Abstract

The inherent distributed and anonymity features of the blockchain system may cause illegal activities like improper content dissemination, illegal transactions, money laundering, etc., posing a severe threat to the blockchain. Due to the ultra-large scale of the public chain system, identifying key nodes in the transaction network is usually cost-intensive and time-consuming. In this paper, we propose a transaction graph-based scheme to identify key nodes in the public blockchain, where a multi-stage key node detection algorithm is proposed. Real Ethereum transaction data validates the performance of the proposed scheme. It is shown that with a data volume of millions of items, our multi-stage approach can effectively eliminate low-value information from the data and realize high-efficiency key node detection, with similar performance compared to traditional algorithms without filtering, and an extremely large improvement in algorithm execution time.

基于交易图的区块链监管关键节点识别

区块链系统与生俱来的分布式和匿名性特点，可能会导致不当内容传播、非法交易、洗钱等非法活动，对区块链构成严重威胁。由于公有链系统的超大规模，识别交易网络中的关键节点通常需要耗费大量的成本和时间。本文提出了一种基于交易图的公有区块链关键节点识别方案，其中提出了一种多阶段关键节点检测算法。真实的以太坊交易数据验证了所提方案的性能。结果表明，在数据量达数百万条的情况下，我们的多阶段方法可以有效剔除数据中的低价值信息，实现高效率的关键节点检测，其性能与不带过滤功能的传统算法相近，并且算法执行时间有了极大的改善。

期刊介绍： The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security. The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain. Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
