Title: The Overlooked Role of Communication Networks in Blockchain Design
Speaker: Giulia Fanti
Date and Time: 5/12/2022 4:10PM ET
Location: Phillips 233 and Zoom
Abstract: Blockchains have become an important tool for maintaining distributed ledgers among mutually untrusting parties. As the systems that use these ledgers (e.g., cryptocurrencies) grow in popularity, it is becoming increasingly important to ensure their robustness along multiple axes, such as performance, security, privacy, and fairness. To date, most of the literature on these topics has tackled them at the application layer. In this talk, we will instead discuss the role that communication networks play in designing robust blockchain systems. We will illustrate this point through two case studies focusing on privacy and fairness. In these case studies, we highlight how careful modeling, analysis, and design of underlying communication networks can have implications at other layers. These design and analysis challenges introduce new problem formulations combining elements of graph algorithms, random processes, and distributed systems.
