In this week’s episode, we welcome special guest Sean Bowe. Sean is an engineer at the Electric Coin Company and the author of the Sprout and Sapling Zcash trusted set ups and much of the underlying cryptography of the protocol. We had a chance to chat about his history, what got him into the topic, some of the joys & challenges to working with SNARKs, and what ideas are inspiring him.

We also covered the story of Zcash and the Powers of Tau trusted set up, MPCs, the story of the bug, SONICs, ZEXE, the BLS12-381 Elliptic Curve Construction
