Provotum Mixnet

The project is structured into four different packages:

• node: The Provotum Mixnet implemented using Substrate
• crypto: A cryptographic library implementing all algorithms and proofs
• randomizer: A service to randomizes the voters ballots'
• client: A CLI to interact with the randomizer and the node

For more information have a look at the individual packages.

Demo Setup

Start Up

To start a multi-node local test network, the docker-compose.yml file can be used.

docker-compose up

This starts a three-node local test network with:

• Alice, as voting-authority (cannot author blocks, but is the voting admin)
• Bob and Charlie, as sealers and PoA-authorities (can author blocks)

Also, starts a randomizer service for ballot re-encryption:

• Randomizer

Interact

To interact with the test setup use the client CLI. Have a look at the README of the client package on how to build the CLI and use it.
