First, social networks generate and disseminate information, especially information that individuals and institutions are not obliged to disclose, which improves people's "integrity", greatly reduces the cost of financial transactions, and lays a foundation for financial transactions. effect. (The information revealing role of social networks can be expressed as: individuals and institutions have a large number of stakeholders in society. These stakeholders all have some information, such as property status, business conditions, consumption habits, reputation behavior, etc.

The information of a single stakeholder may be limited, but if these stakeholders all publish the information they have on social networks, they can get complete information on credit qualifications and profit prospects. For example, "Taobao." "Net" is similar to a social network. The massive information formed by transactions between merchants, especially the information on the exchange of goods and funds, shows the credit qualifications of merchants. If Taobao sets up a small loan company, it can use this information to issue small loans to some merchants. Loan, the effect will be very good. )

Second, the organization, sorting and retrieval of information by search engines can alleviate the problem of information overload and meet information needs in a targeted manner. The integration of search engines and social networks is a trend. The essence is to use the relationship data contained in social networks to filter information, which can improve the level of "integrity". For example, the "crawler" algorithm for crawling web pages and the link analysis method for ranking web pages (represented by Google's PageRank algorithm) both utilize the link relationships between web pages and are relational data.

Third, cloud computing ensures high-speed processing capabilities for massive information. Under the protection of cloud computing, information on both supply and demand sides of funds is revealed and disseminated through social networks, organized and standardized by search engines, and ultimately forms a time-continuous and dynamically changing information sequence. The risk pricing or dynamic default probability of any fund demander (institution) can be given at extremely low cost. In this way, the information basis (sufficiency condition) for financial transactions is satisfied. A spot trading market for computing power has already emerged in February 2011, and a futures market is expected to follow suit. The financial industry is a large user of computing power, and cloud computing will have a significant impact on the financial industry.
