“…Denial of service (DoS) attack is a method used to disrupt legitimate users' access to the target network or website resources [33][34][35]. Usually this is achieved by overloading a target with a large amount of traffic (usually a web server), or by sending malicious requests that cause the target resource to malfunction or completely collapse [36][37][38][39][40][41].…”

Distributed storage can store data in multiple devices or servers to improve data security. However, in today's explosive growth of network data, traditional distributed storage scheme is faced with some severe challenges such as insufficient performance, data tampering, and data lose. A distributed storage scheme based on blockchain has been proposed to improve security and efficiency of traditional distributed storage. Under this scheme, the following improvements have been made in this paper. This paper first analyzes the problems faced by distributed storage. Then proposed to build a new distributed storage blockchain scheme with sharding blockchain. The proposed scheme realizes the partitioning of the network and nodes by means of blockchain sharding technology, which can improve the efficiency of data verification between nodes. In addition, this paper uses polynomial commitment to construct a new verifiable secret share scheme called PolyVSS. This new scheme is one of the foundations for building our improved distributed storage blockchain scheme. Compared with the previous scheme, our new scheme does not require a trusted third party and has some new features such as homomorphic and batch opening. The security of VSS can be further improved. Experimental comparisons show that the proposed scheme significantly reduces storage and communication costs.

“…Scholars around the world have made some attempts, such as input-output model [1][2][3], system dynamics model [4][5][6], Kuznets curve [7][8][9][10][11], ridge regression model [12][13][14][15], Vertical Auto-regression model [16][17][18][19], and computable general equilibrium assessment [20][21][22][23][24][25]. One of the most widely used methods is the Kuznets curve, which reflects the inverted U-shape between economy and environment.…”

With the rapid development of the economy, China's environment has been damaged severely, which has attracted much attention from scholars and the local government. The concept of green development has been an underlying trend since 2012, and it is of great significance to explore the relationship between economic growth and environmental quality. Huzhou is a prefecture-level city under the jurisdiction of Zhejiang Province, and it is one of the 27 cities in the central area of the Yangtze River Delta. In recent years, this city develops well not only in economic development but also in maintaining a green environment. In the paper, the back propagation neural network is used to evaluate the local environmental quality. Meanwhile, the panel model is exploited to analyze the relationship between economic growth and environmental quality. All the data presented in the paper range from the year 2008 to 2018. Theoretical analysis indicates that the evaluation value of environmental quality, the emissions of industrial SO 2 , and waste water exhibit an inverted U-shaped relationship with economic growth. As for the regression results, the inflection point of income in the environmental Kuznets curve of the model which takes the evaluation value of the environmental quality as a dependent variable is higher than that of the model which takes the SO 2 emission as an independent variable. The research result would help the local government to take appropriate countermeasures to improve the environment and economy.

“…Wang et al [34] proposed a data integrity scheme for cloud-IoT data by blockchain and bilinear mapping, which introduced provable update mechanism to support dynamic IoT data. Wang et al [35,36] proposed concrete private blockchain-based schemes which also realized client's privacy preserving. To address the centralized problem of TPA, Dong et al [37] presented a secure data integrity checking scheme based on consortium blockchain, which also designed a punishment mechanism to punish the TPA who failed to send the audit result in time.…”
