An Effective Big Data Sharing Prototype Based on Ethereum Blockchain

Abstract

Because of its many advantages, big data has been extending to various domains of science, health, education, and commerce. Despite its many applications, big data sharing typically suffers from some key issues, such as user control, lack of incentives, cost, and the right of data. This paper proposes a decentralized big data sharing prototype to improve the applications and services of big data. The method makes use of Ethereum blockchain and related technologies to systematically recommend the implementation guidelines. The research provides a detailed description of the design and implementation of each sublayer of a big data system. As the method is based on blockchain technology, the key technical points are properly addressed in each of the layers. For evaluation, relevant data were collected, and functional testing was performed. A comparison was performed about the sharing frequency and blockchain consensus performance of similar platforms. The dual mining node of the proposed prototype succeeded in processing 1366 blocks and 300 messages. A comparatively satisfactory file access time in the range of 10 m to 20 s and file transmission time between 100 m and 200 s were achieved. The results obtained show that this prototype can effectively verify the feasibility of the model, the layered architecture, and the related sharing mechanism. For the functional and performance testing, practical projects were implemented and evaluated. The promising results obtained testify that the research offers a theoretical background for innovative research in the domain and specialized guidelines for practical implementation.

Blockchain-Assisted Hierarchical Attribute-Based Encryption Scheme for Secure Information Sharing in Industrial Internet of Things

“…As seen in Fig. 10, our scheme has a greater request approval rate than the existing work [57]. Our decentralized system still produces the best results despite the fact that the probability decreases as the number of requests rises due to the longer wait time.…”

EGQCY: A smart contract-based scientific big data system approach for incentive sharing and transaction on the cost of data quality

“…(5) Representative platforms include the National Science Foundation (NSF) physiological data sharing platform PhysioNet, the web-based survey data platform Digital Coast, Dartmouth University's wireless data sharing platform Crawdad, the US National data.gov, the National Earth System Science Sharing Service Platform of the Chinese Academy of Sciences, and others. The data from these platforms are interdisciplinary, large in volume, and significantly impact other related fields and platforms [25]. Medical information sharing, closely related to scientific research data, is similarly faced with the need to ensure the accuracy and integrity of medical information throughout the sharing process.…”

Blockchain-Based Privacy-Preserving Sensor Data Sharing with Fine-Grained Authorization in Microgrid

“…However, the scheme requires further optimization and improvement for multiple groups data. Based on the Ethereum blockchain technology, Song et al [22] accomplished the decentralization of the big data sharing system. However, these schemes mainly address data security and privacy issues and fail to focus on improving fairness in data sharing.…”
