This repository contains several Rust crates that implement the different building blocks of ZEXE. The high-level structure of the repository is as follows.
* [`algebra`](algebra): Rust crate that provides finite fields and elliptic curves
* [`algebra-core`](algebra-core): Rust crate that provides generic arithmetic for finite fields and elliptic curves
* [`algebra`](algebra): Rust crate that provides concrete instantiations of some finite fields and elliptic curves
* [`crypto-primitives`](crypto-primitives): Rust crate that implements some useful cryptographic primitives (and constraints for them)
* [`dpc`](dpc): Rust crate that implements DPC schemes (the main cryptographic primitive in this repository)
* [`ff-fft`](ff-fft): Rust crate that provides efficient finite field polynomial arithmetic based on finite field FFTs

Compiling with `adcxq`, `adoxq` and `mulxq` instructions can lead to a 30-70% speedup. These are available on most `x86_64` platforms (Broadwell onwards for Intel and Ryzen onwards for AMD). Run the following command:
```bash
RUSTFLAGS="-C target-feature=+bmi2,+adx" cargo +nightly test/build/bench --features asm
```
Tip: If optimising for performance, your mileage may vary with passing `--emit=asm` to `RUSTFLAGS`.
To bench `algebra-benches` with greater accuracy, especially for functions with execution times on the order of nanoseconds, use the `n_fold` feature to run selected functions 1000x per iteration. To run with multiple features, make sure to double quote the features.
```bash
cargo +nightly bench --features "n_fold bls12_381"
```
