Ethereum, a blockchain, supports its own cryptocurrency named Ether and smart contracts. Although more than 8M smart contracts have been deployed on Ethereum, little is known about the characteristics of its users, smart contracts, and the relationships among them. We conduct the first systematic study on Ethereum by leveraging graph analysis to characterize three major activities on Ethereum, namely money transfer, smart contract creation, and smart contract invocation. We collect all transaction data, construct three graphs from the data to characterize major activities via graph analysis, and discover new insights. Moreover, we address three security issues based on graphs.

通过图分析了解以太坊

以太坊是一个区块链，它支持自己的名为 Ether 的加密货币和智能合约。尽管以太坊上已经部署了超过 800 万个智能合约，但对其用户特征、智能合约以及它们之间的关系知之甚少。我们进行第一的通过利用图形分析来描述以太坊上的三个主要活动，即资金转移、智能合约创建和智能合约调用，对以太坊进行系统研究。我们收集所有交易数据，从数据中构建三个图表，通过图表分析来描述主要活动，并发现新的见解。此外，我们基于图解决了三个安全问题。
