# sapling-mpc

This code can be used to participate and verify the Sapling network upgrade MPC.

## What do I do?

Contact **mpc@z.cash** to schedule a time to participate. You'll need the latest (stable) [Rust compiler](https://www.rust-lang.org/) to participate using this code.

When it's your turn, you'll receive a `params` file from us. Place this file in the current directory and run:

```
cargo run --release --bin compute
```

This will compute for a little while, and then spit out a `new_params` file. That's what you'll upload back to us.

The tool also prints a hash. This hash is what you and others can use to verify that your contribution actually ended up in the final parameters, so you're encouraged to save it to check later!
