It is our great pleasure to welcome you to the 2021 ACM Workshop on Decentralized Finance and Security - DeFi 2021. The purpose of this workshop is to unite researchers with deep knowledge in the many subfields of DeFi (network, consensus, game theory, programming language, economics and security), to jointly revisit their security and privacy properties. The mission of the DeFi workshop is to elaborate on how we can protect DeFi users from malicious trading entities and what kind of attacks those could mount.
The call for papers attracted 11 submissions from Asia, Europe, and the United States. The program committee reviewed and accepted four outstanding papers (36%).
