通过复杂网络方法建模和理解以太坊交易记录

Modeling and Understanding Ethereum Transaction Records via a Complex Network Approach

Dan Lin, Jiajing Wu, Qi Yuan, Zibin Zheng

摘要:

作为最大的支持智能合约的公共区块链平台,以太坊自2014年首次亮相以来积累了大量的用户交易记录。然而,对以太坊交易记录的分析到目前为止仍然相对未被探索。现有方法将交易记录建模为静态简单图,无法准确刻画边的时间性和多重性。在本文中,我们首先将以太坊交易记录建模为一个复杂的网络,并结合交易的时间和金额特征,然后设计了几种灵活的时间行走策略,用于这个大规模网络的基于随机行走的图表示。在真实以太坊数据上进行的时态链接预测实验表明,边的时态信息和多样性特征对于以太坊交易网络的准确建模和理解是必不可少的。

英文摘要:

As the largest public blockchain-based platform supporting smart contracts, Ethereum has accumulated a large number of user transaction records since its debut in 2014. Analysis of Ethereum transaction records, however, is still relatively unexplored till now. Modeling the transaction records as a static simple graph, existing methods are unable to accurately characterize the temporal and multiplex features of the edges. In this brief, we first model the Ethereum transaction records as a complex network by incorporating time and amount features of the transactions, and then design several flexible temporal walk strategies for random-walk based graph representation of this large-scale network. Experiments of temporal link prediction on real Ethereum data demonstrate that temporal information and multiplicity characteristic of edges are indispensable for accurate modeling and understanding of Ethereum transaction networks.
