Tackling Rounding Errors with Precision Analysis

Duration: 00:27:01

Speaker: Raoul Schaffranek

Type: Talk

Expertise: Intermediate

Event: Devcon 6

Date: Oct 2022

Rounding errors in smart contracts can lead to severe security vulnerabilities. In this talk, we'll motivate the importance of rigorous numerical analysis through real-world exploits, and review existing precision analysis techniques. We'll then argue for the development of automated error propagation analysis tools to overcome the tediousness of manual efforts.
