They discuss the evolution of Zcash’s technical roadmap over the past five years and how it has influenced the design of Tachyon. Sean then walks through the cryptographic ideas behind Tachyon, including its proving systems, new techniques for pruning nullifiers without disrupting other parts of the protocol, and how the upgrade aims to address Zcash’s remaining scalability bottlenecks. They also explore plans for Zcash governance, wallet UX, and the long-term outlook for privacy-focused zero-knowledge systems.
