# `ark-srs`

Use Common/Structured Reference String (CRS/SRS) from existing ceremonies with ease with arkworks types.

**WARNING: This is work in progress, none of the code has been audited. The library is NOT ready for production.**

## Download SRS to local

- Aztec's ignition: `./scripts/download_transcripts_aztec.sh NUM` where `NUM` can be `0..19` (`NUM=2` means download transcript `0, 1, 2`)

  - 100.8 million BN254 G1 points in total, split up into 20 files, each transcript file contains ~5 million points (~307 MB in size)

  - 2 BN254 G2 points are in the first transcript file

  - **If you only need `degree<=1,048,584`**, you will be directly using one of cached binary files in [Released Assets](https://github.com/alxiong/ark-srs/releases) (auto-downloaded when you run `setup()`).

## Usage

Our convention for module organization for different SRS is: `::::setup()`.

Here's an example of using Aztec's SRS for KZG over BN254 curve:

```rust

use ark_bn254::Bn254;

use ark_poly::univariate::DenseUVPolynomial;

use ark_srs;

// simulated CRS (for test only)

let pp = KZG10::::Fr>>::setup(max_degree, false, &mut rng)?;

// now, use Aztec's CRS

let pp = ark_srs::kzg10::aztec20::setup(supported_degree)?;

```
