Alan Szepieniec on Hash Functions & Supersonic SNARKs

In this week’s episode, we catchup with Alan Szepieniec, a researchers at Nervos and co-author of the https://eprint.iacr.org/2019/1229.pdf (Supersonics) paper and https://eprint.iacr.org/2019/426.pdf (the Marvellous family of Hash Functions) (which specify the Vision/Rescue cyphers). We chat about his past work in cryptography, how the Supersonics paper came to be, and dive into the new generation of hash functions emerging, including the Marvelous universe.
