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.

as part of the blockchain, the regulatory authorities (central bank, China Banking Regulatory Commission and China Securities Regulatory Commission) can obtain the public account books of P2P transactions in real time, and obtain the financial management projects and capital transfer information of each P2P enterprise by analyzing the public account books, so as to provide low-cost, efficient and reliable regulatory data for the supervision of P2P instry in real time Second, the borrower's credit transparent blockchain is mainly to solve the credit problem, so the blockchain is the most promising application in credit investigation. However, there are many controversies about credit information. After all, the data related to credit information is very sensitive. Both credit information institutions and users do not want to make it public. Data is the lifeblood of credit information institutions. Every family wants others to make it public and keep it secret. Users also don't want their data to be public. Of course, if we can achieve the transparency of credit investigation in the future, it will be very beneficial for P2P investors Third, the transaction structure of low-cost for a P2P platform, the monthly withdrawal fee of users is not a small expense, but the general P2P platform will pay this part of the fee out of their own pocket. It is a good thing for the P2P platform to apply the powerful online transaction function of blockchain, go to the third party payment, or bank fund custody, and complete the fast, prepared and transparent transaction of funds
3. 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

4. Generally speaking, the essence of blockchain should be weak control, sub center, autonomous mechanism, network architecture and coupling connection. The essence of blockchain should be a new social structure in the era of information society, which is completely different from the instrial society. The five core points of blockchain are in common with sharing economy to some extent. The essence of the sharing economy is to abandon the old development mechanism, no longer focus on concentration, and instead use the decentralized social resources in a point-to-point way to let the participants participate in, and pay and benefit in different ways
the two Internet hotspots, blockchain and sharing economy, happen to have sufficient "cooperation space". With the development from theory to practice, the instry has made a lot of bold explorations about the two, and even some challenges to the traditional business model have emerged. In this way, the sharing economy with blockchain will be a new business model and a new subversion of interpersonal relationship. I plan to invest in the blockchain instry. After all, in the Internet era, I searched Guangzhou Xuanling Technology Co., Ltd. on the Internet and looked at the webpage. They are a company engaged in software blockchain intelligent contract development. There are many development cases, and the team is also strong.

5. The real name authentication system of qubu app is connected with aliyunn. The information required to be filled in is only compared with alidatabase, and there is no security problem
6. Because blockchain is characterized by "decentralized, trustworthy and independent value"
for example, two people who don't know each other can check whether they can be trusted or not through the historical bookkeeping function of blockchain
if they can be trusted, transfer transactions can be generated directly instead of through the bank or payment platform

7. A lot! Finance, project application and human resource management are all resources that can be shared. Please pay attention to "SMIC blockchain service platform" for details
8. It depends on how you look at it
the essence of sharing economy is to share information and resources seamlessly, directly and efficiently among strangers, so as to create value beneficial to both sides. To achieve this goal, the prerequisite is to trust each other and know the root. But since they are strangers, where does mutual trust come from? As a result, platforms that provide a sense of trust and promise fulfillment emerge as the times require - airbnb, Uber and didi taxi are among the best. By building and maintaining technology platforms, they aggregate, reorganize and allocate scattered resources and demands, verify the true identities, professional qualifications and background information of suppliers and demanders, provide transaction information, payment tools and comment records, and finally facilitate the transaction between the two parties
in the future of sharing economy, we must open up the channel of mutual trust at the indivial level, and blockchain is the key to open the channel. Sharing economy model is a new business model with P2P as the center, while blockchain is an innovative digital technology that drives comprehensive P2P transactions. Both of them expose their own loopholes and risks, and have great room for improvement and a long period of improvement. Blockchain and sharing economy can be mutual partners or competitors. Whether it is an enemy or a friend depends on the attitude and perspective of the authorities - whether they should take the initiative to consolidate and strengthen their advantages by taking the initiative to embrace each other, or whether they should wait for the day of marginalization? Airbnb, the leading enterprise of sharing economy, chose the former
decent can also be regarded as a kind of sharing economy project or a blockchain project.
