Blockchain Security: Pwning the "Silver Bullet"
Blockchain (and Cryptocurrency) is an evolution of 20-year old research from scientists like Chaum, Lamport, and Castro & Liskov. Due to the current hype, it's hard to distinguish beneficial aspects of the 
technology from a desire for a "silver bullet" for device security, verifiable logistics, or "saving democracy". The problem: blockchain introduces new security challenges - and blind adoption without understanding reduces overall security. In this talk, Melanie Rieback and Klaus Kursawe explain the pitfalls and limits of blockchain, so you can avoid making your applications LESS secure.
