Contribute to the ceremony

Prerequisites

You will need Rust to compile the code that generates your contribution. You can follow the recommended guide. Recommended Rust version is nightly-2023-05-22.

Compute your contribution

First, clone the following code:

git clone https://github.com/dusk-network/powersoftau.git

Once you get contacted by the coordinator, you will be provided with a challenge file named challenge. Place the file in the root of the cloned repository, navigate to the repository, and execute:

cargo run --release --bin compute

When executing the previous command, you will be asked for entropy. It is important that you introduce a large and completely random input for optimal security. Some examples of entropy sources are:

  • Randomly typing on your keyboard with the eyes closed.
  • Take random words from random pages in random books or magazines you have at home.
  • Generate various values using /dev/urandom in different devices.

Such input must not be copied or stored anywhere.

It will take some time to compute a response file containing your contribution. Once finished, you will need to submit your contribution.

Submit your contribution

To submit your contribution, provide the following to the coordinator:

  • The generated response file.
  • A report file containing the following information:
    • Brief description of the device used.
    • The time taken to compute the contribution.
    • The hash of the challenge you used.
    • The hash of the response file.
    • Brief description of the entropy source you used and any precautions you took to ensure that it's not possible to recover the value you introduced.
  • One of the following ways to verify your identity:
    • A signature of the report file, and the link to a public profile containing the public key (e.g. the GPG key in your GitHub account).
    • A link to a post on a social network where you publicly published your report.
