Sam Bowne - Securing Smart Contracts

Learn how blockchains, cryptocurrency, NFTs, and smart contracts work, and their most important security flaws. We will also cover the underlying cryptography: hashes, symmetric encryption, and asymmetric encryption. We will configure wallets, servers, and vulnerable smart contracts, and exploit them.

We will configure systems using Bitcoin, Ethereum, Hyperledger, Multichain, Stellar, and more. We will perform exploits including double-spend, reentrancy, integer underflow, and logic flaws.

No previous experience with coding or blockchains is required.

This workshop is structured as a CTF competition, to make it useful to students at all levels. We will demonstrate the easier challenges from each topic, and detailed step-by-step instructions are available. We will have several instructors available to answer questions and help participants individually. Every participant should learn new, useful techniques.

Pre-requisites:

• Beginners are welcome. Familiarity with cryptocurrency and smart contracts is helpful but not necessary.

Materials or Equipment Required:

• Any computer with a Web browser. The capacity to run a local virtual
• machine is helpful but not required.
