A Comprehensive Survey on Blockchain Data Privacy and Security

·

In a significant academic achievement, a research team led by Professor Liang Wei from the School of Computer Science and Engineering has published a comprehensive survey paper in the prestigious international journal, ACM Computing Surveys (CSUR). The paper, titled “On Identity, Transaction, and Smart Contract Privacy on Permissioned and Permissionless Blockchain: A Comprehensive Survey,” represents a thorough investigation into privacy and security challenges within blockchain systems.

ACM Computing Surveys is a highly respected journal published by the Association for Computing Machinery (ACM). Established in 1969, it is dedicated to publishing high-quality survey articles that represent significant advancements in the field of computing. It is ranked in the SCI Zone 1 by the Chinese Academy of Sciences and boasts an impressive latest impact factor of 23.8. Currently, it holds the top position as the highest-ranked international journal in computer science based on CiteScore.

This survey paper provides a panoramic overview of data privacy and security protection within blockchain technology. It examines the latest architectures, solutions, and research achievements in blockchain privacy protection, offering valuable insights for both practitioners and researchers.

Key Findings and Research Focus

The study begins by detailing the privacy and security risks associated with the public storage of smart contract and transaction data. These risks stem from the inherent characteristics of blockchain, such as decentralization, immutability, and traceability. The paper highlights the impacts and challenges that arise when user information on the blockchain is leaked.

A considerable portion of existing research has concentrated on permissionless blockchains or cryptocurrencies. However, privacy protection technologies for consortium blockchains (also known as permissioned blockchains) require more in-depth exploration. This survey addresses that gap by comprehensively reviewing the latest research methods concerning identity, transaction, and smart contract privacy.

The paper also summarizes various issues, threats, and challenges related to data security regulation across different blockchain architectures. It aims to propose several open questions to inspire further thinking and investigation within the academic community.

Finally, the research explores future directions for privacy protection technologies in consortium blockchains. It provides feasible research ideas to promote the rapid development and adoption of these technologies.

Significance and Impact

This work offers substantial reference value for advancing the healthy and rapid development of blockchain data privacy and security protection technologies. It serves as a crucial resource for understanding current landscapes and future possibilities in the field.
