With the growing popularity of bitcoin, blockchain technology, as its underlying technology, has gained more and more attention. The technical innovation brought by blockchain technology such as decentralization and strong trust mechanism coincides with the nature of finance, which brings a new variable to the development of Internet finance, promotes the innovation in financial products and accelerates the development of mixed operation. At the same time, however, China’s current legal system of Internet finance is impacted by digital finance, which presents difficulties such as weakening the main bodies of financial regulation, confusing the objects of financial regulation and making it more difficult to protect financial consumers. Therefore, in the application of digital finance technology such as blockchain technology, Internet finance laws need to change the path of institutional evolution to meet the regulatory requirements brought by new technologies. The reform and impact of blockchain technology are promoting the transformation of Internet financial regulation mode from separate institutional regulation to functional regulation, from institutional regulation to technological regulation, and from monocentric regulation to multicentric regulation, as well as the transformation of the financial consumer protection mechanism.

Background/Objectives: With the rapid development of Internet technology, more and more Internet users tend to store their data and information in the cloud, and the security of the existing cloud storage system has been criticized by people, which is not conducive to protecting the data and information security of users. Therefore, how to effectively guarantee the security of cloud user data becomes more and more important. Security cloud storage system is the key to solve this problem. Methods/Statistical analysis: A secure cloud storage system is implemented for the user’s cloud data security. Its main function is: in the user login phase, the strict user identity authentication method is adopted to control the user’s access rights and prevent illegal users from logging in. Firstly, the identify authentication scheme based on zero knowledge proof is proposed. Secondly, in the user data upload stage, the user data is split. Finally, the encryption algorithm based on elliptic curve is proposed to encrypt the user’s file splitting table. Findings: The experimental results show that, in the user identify authentication stage, compared with the traditional user authentication method, the security of user identify authentication can be greatly improved by using the identify authentication method based on zero-knowledge proof. Improvements/Applications: The secure cloud storage system based on ellipse encryption developed in this thesis can realize the security of user's data by encryption while considering the efficiency of data upload and download, and has a broad application prospect.

The prediction of the financial market has gradually attracted attention from investors. As an emerging market, digital currency has become an indispensable and essential part. The common analysis methods are mainly machine learning and its derivatives. The daily frequency data of Bitcoin prices are obtained in this paper from June 2018 to September 2020. The Hidden Markov Model (HMM) is used to predict Bitcoin prices. In the model, the input observation sequence of the model is selected, including closing price, trading volume, and hidden state. They are in line with the current mainstream market perception: bull market, stable, and bear market. The results show that the relative error of the short-term forecast is relatively low, 0.347%. Compared with traditional models and machine learning methods, the Hidden Markov Model can better identify the state of the digital currency market and predict the direction of price movements, which verifies its application feasibility in the financial market.

The traditional offline review model of grid projects has the problems of high cost, high risk and low efficiency, making the project review insecure and inefficient. What is worse, the review data of a grid project are generally stored in a central database, which is vulnerable to attacks and not highly trustable. To solve the problems, this paper proposes a ring signature trust model based on smart contract, an important blockchain technology, for project review. The blockchain technology was introduced to build an online review platform for grid projects, greatly saving human and financial resources. Then, the consensus efficiency was improved with a trust-based node consensus mechanism. Besides, the ring signature was integrated with smart contract to allow review experts to submit their results anonymously, ensuring the fairness and impartiality of grid project review. On this basis, an efficient review system was established for grid projects, and a secure review environment was created, so that the review results will not be tampered with. The case analysis proves that the proposed method can effectively solve the problems of traditional grid project review, making the review system more secure and efficient. The research findings provide decision and theoretical supports for grid project review.
