1. Concept analysis of blockchain: it is not only a concept but also a technical system
blockchain is a distributed system, which is constructed by cryptography. Indeed, blockchain is a technical collection of concepts formed by distributed system and cryptography. We should emphasize that it is not only a concept but also a technical system, At the very beginning, blockchain only represented the account structure of the underlying technology of bitcoin. It was a narrow concept. At the beginning, because the development of this technology should be represented by a special term to distinguish it from bitcoin, this word was used to refer to it, and it became a bigger and richer concept and a complete system
when we think back to cloud computing, cloud computing existed before the word cloud computing was put forward. However, once cloud computing was put forward, it developed rapidly along the concept of cloud computing. I think blockchain also has such characteristics, and it will continue to develop. Once it becomes a complete sub Technology system, all the technologies in the sub fields under blockchain will continue to develop, The algorithms in the sub domain will develop in the direction of qualitative change in the way of adding tests. Blockchain is a kind of distributed line or network trust technology. When I studied blockchain technology, there was no blockchain word. We called it distributed computing. On the technical level, end-to-end. From a macro point of view, the blockchain is composed of multiple nodes participated by Dongfang. It is equal. The cooperation of these nodes needs to complete the mutual verification on the blockchain. At this time, there is no need for a central node to do this
macro: distributed equal deployment system, participating nodes cooperate to complete verification and storage
microcosmic: rigorous data structure is packaged and stored in the block, and logically concatenated to form a chain
digital signature and integrity verification ensure the authenticity, real-time and timing of block data
at last, after learning all the technical features, it has achieved the multi fight, informed group and supervision right, because it is transparent, shared and open. All parties of the alliance should participate in the operation of the blockchain system, which is equivalent to a co construction, sharing, sharing and co governance. When constructing the alliance, I have to think of one thing: what I store to the blockchain, which are transparent and which are encrypted. At this time, I need to determine according to your business system. If someone deliberately cheats, he or she will probably find that your data may be tampered or forged with the participation of the public or even the collective alliance, so he or she will consider the cost of doing evil. In this way, the trust cost of the alliance will be greatly reced, and there will be no friction. Outside the alliance, because you believe that you have adopted the blockchain technology, you will have a higher degree of trust in the services or procts provided by the whole alliance, so this is a very good way of virtuous circle
what should you do to build a blockchain system or to bridge business to a blockchain system? There are two steps, very simple. The first step is to construct several key roles in your business logic. Now consider how many roles there may be. There may be many roles, but now consider them as one. These perspectives must be related in business logic. They need to share and map these rules to the blockchain or put them into scripts at the same time. Next, we will talk about data, which data will be put into the blockchain and which will not be put, because the efficiency of the blockchain is security, which is generally simple and key, and only what needs to be built together is considered. On the other hand, even if some data are put into the blockchain, not all things need to be supervised, but may be closed door, and can only be seen after authorization, One is privacy, the other is regulatory compliance
after the first step, the second step is simpler. You need a convenient and reliable blockchain platform. It is an underlying infrastructure, including books, networks, supply and demand algorithms, and accounts. All these things have to exist. After general checking, you can check and send these four blocks according to your business needs. There is a protocol below. The above layer is mapping. This mapping layer is very important. It abstracts your business into many models and logics, and abstracts them into an easy-to-use system. Then you can develop your business logic on the application system, and then develop the business logic based on the blockchain. This is a fast process. In fact, a good blockchain business platform should have its own application tools, as well as monitoring, viewing and auxiliary tools, just like the early days of the database. At the beginning of the database, if it was just data without auxiliary tools, it would be very difficult to run
next, let's share a small case, which is the case of blockchain business points that we just released. There are a lot of views that we have already discussed. We must use points to make it universal, so that consumers can get profits and businesses can rece the burden. Moreover, we can let points flow and guide real secondary consumption. This is of great significance. We have to consider more when we choose commercial competition. Commercial competition itself has a certain financial or monetary attribute. It is a purely low-risk number, because it has the lowest regulatory risk to the extent of compliance and legality. Second, points can quickly accumulate digital assets, accumulate C-end users, test your blockchain platform to a certain extent, and even test your blockchain technology to verify whether your blockchain platform is right. Finally, derived with financial related attributes, for the expansion of financial means behind all laid a good foundation
according to the path of building a blockchain system that we have just seen, the first step is to make decisions. In the blockchain system, it plays two roles: merchant and consumer. Merchants are also divided into two levels, the points they send, the points they receive, and the points they receive are also divided into two levels, the points they transfer out and the points they receive. Rules are non discrimination rules; Data, integral, some data are very interesting. I can write all the people on it, and I can write the effective information on it. There are some consumer behaviors, such as what to buy, coffee or bread. These data are written on it. I will use a simple example to guide you
the second step is to find a platform for blockchain. In our Bubi blockchain, what do we get? We really got a positive feedback. We think it's a very good feedback. First, digital integral represents a variety of data assets, which can be supported on the blockchain. Second, it may have many users, whether real users or laboratory simulation users. It's no problem to support millions of transactions and storage. Third, it really builds a good foundation for us, which lays a good foundation for the exploration in the financial field.

2. Bet in wechat group? No app? Now many news reports about wechat group fraud. It's too unsafe. When the wechat group is disbanded, who do you want to get the money from.
3. Ideally, securities trading does not need transaction intermediary, and it is highly efficient to directly go from indivial to indivial, or from institution to institution, or from institution to indivial.
4. Python digital currency quantitative trading advanced course, has been learned, generally mastered.
5. Common stock
common stock refers to the shares that enjoy common rights in the company's operation and management, profit and property distribution, and represents the claim on the enterprise's profit and resial property after meeting all claims for repayment of creditor's rights and the claims of preferred shareholders. Common stock is the basis of company capital and a basic form of stock. At present, the stocks traded on Shanghai and Shenzhen stock exchanges are common stocks
ordinary shareholders enjoy the following basic rights according to the proportion of their shares:
(1) the right to participate in the decision-making of the company. Shareholders of common stock have the right to participate in the general meeting of shareholders, and have the right to propose, vote and vote. They can also entrust others to exercise their shareholders' rights on their behalf< (2) the right of profit distribution. Common shareholders have the right to receive dividends from the company's profit distribution. The dividend of common stock is not fixed, which is decided by the company's profit situation and its distribution policy. Only after the preferred shareholders get the fixed dividend can the common shareholders enjoy the right of dividend distribution< (3) stock option. If the company needs to expand and issue additional common shares, the existing common shareholders have the right to purchase a certain number of new issued shares at a specific price lower than the market price according to their shareholding proportion, so as to maintain their original proportion of ownership of the enterprise
(4) the right to distribute the remaining assets. When the company goes bankrupt or goes into liquidation, if the assets of the company remain after paying off debts, the remaining part will be distributed in the order of preferred shareholders first and common shareholders later
preferred stock
preferred stock is relative to common stock. Preferred stock has priority over common stock in terms of the rights of profit distribution and resial property distribution< (1) priority of distribution. When the company distributes profits, the shareholders with preferred shares distribute prior to the shareholders with common shares, but enjoy a fixed amount of dividend, that is, the dividend of preferred shares is relatively fixed< (2) priority claim. If the company is in liquidation, the preferred shares will be distributed before the common shares when the remaining property is distributed. Note: when the company decides not to distribute dividends for several consecutive years, preferred shareholders can enter the general meeting of shareholders to express their opinions and protect their own rights.

6. The EDR model is very simple. It mainly depends on the amount of money held. The re investment is once every seven days, so there are not many skills. The main number is 100usd, and the next is a trumpet
7. We need to understand some mathematical models, such as statistical analysis, artificial intelligence algorithm and so on. Its essence is to use mathematical models to analyze the potential laws of data, find trading opportunities, and use computer programs to search for trading opportunities and complete automatic trading. There is no ready-made software to do this, because it needs to build a professional platform, which is not a person can complete
there are some domestic software, such as great wisdom, which provides quantitative analysis, and some software which provides programmed trading of stocks and futures. But in fact, this is not a real quantitative transaction. In fact, it is very difficult to make a pure quantitative investment software suitable for indivial investors, because the quantitative strategy does not have the established and inevitable law like the traditional fundamentals and technology. He needs to cross multi-disciplinary, multi field to mine the rules of data, and then use the rules to trade. However, the potential laws of different time and space data are not consistent, so it is difficult to standardize the quantitative process
if you are a computer or math professional, you can consider using C, C + +, SQL and other languages, and other software such as MATLAB / SAS. No matter what kind of software, to achieve quantitative trading, it must need a certain modeling basis and programming basis, among which the most important thing is mathematical ability.
