1. Of course, this is OK
first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.

3. 👉 A: cloud wallet is not a blockchain. It is a pioneer of free sharing of bookkeeping rights
- what's the purpose of playing bitcoin
you will give 100 reasons, but the real purpose of most people is only two words: to make money<
only a few people participated in the early stage. They felt that the financial system of Wall Street was stealing itself, which triggered the subprime mortgage crisis and made Americans pay for the greed of Wall Street. As a result, they have developed a machine accounting system that is separate from the Wall Street accounting system. In other words, people who are not for the purpose of making money (early BTC players, positioned as competitors on Wall Street) have gained economic freedom. The purpose of the late participants is to make money. As a result, most of them lose money
- why do those who hope to make money lose money, while those who do not hope to make money make a lot of money instead
reference answer: the choice of competitors determines your position
others take Wall Street as their competitors and are at the top of the tower. Wall Street and the new financial promoters are at war, and pawns are injured<
- the competitor of cloud wallet is the Federal Reserve, and its bookkeeping logic is the same as that of the Federal Reserve
the bookkeeping logic of the Federal Reserve: Liabilities of others = assets of self, and all creditors' assets are paid by corresponding debtors
the accounting logic of cloud Wallet: Liabilities of public network = human assets = future services provided by public network = AIC. Similarly, all creditors' assets are paid by corresponding public network
blockchain and bitcoin, compared with the accounting system with the Federal Reserve as the core, are just like mountain bandits. People who get rights don't want to take on obligations. Each blockchain has its own way, and there are many factions in the mountain
cloud wallet is a regular army model, which relies on the efficiency advantages of accounting system and public network to expose the inefficiency and corruption of the US dollar system
cloud wallet has seven software engineers at present, and only 700 software engineers will be needed in the future to meet all the needs of global bookkeeping, trading and settlement. This efficiency is more than 3 million times higher than that of the Federal Reserve's bookkeeping system, which is maintained by hundreds of millions of financial practitioners. Cloud wallet is to give the right of choice to human beings. When human beings choose cloud wallet, the 20 trillion interest difference saved each year is the value created by everyone's leisure time. It is also the basic value of AIC
- in the cloud wallet system, you are a general and the public network is a pawn; In the blockchain system, you are a pawn, and the early players are generals.
- in the cloud wallet system, everyone can transform labor, proction capacity and services into super capital without legal money. In the blockchain system, there must be a large number of leeks.
- in the cloud wallet system, the world factory can be directly transformed into the wealth of the Chinese people, The world factory is not worth money at all
- the cloud wallet framework can hold the whole world, including the people behind the Federal Reserve and wall street; In the framework of blockchain, most people can only be reced to leeks
- cloud wallet framework, which takes time back to 2009, so that everyone can dig out the equivalent of bitcoin (gold stock) with their own leisure time and intelligence
- the general is up, the pawn is down! What is your choice?

4. In view of the security characteristics and shortcomings of the existing blockchain technology, we need to build a security system around the physical, data, application system, encryption, risk control and other aspects to improve the security performance of the blockchain system as a whole
1. Physical security
the network and host running the blockchain system should be in a protected environment. According to the regulatory requirements of specific business, the protection measures can be used to protect the physical network and host by means of VPN, firewall, physical isolation, etc
2. Data security
in principle, the data exchange between nodes of the blockchain should not be transmitted in clear text. For example, asymmetric encryption can be used to negotiate key, and symmetric encryption algorithm can be used to encrypt and decrypt data. The data provider should also strictly evaluate the sensitivity and security level of the data, decide whether to send the data to the blockchain, whether to desensitize the data, and adopt strict access control measures
3. Application system security
application system security needs to start from the aspects of identity authentication, authority system, transaction rules, anti fraud strategy, etc.
relevant personnel, transaction nodes and transaction data involved in application operation should be controlled in advance and auditable afterwards. Taking financial blockchain as an example, consensus algorithm with stronger fault tolerance, anti fraud and higher performance can be adopted to avoid joint fraud of some nodes
4. Key security
to encrypt the communication data between the blockchain nodes and the key to encrypt the data stored on the blockchain nodes, the plaintext should not exist on the same node, and the private key should be properly saved by the encryption machine. When the key is lost or leaked, the system can identify the relevant records of the original key, such as account control, communication encryption, data storage encryption, etc., and implement response measures to make the original key invalid. The key should also be managed strictly in the life cycle, and should not be permanently valid. It needs to be replaced after reaching a certain time cycle
5. Risk control mechanism
there should be careful detection measures for the network layer, host operation, data access of application system, transaction frequency and other dimensions of the system. For any suspicious operation, alarm, record and verification should be carried out. If illegal operation is found, loss assessment should be carried out, remedial measures should be taken at the technical and business levels, and security measures should be strengthened, And trace the source of illegal operation to prevent further attacks

5. A paper by Ja. It should still be very authoritative. Maybe I didn't make it clear. In addition, when I look at some parts of the tutorial, it is also mentioned that if the multicollinearity problem is solved, it can be achieved through "data centralization". But why? What is the principle< In order to rece the multicollinearity caused by the interaction between the continuous variable "experience / reason oriented understanding process" (in this study, this variable is an independent variable) and other independent variables "picture type", the independent variables were treated with mean centralization in the regression< br />
“Because indivial difference is a continuous variable, the hypotheses tests used multiple regression analyses. To rece problems with multicollinearity among the continuous variable (experiential–rational processing) and its interaction term with the other variable (picture type), the independent variables were mean centered for the regressions.

6. Before answering this question, it is necessary to understand what chain reform is, because it has a lot to do with the business the company is engaged in“ "Chain reform" refers to the economic transformation of the block chain of traditional joint-stock enterprises, the use of block chain technology to enable them to operate on the chain, by helping enterprises issue token, reconstructing a benign closed-loop ecosystem and providing a stable application circulation platform, to help enterprises gather consensus, so that more stakeholders (including enterprises, employees, investors, middlemen, enterprises, etc.) participate in the creation of enterprise wealth End users all have the right to co govern and share the long-term interests of enterprises, and change the traditional joint-stock companies into distributed autonomous organizations under the blockchain economy, so that enterprises can obtain more and more consensus and create greater value in the co governance and sharing of interests
according to the relevant Internet search results, the company's main business is to help small and medium-sized enterprises to make chain reform. With the deep integration of blockchain technology and enterprise's real economy, the company uses blockchain thinking, reconstructs the enterprise's business model on the basis of understanding and combining the enterprise's current business model, and helps enterprises to design reasonable token model and token development It also provides a safe and efficient platform for the exchange of corporate certificates to build an interest consensus body integrating enterprises, employees and users, and solves the financing, sales and other practical difficulties faced by enterprises in the realization of the innovation of financing mode and interest distribution mode, so as to achieve the landing application of blockchain in the real economy
in addition, according to the relevant data of tianyancha, the company has obtained qualifications, including the "regulatory sandbox demonstration application unit" awarded by the regulatory sandbox Department of China Strategic Planning Institute, the vice president unit awarded by the regulatory sandbox Committee of China Electronic Energy Saving Technology Association, and the "strategic cooperation unit" awarded by the national instrial information security development research center, At the "2018 China Economic Summit Forum" held in Beijing in December 2018, it was rated as the top ten innovative enterprises of China's economy in 2018. Judging from these qualifications, the company has a certain strength background. In terms of the development trend of the blockchain instry, its business layout is consistent with the current national policy layout and the general direction of advocating blockchain to serve the real economy. It should have a good development in the future.
