Panoramix Framework and Tools

This repository includes the Panoramix Mixnet Service and the Panoramix Trust Control Panel.

Panoramix Mixnet Service

This is a framework that enables setting up and running mixnets. It employs three python packages:

  • panoramix: The main package that implements the mixnet logic
  • panoramix-service: A server implementing the panoramix API
  • panoramix-agent: A local agent for posting messages


In each of the three packages, run:

python install

The panoramix package includes three cryptographic backends: 'gpg', 'zeus', and 'sphinxmix'. In order to use them, you must install the respective dependencies with:

pip install -r requirements_.txt


The service can be run with panoramix-manage runserver --nothreading.

The panoramix package provides a wizard (panoramix-wizard) to allow the mixnet contributors to set up a mixnet (currently works with the sphinxmix backend only).

The panoramix-agent package provides a local agent to enable an end user to use a mixnet. As an example, sphinxmix-agent is a wizard to configure and launch an agent for sphinxmix. The end user can send messages to the mixnet by posting it to the local agent, using the panoramix-client.


Check file EXAMPLE for an extended description on how to setup and use a sphinxmix mixnet. For a demonstration of Panoramix workflow, see demo/README.

Panoramix Trust Control Panel

This is a tool that provides a cryprographically secure and auditable mechanism for configuring applications jointly by multiple mutually untrusted authorities.


The Trust Control Panel employs three python packages:

  • consensus-service: A server the runs negotiations among users
  • consensus-client: Client for the consensus service
  • trustpanel: The Trust Control Panel base logic

and an Ember-based web interface.

Each application that wishes to employ this tool must extend the trustpanel base package. As an example, the repository includes an extension for the Zeus E-voting System (directory zeus_trust):

  • - Initialize and launche the trust panel.
  • - Configure the user actions for each configuration option.
  • - Specify the configuration options.


The tool can be deployed using docker. From the root directory, run:


By default, the Zeus extension is installed and run. The Trust Control Panel is accessible at http://localhost:9000/ui/trustee1/.

Extensions for other applications must be registered in the file docker/services.conf.
