ecc, electric coin company, halo, recursive snarks, trusted setup, zcash, zero knowledge
In this episode, we catch up with Sean Bowe and Daira Hopwood from the Electric Coin Company (ECC) to chat about Halo, a recursive proof composition that doesn't require a trusted setup. We cover the efficiency techniques used in Halo such as "nested amortization", how the protocol was developed, what some of the key findings are, and how it fits in with the other recent SNARK-based protocols.

blockchain, cryptography, filecoin, stark, zcash, zcash bug, zero knowledge proofs, zksnark
In this week’s episode, we welcome Ariel Gabizon, previously an Electric Coin Company (Zcash) engineer and cryptographer working on zero knowledge constructions. Ariel has worked closely with many of the exciting projects and researchers pushing the boundaries on zero knowledge research. He is also the person who discovered the Zcash bug (along with Sean Bowe and Zooko). In this episode, we explore his journey into the space, what inspires him, and what exciting new paradigms he is exploring today!
