there are many new models, such as superindivial, leap, and so on At this time, I will think that all Tauren should have their own values and thinking methods, and be able to know all the decisions of work and life, so I put forward the value oriented thinking mode, which can be applied to life and work, and I am also the practitioner of this thinking mode; It's not enough to have a theoretical system. You need a lot of people to recognize your thinking. You need to operate Zhihu, Zhixing and other high knowledge platforms to expand your influence, so that you can create more value
today, I will talk about these three aspects first, and I will continue to write about these topics in the future. From a practical point of view, MBA has brought about changes in people. There are many unprofessional aspects. I hope you can correct me.
