It takes 3 hours on a single 10-core machine, compared to previous version's 36 hours using nine 64-core machines. This speedup is due to the usage of the Plonky2 framework, which compiles Rust-coded circuits into efficient machine language instead of using slower Python scripts. We also enhanced Plonky2 to run some computations on GPUs, reducing the time by an extra 30%. Better auditability: With Version 2, we use a high-level framework that handles complex cryptographic details for us.
