Security of Decentralized Financial Technologies (Dagstuhl Seminar 22421)

The decentralized finance (DeFi) sector has grown to a 13+ billion USD economy, encompassing various financial activities. The non-custodial nature of DeFi requires users to take responsibility for managing their assets, but it also provides them more control over their assets. The Dagstuhl Seminar brought researchers together to examine the security, privacy, and financial properties of DeFi and explore ways to protect users. The seminar aimed to reconcile the conflicting demands of security, usability, and performance in DeFi and outline best practices. Despite progress made in the DeFi sector, there is still much to be explored and improved, such as user education, regulatory compliance, and the scalability and performance limitations of decentralized ledgers. To build a secure and user-friendly DeFi ecosystem, continued collaboration among experts is needed.
