论文摘要
分散的金融（DEFI）以其独特的机制设计而闻名，该设计适用于智能合约来促进点对点交易。分散的银行是典型的Fefi应用程序。理想情况下，分散的银行应在交易中分散。但是，许多最近的研究发现，分散的银行尚未实现大量的权力下放化。这项研究进行了主流分散银行的比较研究。我们使用来自四个分散银行，酒类，AAVE，MAKERDAO和化合物的交易数据应用核心外围网络特征分析。我们提取六个功能，并在横截面上比较银行的权力下放化水平。根据分析结果，我们发现：1）Makerdao和Compound在交易中比AAVE和酒类更分散。 2）尽管分散的银行交易应该是分散的，但数据表明，四家银行具有主要的外部交易核心地址，例如Huobi，Coinbase和Binance等。我们还讨论了可能影响网络分散化的四个设计功能。我们的研究为分散财务，金融技术（FINTECH）和社交网络分析的界面上的文献做出了贡献，并激发了未来的协议设计，以实现分散财务的承诺，以实现真正的点对点交易网络。
Decentralized finance (DeFi) is known for its unique mechanism design, which applies smart contracts to facilitate peer-to-peer transactions. The decentralized bank is a typical DeFi application. Ideally, a decentralized bank should be decentralized in the transaction. However, many recent studies have found that decentralized banks have not achieved a significant degree of decentralization. This research conducts a comparative study among mainstream decentralized banks. We apply core-periphery network features analysis using the transaction data from four decentralized banks, Liquity, Aave, MakerDao, and Compound. We extract six features and compare the banks' levels of decentralization cross-sectionally. According to the analysis results, we find that: 1) MakerDao and Compound are more decentralized in the transactions than Aave and Liquity. 2) Although decentralized banking transactions are supposed to be decentralized, the data show that four banks have primary external transaction core addresses such as Huobi, Coinbase, and Binance, etc. We also discuss four design features that might affect network decentralization. Our research contributes to the literature at the interface of decentralized finance, financial technology (Fintech), and social network analysis and inspires future protocol designs to live up to the promise of decentralized finance for a truly peer-to-peer transaction network.
