The Path to Shielded Programmability with Ying Tong Lai and Bryan Gillespie - ZconV: Zcash Unified
In 2023, the Zcash Foundation issued a grant to Ying Tong Lai, Daniel Benarroch and Bryan Gillespie to conduct research leading to a systemization of knowledge (SoK) of the options for adding privacy-preserving programmability to Zcash. During Zcon4, Ying Tong and Daniel provided an update on the progress of this research. During this session, Ying Tong and Bryan will present an overview of their research results, and outline some potential paths forward for the Zcash community.
