# phase2 [![Crates.io](https://img.shields.io/crates/v/phase2.svg)](https://crates.io/crates/phase2) #

Forked from [kobigurk/phase2-bn254](https://github.com/kobigurk/phase2-bn254).

This library is still under development.

## WebAssembly how-to

Build wasm package using `wasm-pack build --release -- --no-default-features --features wasm`

this will generate `./pkg` directory with wasm file and js bindings. After that you 
can use this package in your browser application like so:

```js
async function main() {
    const phase2 = await import("./pkg/phase2.js")
    let data = await fetch('params')
    data = await data.arrayBuffer()
    data = new Uint8Array(data)
    console.log('Source params', data)
    const result = phase2.contribute(data)
    console.log('Updated params', result)
    // upload updated params
}

main().catch(console.error)
```
