This week, Anna and Guillermo chat with David Wong, author of the Real-World Cryptography book, and a cofounder [zksecurity.xyz]((https://www.zksecurity.xyz/) - an auditing firm focused on Zero Knowledge technology.

They chat about what first got him interested in cryptography, his early work as a security consultant, his work on the Facebook crypto project and the Mina project, zksecurity.xyz, auditing techniques and their efficacy in a ZK context, what common bugs are found in ZK code, and much more.
