Episode notes
Orchard As Recursion Foundation
- Orchard used Halo 2-style proving without a trusted setup and set the stage for future recursion-based scaling.
- Tachyon will reuse Orchard's recursion-friendly cryptography for greater scale.
Avoid Long-Lived Trusted Setups
- Avoid relying on trusted setups for long-term protocol trust and upgrade flexibility.
- Prefer universal or setup-free SNARK approaches to reduce future trust and upgrade risks.
Prioritize UX To Grow Privacy Use
- Prioritize usability: invest in mobile UX, hardware wallet support, and unified addresses to grow private usage.
- Make wallets hide complexity so users rarely need to manually migrate pools or understand backend details.
