sapling-mpc

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

How do I verify the Sapling parameters?

Download these three files from the Powers of Tau ceremony and place them in your current directory:
- phase1radix2m13
- phase1radix2m17
- phase1radix2m21
Ensure you have downloaded the Sapling parameters. If you have Zcash installed on Debian or Ubuntu, you can run zcash-fetch-params to obtain them; otherwise, download the Zcash source code, and then run ./zcutil/fetch-params.sh to obtain them.

Run the following command:

cargo run --release --bin verify --features="verification"

How do I participate?

The Sapling ceremony is complete!

How did participation work?

Contact mpc@z.cash to schedule a time to participate. You'll need the latest (stable) Rust compiler 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!
