plonky2 is largely focused on recursion performance. We use custom gates to mitigate the bottlenecks of FRI verification, such as hashing and interpolation. We also encode witness data in a ~64 bit field, so field operations take just a few cycles. We use an extension field to boost soundness when needed.

Running

To run the recursion benchmark,

RUSTFLAGS=-Ctarget-cpu=native cargo run --release
