Zoltán Balázs - Ethereum Smart Contract Hacking Explained like I’m Five

Mining. Ethereum. Smart Contracts. Gas. Solidity. DAO. These words had no or a different meaning 5 years ago. But now these are the foundations of something exciting and powerful. But with great power comes great responsibility. Designing and implementing Smart Contracts are like encryption protocols. Everyone can come up with one which looks secure from the developer’s perspective, but only a few can design and implement one which is really safe. But how can one hack Smart Contracts? In order to understand this, I will explain the meaning of all of these words in the Ethereum world from the ground-ups with real life analogies. Once the basic building blocks are explained, I will guide you into the world of hacking Smart Contracts. After attending this presentation, everyone will understand how a recursive call can burn 250M USD on the DAO and how developers can create a parallel universe where this never happened. Reinit? Multi-signature wallets? The Parity hack? All of this is simple once the basics are founded. Warning: case studies from recent real-life hacks and live interaction with Smart Contracts are included. And Cryptokitties. Meow. https://www.hacktivity.com
