Smart contract security is a brave, new, and sometimes terrible field. This presentation will take you through a storytelling history of some of the most famous vulnerabilities of these first few years (from the Dao hack, to the Parity wallet vulnerabilities and including less-well-known but very interesting events like the DDOS attacks from late 2016). We’ll explain the details of how these attacks work(ed), some of the idiosyncrasies of Ethereum, and through these examples some general principles of smart contract security.
Attendees will gain a general understanding of security concerns in the emerging Ethereum ecosystem, and the history and execution of common attacks. The material is aimed at technical listeners with a security background but little blockchain-specific experience. We hope to share the fun of hacking on an unstoppable global computer with actual money as a primitive!
