Episode 250: What’s the Deal with Hash Functions?

In this week’s episode, Anna and Kobi Gurkan speak with Dmitry Khovratovich, researcher at the Ethereum Foundation, Dusk Network, and ABDK Consulting and JP Aumasson CSO at Taurus. This episode compares symmetric and asymmetric cryptography as well as a deep dive into hash functions. They explore what hash functions are used for, the process of developing and improving hash functions, and what it means for a hash function to be “zk friendly”.
