The Orchard Shielded Pool, feat. Halo2:
NU5 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. Twitter @durumcrustulum
