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.
the arrival of digital currency is an inevitable requirement under the background of the great era , and the central bank's digital RMB has the nature of legal compensation. Digital RMB does not pay interest, and can be used in small, retail and high-frequency business scenarios. there is no difference with paper money and because of the legal compensation, we can't refuse to accept the central bank's digital RMB. Moreover, the digital currency Research Institute of the people's Bank of China says that it can realize the circulation of digital currency between different clients in the transaction process by means of technical solutions, generating new digital currency and canceling old digital currency
after being excited for such a long time, it turned out that it was just an oolong. However, some people said that this warm-up is likely that the digital currency will soon be issued and used. What's the use of digital currency? Is it the same as WeChat Alipay? In this regard, Wang Jian, chief analyst of Guoxin Securities financial instry, believes that the number of Renminbi and banknotes and coins are RMB cash. Alipay, WeChat payment and so on are just a payment tool. Through these two channels, the balance of personal bank card is still used, or the credit card is being brushed, and the digital Renminbi payment is used. What we spend directly is digital RMB, just like cash
3. Look at the indivial requirements for the accuracy of quantification. What comes out of big data analysis is that the success rate must be higher. Digital currency is still very little to quantify, now it seems that jiuzhuang bcbot is doing quantification. For reference, in a bear market, high-frequency trading will surely be more reliable.
4. Digital currency is still very little to quantify. It seems that Mars asset bank is doing it. You can refer to it first
5. If the property is cheated, it is necessary to report to the public security organ in time. The public security organ determines the nature of the case after examination. For those who meet the conditions of filing a case, it is necessary to obtain evidence by means of investigation to solve the case, so as to recover the loss of the victim
legal basis:
166th proceres for the handling of cases by public security organs. The public security organs should give immediate acceptance to citizens for the transfer, reporting, accusation, reporting or criminal suspect's automatic surrender, inquire about the situation, and make notes. After checking correctly, the signers, the complainants, the accusers, the informants, and the automatic surrendered persons will sign their names. Print your finger. When necessary, it shall be recorded or videotaped
Article 174 if, after examination, administrative punishment is not enough for criminal punishment, it shall be dealt with in accordance with the law or transferred to relevant departments
Article 175 after accepting a case, if a public security organ, upon examination, considers that there are facts of a crime that need to be investigated for criminal responsibility and that the case belongs to its own jurisdiction, it shall file the case with the approval of the person in charge of the public security organ at or above the county level; If a person considers that there is no criminal fact, or that the criminal fact is obviously minor and does not need to be investigated for criminal responsibility, or that there are other circumstances in which criminal responsibility is not investigated according to law, the case shall not be filed with the approval of the person in charge of the public security organ at or above the county level
if the public security organ decides not to file a case with a accuser, it shall make a notice of not filing the case and deliver it to the accuser within three days
187th, the public security organs should investigate the criminal cases that have been registered in time, collect and obtain evidence materials of the suspect's guilt or innocence, light offense or heavy crime.

6. Fake. All transactions involving digital currency are frauds. You don't have to think about the use of RMB to buy the so-called digital currency.
7. Any market can achieve high-frequency trading, but the high-frequency trading cost requires hardware support such as bandwidth server, as well as algorithms for different markets and different periods. Arbitrage trading is really suitable for digital currency, and now the well-known strategy is hummingbird strategy (HMT. One).
8. Bitcoin high frequency trading is legal. Because the domestic bitcoin trading platform does not charge for spot trading, the trading volume is relatively large, and a large part of it is high-frequency trading. On December 5, 2015, the central bank and other five ministries and commissions jointly issued the bitcoin risk notice, which defined bitcoin as a special Internet commodity. People can buy and sell bitcoin freely at their own risk. But I don't quite understand what you said. Some netizens told me this before. The operation mode is like a pyramid scheme. It's similar to the on hook of spark entertainment bitcoin reported by bitcoin home. Specifically, I am not very clear, I hope the majority of netizens to be vigilant, in order to prevent being cheated.
9. Digital currency exchange depends on several aspects. 1. Team. You can see if the team of the exchange is professional enough. For example, bitmex's team is mainly from Internet companies, while hopex's team is mainly from traditional financial institutions. 2. What kind of trading mechanism does the exchange adopt? Now the more recognized trading mechanism is perpetual contract, which can guard against sudden burst of positions and so on. Bitmex and hopex, for example, all adopt the perpetual contract mode. When they can trade for 7x24 hours, 365 days and the whole year, it is difficult to burst their positions suddenly. 3. Technology. In fact, the technical strength of trading platforms is also very important, so we need to see if they can support multi frequency trading volume and a large number of visits. At present, bitmex and hopex have reached the frequency of millions of transactions per second.
