The program operates as a retroactive grants program, and allows **ZEC holders to vote** on completed projects they believe delivered meaningful value to the Zcash ecosystem. A proposal is approved only if at least 420,000 ZEC participate in its vote.

Despite this challenge, the ECC wallet team has made relentless efforts to foster a stronger community around Zcash. As a result, we have received more contributions in the last few months than in the last few years, combined! This session covers the lessons learned along the way. First, we will contrast what has failed against what has worked. Then, we will conclude by outlining our ideas around incentive plans and developer appreciation, going forward.

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.

We've had several successful network upgrades and learned a lot about the NUP and ways it could be improved especially when coordinating across additional node and protocol development teams. This session will review the rationale for the NUP and provide an overview of how it's evolved over the years. We'll then explore ways we can further improve the NUP and make it work for multiple development teams while preserving the same standards and controls that have produced several successful network upgrades in the past.

If we are to believe that these technical solutions are reliable, we are relying on the cryptography they utilize. Audits of both the types and implementations of cryptography by industry professionals are critical to advancing these solutions. We'll discuss what it means to audit cryptography, how best to approach it and what we see as the future of cryptography audits.
