Halo2NU5 brings the third shielded pool, Orchard, to the Zcash protocol. Orchard is similar in a lot of ways to Sapling, but for some very important differences: the new Halo 2 recursive zk-SNARK proof system, based on new cyclic curves Pallas and Vesta; Actions instead of Spends or Outputs; and more. This session will lay out what Orchard brings to Zcash, how it differs from Sapling, and how Halo 2 removes the trusted setup for parameters and sets up Zcash for using recursive proofs in future upgrades. Speakers: Sean Bowe is a cryptographic engineer and researcher who has implemented, designed and discovered state-of-the-art cryptographic primitives and techniques, particularly focused on SNARKs and recursive proofs. His main focus is on building and improving Zcash's shielded protocol. Twitter @ebfull Daira Hopwood is an anarchist, cryptographer, ZIP editor, and the lead author of the Zcash Protocol Specification. Ze has been heavily involved in the design of the shielded protocols used in Zcash since before launch. Twitter @feministPLT Deirdre Connolly is a cryptographic engineer and the senior engineer on Zebra, working at the Zcash Foundation since spring 2019. When not trying to deploy secure, resilient, and respectful cryptographic systems, she is keeping one eye on the quantum-safe cryptosystems of the future.

We've already initiated a policy for Sprout that limits transfers into the Sprout pool, but we need a more general set of guidelines for how we might retire older pools and technologies so that we can move faster with our engineering efforts and reduce protocol complexity. This session presents some of Nate's (and Steven's, who, due to unforeseen circumstances could not attend Zcon3) thoughts on how this could be accomplished, including a discussion of the social aspects of pool retirement. Speaker: - Nate Wilcox is the Chief Research Officer at Electric Coin Company (ECC) where he has been helping coordinate world class developers on ongoing Zcash breakthroughs. He came to ECC from Least Authority where he coordinated open source security audits.

This is one approach to a hybrid PoW + PoS protocol aimed at being a safe first step transition from the current PoW protocol towards PoS. The design is incomplete, and the workshop begins with an overview of the motivations, goals, existing portions of design, and known open questions / unresolved areas. As a group, we will spend a portion of time brainstorming alternative approaches, then dig into either existing parts of the design or open areas to brainstorm next steps and approaches. Notes from the meeting will be shared to the public after Zcon4 to solicit further progress and collaboration.

Kurt discusses the broader civil liberties context, not just privacy, but free expression (code is speech), due process for government inquiries, and the value of anonymity in effectuating those rights. He also talks about how the Zcash community can help protect these rights, with lessons from his work in digital rights advocacy, by learning the issues, building grassroots support and having their voices heard.

We will go through a brief history of financial surveillance, covering defining moments that shape our relationship with Big Brother today (e.g. 9/11). Then, we look forward, plotting a path from today to the futures depicted in fictional dystopias. We focus on the country of Gilead in Margaret Atwood's Handmaid's Tale [author's note: they may add other references]. How did women so entirely lose control of their lives? What tools of surveillance were employed, and how did women eventually lose their financial autonomy? Michelle Lai is builder and investor in crypto. She is also a strong privacy advocate, believing that crypto/blockchain are essential tools for free societies in our technocractic future. She has worked with Anchorage, Bitpay, and Copper, served on the first Zcash grant committee, and is involved with the Universal Privacy Alliance. Prior to tech, she worked in investments in financial institutions - where, through the Global Financial Crisis in 2008, she realized ""trustless"" is better than ""trusted.""

Halo2: #Zcon2LiteNU5 brings the third shielded pool, Orchard, to the Zcash protocol. Orchard is similar in a lot of ways to Sapling, but for some very important differences: the new Halo 2 recursive zk-SNARK proof system, based on new cyclic curves Pallas and Vesta; Actions instead of Spends or Outputs; and more. This session will lay out what Orchard brings to Zcash, how it differs from Sapling, and how Halo 2 removes the trusted setup for parameters and sets up Zcash for using recursive proofs in future upgrades. Speakers: - Sean Bowe is a cryptographic engineer and researcher who has implemented, designed and discovered state-of-the-art cryptographic primitives and techniques, particularly focused on SNARKs and recursive proofs. His main focus is on building and improving Zcash's shielded protocol. Twitter @ebfull - Daira Hopwood is an anarchist, cryptographer, ZIP editor, and the lead author of the Zcash Protocol Specification. Ze has been heavily involved in the design of the shielded protocols used in Zcash since before launch. Twitter @feministPLT - Deirdre Connolly is a cryptographic engineer and the senior engineer on Zebra, working at the Zcash Foundation since spring 2019. When not trying to deploy secure, resilient, and respectful cryptographic systems, she is keeping one eye on the quantum-safe cryptosystems of the future.
