HKC blockchain mode

1. Currency transaction
currency transaction is mainly aimed at the transaction between digital currency and digital currency, in which one currency is used as the pricing unit to purchase other currencies. The currency transaction rule is also to complete the matching transaction according to the price priority and time priority
C2C transaction
both sides of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the Seller shall make payment according to the reservation. When the transaction is completed offline, the platform, as an intermediary, charges a certain percentage of the handling fee from each successful transaction
OTC OTC trading
is a set of offline purchase digital currency platform independent of the exchange. Anyone can publish purchase / sale advertisements on the platform. The purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer.

2. The explanation of MIIT is as follows: blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
take an example: for example, Sun Tzu asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head for notarization and added the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization
in addition, you can refer to bitcoin, the representative proct of blockchain

3. First of all, blockchain itself has no business model to speak of
you are talking about the combination of blockchain technology and an instry. That is to say, "blockchain +" combines technology and instry deeply after combining specific projects to develop corresponding landing applications
the technical characteristics of blockchain and its application fields
① data can't be tampered with. Blockchain is a decentralized distributed database without centralized server, which can't be controlled by a certain person or an organization. Each node in the blockchain system stores one of the data. If the data on the node is changed, the blockchain system will be able to store one of the data, Then it can not be verified in the whole blockchain network. With this feature, it will be well used in finance, public administration data, audit data, etc
② distributed storage: in the area fast chain system, each running node has a complete data , which enables each node to independently verify and retrieve data, greatly increasing the reliability of the system. Combined with the characteristics of this blockchain technology, it is applied to games. We are familiar with the fact that our games are applied to a game server, It can greatly increase the stability of the game and enhance the game experience of the players.
③ anonymity. Traditional software clients need to register a user name and bind the mobile phone number. In order to increase the user's recognition, some will also increase the identity authentication. Combined with the blockchain technology, they are converted from the public key generated by the public cryptographic algorithm, This is usually a string of garbled characters. Bitcoin system is like this, but we don't know who is the operator behind it.
combined with this technical feature, we can make use of online payment, collection, property on the chain, etc. to greatly protect the user's information.

4. Energy compensation e s is a good blockchain project, which can be paid attention to

5. BP neural network has the ability of arbitrary complex pattern classification and excellent multi-dimensional function mapping, which solves the exclusive or (XOR) and some other problems that can not be solved by simple perceptron. In structure, BP network has input layer, hidden layer and output layer; In essence, BP algorithm takes the square of network error as the objective function, and uses the gradient descent method to calculate the minimum value of the objective function.

6. This project has nothing to do with bitcoin, just under the guise of bitcoin<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.

7. According to the specific needs, the current blockchain can be divided into the following categories according to different classification standards. Before cooperation, we must pay attention to the strength and effect of the team. When we understand the baker chain blockchain, it has a good evaluation in the instry, good reputation and good performance in all aspects.

8. Voice of the Century Group has cooperated with Jiajin He technology company to complete the development and application of the latest global traceability tracking system for wangbingqian Jingui liquor, wangbingqian Honggui liquor and wangbingqian langui liquor. The application is linked to the ant financial services blockchain and can be tracked and inquired around the world. Just pick up the mobile phone close to the wine box sealing chip, that is, all the information of Wang Bingqian wine will pop up automatically. From Maotai Town winery to Guiyang packaging workshop, and then to the distribution center and logistics route, all at a glance. Blockchain traceability technology ensures the safety and effectiveness of all information, and no one can tamper with it, ensuring the absolute authenticity of every bottle of wine.
