Blockchain equity management system source code

1. Wangchain technology through the blockchain technology. The company's basic information, equity information, option information and other value information, as well as constantly changing information records and historical records can be included in the blockchain distributed ledger to improve information transparency and reliability. At the same time, it helps to match information between equity transferor and equity investor.

2. Now let's talk about the feasibility of blockchain equity crowdfunding in China. As we all know, as far as China is concerned, companies fall into two categories: joint stock companies and limited companies
joint stock companies are divided into "listed companies" and "unlisted companies". The shares of a listed company are registered in China securities registration and Clearing Corporation, so its behavior of issuing shares or trading shares is regulated by the CSRC. Here, we don't want to explain more; The shares issued by non listed companies do not need to be registered by any institution, and can be confirmed by issuing shares and maintaining the register of shareholders. Of course, many of them are registered through third-party institutions such as the instrial and commercial department or China Securities Depository and Clearing Corporation, and use the local share custody center to provide third-party registration services for publicity. Moreover, when the company's equity changes, it is necessary to manually process paper equity certificates, option issuance and convertible notes. In this way, the company's stock rights can be changed, The maintenance of the register of shareholders will become very complicated, and the tracking and maintenance of transactions will become more difficult to trace with more and more transactions
if the techshares blockchain technology is used for equity crowdfunding, all the above problems can be perfectly solved. The blockchain account book is safe and transparent, and can not be tampered with. It is also easy to track, and can record the company's equity and its change history at any time
convenience of equity transfer and circulation
for equity crowdfunding, equity circulation is an important part of business, which can stimulate the activity of users and promote more registration and issuance. The traditional OTC over-the-counter equity trading is based on the credit of both sides of the transaction, and the two sides of the transaction bear the credit risk on their own. The transaction can only be carried out after the establishment of bilateral credit, and the trading platform bears the credit risk of market traders
techshares blockchain technology can rece the credit risk of transactions. In essence, it decentralizes the third party that provides credibility to a more thorough extent, that is, it is no longer limited to specific third party entities, but relies on all participants to jointly maintain a set of registration system. On the one hand, blockchain gives the right to record to the company itself, reflecting the spirit of autonomy; On the other hand, it can also ensure the openness, transparency and authenticity of information records, and minimize rights disputes. The ownership of equity is registered in the blockchain, and the equity transaction must be signed by the owner's private key to be verified; After the transaction is confirmed, the change of equity will also be recorded in the blockchain, so as to protect the interests of both parties
how to ensure safety
as an investor, the most worrying problem is the safety of funds. Traditional equity crowdfunding often has the problem of "double flowers" (Note: double flowers - Double expenses, that is, the only share is repeatedly transferred to two people). Until the electronic data is comprehensive, the central clearing agency ensures that the whole system can be leveled after trading. But the risk is often borne by the platform. Unlike traditional floor trading, equity crowdfunding business is carried out by many independent companies. Therefore, these trading activities are scattered on various platforms. With the techshares blockchain technology, the decentralized trust constructed by the blockchain can ensure the normal operation of the system and business without the need for mutual trust. Everyone becomes a node in the blockchain, with their own public key and private key, participating in rapid transaction verification and accounting. Moreover, in the initial stage of equity crowdfunding, the sponsors, crowdfunding platforms, investors and sponsors jointly sign a crowdfunding contract to agree on their respective responsibilities and obligations. The contract can be stored in the blockchain in the form of a smart contract, and the blockchain ensures that the contract cannot be tampered with ring the performance. In this way, there is no need to worry about safe space
it has strong expansibility, reasonable and legal
blockchain equity crowdfunding is composed of three-tier structure, and the bottom layer is blockchain network, which constructs a decentralized trust distributed system; The middle layer is the combination of business logic and blockchain to jointly establish account center, equity registration, equity voucher, equity transaction, equity management and other functions; The top layer is the crowdfunding platform for customer-oriented business, and the business of the platform can be extended to various fields and instries in theory
with techshares' blockchain technology, decentralized trust can be realized by building P2P self-organizing network, orderly and tamperable cryptography account book and distributed consensus mechanism. In addition, no matter the company law, the regulations on the administration of company registration or other laws and regulations, there are no specific restrictions on the form of expression of the register of shareholders maintained by the company itself. The company can choose to create and maintain the register of shareholders in any form with written records, not limited to specific carriers. Therefore, it is entirely reasonable and legal to use techshares as a carrier for equity crowdfunding on the blockchain. Once it is voluntarily chosen by the company, it can provide legal and effective proof for the company's equity (shares).

3. In the blockchain equity management chain system developed by Yingtang Zhongchuang, this system can realize the registration, transfer and OTC trading of equity on the blockchain. Based on the application scenario of VC, the blockchain equity management chain selects and matches the blockchain consensus algorithm and system security level. It has high flexibility and scalability, and can be used in other equity management or similar functions in the future

4. For this problem, we can simply use blockchain + big data to illustrate. For example, jinwowo group has started the research on big data with blockchain as the underlying technology. Because blockchain technology is also a distributed accounting mode, everyone in the system can have the opportunity to participate in accounting.

5. Build equity trading platform through blockchain technology, record static information such as enterprise equity and options, as well as dynamic information changing in the process of enterprise development in the blockchain distributed ledger, improve the efficiency of e diligence of investors, and match the transaction between equity transferor and investor.

What is blockchain finance

blockchain finance is actually the application of blockchain technology in the financial field. Blockchain is a kind of underlying technology based on bitcoin, and its essence is actually a decentralized trust mechanism. By sharing in distributed nodes, we can collectively maintain a sustainable growing database and achieve the security and accuracy of information. It is also a new technology system formed by integrating the existing technologies such as distributed storage, asymmetric encryption algorithm and timestamp, and introcing the consensus mechanism of algorithmic game theory

there are still many problems to be solved in order to achieve the goal of decentralization of blockchain. The traditional supply chain finance is a centralized mode. Basically, financial institutions and factoring companies rely on a core enterprise to provide services for about 80% of the SMEs in the supply chain. However, in the process of supply chain operation, logistics information, transaction information, capital information and information flow information are scattered within their own enterprises, and the information is not transparent, so financial institutions can not fully understand the enterprise credit, so it is difficult to avoid the phenomenon of reluctant to lend

first of all, relying on technology to greatly decentralize will proce new problems, and technical decentralization is not equal to market management decentralization. Whether the application of blockchain in the financial field can fully respect and protect the rights and interests of consumers still needs to be guaranteed by the regulatory authorities

financial enterprises have begun to use blockchain technology for self strengthening. For example, commercial banks can use blockchain technology to better manage points and collateral, better solve the problems of identity authentication and anti money laundering in the development of Internet finance, and promote the upgrading of Internet finance

in addition, by using blockchain and supporting technologies, commercial banks can better provide intelligent investment advisory and cash management services, and move towards the direction of transaction banks. In the future, Huixin cloud software collaborative service platform, the proct managers of the platform with the spirit of research, will conct in-depth research on the application scenarios of the blockchain. The scenarios will become increasingly rich, and the pace of technological innovation and mode innovation will be accelerated. With the application scope accelerating from financial to non-financial fields, the blockchain will graally become an important part of the future Internet, To lay an important foundation for building a value network

the above content comes from the interception part of the network library: blockchain financial system solution

hope to adopt, and you can refer to the network library: blockchain financial system solution if you don't understand

7. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system.

9. Regulatory variables can be qualitative or quantitative. In the analysis of regulatory effect, the independent variable and regulatory variable should be transformed centrally. Brief model: y = ax + BM + CXM + E. The relationship between Y and X is characterized by regression coefficient a + cm, which is a linear function of M, and C measures the size of the moderating effect. If C is significant, it means that the regulatory effect of M is significant. 2. Analysis method of regulatory effect analysis method of significant variable: divided into four cases. When the independent variable is a category variable and the moderating variable is also a category variable, the analysis of variance of two factor interaction effect is used, and the interaction effect is the moderating effect; When the regulatory variable is a continuous variable, the independent variable uses the pseudo variable, centralizes the independent variable and the regulatory variable, and does the hierarchical regression analysis of y = ax + BM + CXM + e: 1. Do the regression of y to X and m, and get the determination coefficient R1 2. 2. The regression of y to x, m and XM yielded R2 2. If R2 2 was significantly higher than R1 2, the regulatory effect was significant. Or, XM regression coefficient test, if significant, the regulatory effect is significant; When the independent variable is a continuous variable, the regulating variable is a category variable, grouping regression: grouping according to the value of M, doing y to x regression. If the difference of regression coefficient is significant, the regulation effect is significant. When the regulation variable is a continuous variable, the hierarchical regression analysis of y = ax + BM + CXM + e is done as above. There are two ways to analyze the moderating effect of latent variables: one is that the moderating variable is the category variable and the independent variable is the latent variable; The second is that both regulatory variables and independent variables are latent variables. When the moderator is a class variable, group structural equation analysis is performed. The method is to limit the regression coefficients of the two groups of structural equations to be equal, and get one χ 2 and the corresponding degrees of freedom. Then remove this restriction, re estimate the model, and get another one χ 2 and the corresponding degrees of freedom. ahead χ 2 minus the following χ 2 get a new one χ 2, the degree of freedom is the difference between the two models. If χ If the test result is statistically significant, the moderating effect is significant; When regulatory variables and independent variables are latent variables, there are many different analysis methods. The most convenient one is the unconstrained model proposed by marsh, Wen and Hau. 3. The definition of intermediary variable is the influence of independent variable x on dependent variable y. if x influences y by influencing variable m, then M is called intermediary variable. Y=cX+e1, M=aX+ e2 , Y= c′X+bM+e3 Where C is the total effect of X on y, AB is the mediating effect through M, and C 'is the direct effect. When there is only one mediating variable, there is C = C ′ + AB between the effects, and the mediating effect is measured by C-C ′ = ab. 4. Mediating effect analysis method mediating effect is indirect effect, regardless of whether the variables involve latent variables, structural equation model can be used to analyze mediating effect. The first step is to test system C. if C is not significant and the correlation between Y and X is not significant, stop the mediating effect analysis, and if it is significant, proceed to the second step; The second step is to test a and B once. If they are all significant, then test C ′, C ′, and the mediating effect is significant. If C ′ is not significant, then the complete mediating effect is significant; If at least one of a and B is not significant, do Sobel test, significant mediating effect is significant, not significant mediating effect is not significant. The statistic of Sobel test is Z = ^ A ^ B / SAB, in which ^ A and ^ B are estimates of a and B respectively, SAB = ^ a2sb2 + b2sa2, SA and Sb are standard errors of ^ A and ^ B respectively. 5. Comparison between moderator and mediator moderator m moderator m research purpose when does x affect y or when does x have a greater impact? How does x affect the moderating effect, interaction effect, mediating effect of y-related concepts When the influence of X on y is considered, the influence of strong x on y is strong and stable. The typical model is y = am + BM + CXM + e, M = ax + E2, y = C ′ x + BM + E3. The position of m in the model is x, M is in front of Y, M can be in front of X, the function of m after X and before y affects the direction (positive or negative) and strength of the relationship between Y and X. x influences the relationship between Y, m and X, X and X through it The correlation between M and X, y can be significant or not (the latter is ideal) the correlation between M and X, y is significant effect regression coefficient C regression coefficient proct AB effect estimate ^ C ^ A ^ B effect test whether C is equal to zero, AB is equal to zero test strategy do hierarchical regression analysis, test the significance of partial regression coefficient C (t test); 6. SPSS operation method of mediating effect and moderating effect. First, descriptive statistics, including M SD and internal consistency reliability (a) are used. Second, all variables are correlated, including statistical variables and hypothetical x, y, y, Third, regression analysis To choose linear regression in regression, we should first centralize the independent variable and m, that is, subtract their respective mean. 1. Now, we input m (regulatory variable or intermediary variable), y dependent variable, and demographic variable related to any of the independent variable, dependent variable, and M regulatory variable into independent. 2. Then press next to input x independent variable (intermediary variable so far). 3 In order to do the adjustment variable analysis, it is necessary to input the opportunity of X and m in the next for further regression. The test mainly depends on whether f is significant
