Dscuss is a free software for public discussion. It builds an unstructured pure P2P topic-based publish-subscribe network. Currently it's in early development.

The idea of the project

The purpose of Dscuss is quite similar to the Internet forums, but there is one fundamental difference -- social equality of all members involved (i.e no owners, no moderators, etc).

This leads to the following key features, which will be provided by Dscuss:

  • Decentralization. All the information will be stored on the users' machines.
  • Personal censorship. Every user will be able to manage her own copy of data and may share her management operations (edit message, remove message, ban user and so on) with others, who would like to accept them.

Besides that, Dscuss is designed to provide the following features:

  • Data authenticity
  • Data integrity
  • Data availability
  • SPAM resistance
  • Flood resistance

Dscuss is not intended to provide anonymity. However, this can probably be achieved using anonymizers like Tor


Dscuss is written in Go and currently has the following dependencies:

Initially Dscuss was supposed to be built on top of the GNUnet framework, but later it was considered not suitable for the purposes of Dscuss.

How to get the source code

The source code is available under GPL3. To fetch the latest source code from the git repository, run the following command:

git clone git://vminko.org/dscuss

To compile the source code run make in the root of the downloaded directory.

Progress of development

What is done so far:

  • Command-line interface.
  • The crypto subsystem.
  • Basics of the storage subsystem.
  • Registration (via proof-of-work).

What is planned for the proof-of-concept version:

  • The network subsystem.
  • Bootstrapping (via list of rendezvous nodes).
  • Membership (maintaining connections with other peers).
  • Subscription to categories (by editing a text file).
  • Handshaking.
  • Publishing a message.
  • Listing a category.
  • Threading (replying to messages).
  • Operations on messages and users.
  • Database synchronization with other peers.
  • Bootstrapping (via DHT).
