In this episode, we catch up with Sean Bowe and Daira Hopwood from the Electric Coin Company 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.   We touch on the following material:  Sean Bowe on SNARKs, Trusted Setups &amp; Elliptic Curve Cryptography https://github.com/daira/tweedle Halo whitepaper Endomorphism Latest recursive SNARKitecture with Izaak Meckler from O(1)Labs Exploring the Fractal transparent SNARK construction  If you like what we do:  Follow us on Twitter - @zeroknowledgefm Join us on Telegram Support our Gitcoin Grant Support us on the ZKPatreon Or directly here:  ETH: 0xC0FFEE1B5083230a5154F55f253B6b6ae8F29B1a BTC: 1cafekGa3podM4fBxPSQc6RCEXQNTK8Zz ZEC: t1R2bujRF3Hzte9ALHpMJvY8t5kb9ut9SpQ

Episode 123: Halo with Sean Bowe and Daira Hopwood from ECC

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 &amp; 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 Early on in the episode, we mention the Radiolab episode about the zcash trusted setup: https://archive.org/details/radiolab_podcast17crypto_zcash_ceremony Questions from the audience: https://twitter.com/AnnaRRose/status/1122818062061797376 We also mention some of our previous ZK centric episodes that can be found here: https://www.zeroknowledge.fm/zkseries  Special thanks to this week's sponsor: Trail of Bits  Trail of Bits is offering a service for young technology companies who could use expert security support, but aren't quite at a stage to hire their own team.

Episode 76: Sean Bowe on SNARKs, Trusted Setups & Elliptic Curve Cryptography

Zcash is a payment and consensus system that allows users to transfer money to each other with strong guarantees of privacy. Zcash implements the same core features of Bitcoin, with the added functionality of shielded payments. Shielded payments are private, and they are enabled by a novel cryptographic technique called zk-SNARKS: zero knowledge succinct non-interactive argument of knowledge. A zk-SNARK allows for the proof that a certain piece of information is valid without revealing any information other than the validity of that information itself. Before you listen to this episode, it might be useful to go back to our previous episode about Zcash with Nathan Wilcox, in which he gives an overview of the technology. This episode is a deeper dive into how Zcash transactions work, and why zk-SNARKS are important. We would love for you to fill out our listener survey at softwareengineeringdaily.com/survey. This will help us decide what other content to focus on. Of course–you can also send me an email at any time, jeff@softwaredaily.com. And in the meantime, if you are completely sick of cryptocurrencies, check out our back catalog of episodes at softwaredaily.com, or by downloading our apps, which have all of our episodes including our Greatest Hits, which is a curated set of the most popular shows. The apps will soon have offline downloads and bookmarking. The post Zcash Design with Sean Bowe appeared first on Software Engineering Daily.
