Commit-Reveal Schemes Against Front-Running Attacks (Extended Abstract)

Authors: Andrea Canidio and Vincent Danos

Published in: OASIcs, Volume 110, 4th International Conference on Blockchain Economics, Security and Protocols (Tokenomics 2022)

Abstract
We provide a game-theoretic analysis of the problem of front-running attacks. We use it to study a simple commit-reveal protocol and discuss its properties. This protocol has costs because it requires two messages and imposes a delay. However, we show that it prevents the most severe front-running attacks ("bad MEV") while preserving legitimate competition between users, guaranteeing that the earliest transaction in a block belongs to the honest user who values it the most ("good MEV").

Security of Decentralized Financial Technologies (Dagstuhl Seminar 22421)

Authors: Arthur Gervais and Marie Vasek

Published in: Dagstuhl Reports, Volume 12, Issue 10 (2023)

Abstract
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.
