About GNUnet

GNUnet is a mesh routing layer for end-to-end encrypted networking and a framework for distributed applications designed to replace the old insecure Internet protocol stack.

In other words, GNUnet provides a strong foundation of free software for a global, distributed network that provides security and privacy. Along with an application for secure publication of files, it has grown to include all kinds of basic applications for the foundation of a GNU internet.

GNUnet is an official GNU package. GNUnet can be downloaded from GNU and the GNU mirrors.

Rust implementation of GNUnet with GSoC

Hello,

I will be participating in Google Summer of Code this year with GNUnet. The project is on improving the Rust implementation of GNUnet utils. The primary objective is to add asynchronous IO in a way that is general, extensible and resemble the original GNUnet API. More details can be found here - https://summerofcode.withgoogle.com/projects/#6454361462931456

Jeff Burdges is my mentor and I will be working closely with him on this project.

All the code I produce will be on my own fork of gnunet-rs (on the gsoc branch) which can be found here - https://github.com/kc1212/gnunet-rs

libbrandt GSoC kickoff

Heyho,

I was accepted for a Google Summer of Code project and will be developing an auctioning library. During the community bonding period I have so far read four papers relevant to the topic, choosen a few algorithms with slightly different properties which I want to implement and reconstructed one of them within the pari/gp CLI (see attachment). I also started with a first draft of the library interface which will be published in a git repository shortly.

I also made some decisions with my mentor, Christian Grothoff regarding implementation details and project goals:

  • The library will be called libbrandt in honor of Felix Brandt who developed the algorithms that will be used.
  • We want to support first price and (M+1)st price auctions.
  • The outcome of the auction can either be private (only revealed to the seller and winners) or public, choosen by the seller at auction creation time.
  • Selling multiple instances of the same item to the same agent will not be supported as the buyer can just place an arbitrary amount of bids by creating sibling agents.
  • Tie breaking is planned to favor the agent who registered first for an auction giving a motivation to potential buyers to sign up early.
  • Currency and actual price mapping is left to the library user.

GNUnet e.V. Assembly 2015

The annual GNUnet e.V. assembly is upon us. We'll meet on December 29th at 20:30 in Hall F at 32c3 in Hamburg. Below is the agenda.

  • Financial report (Florian Dold)
  • Election of the Vorstand
  • Discussion of the proposal from the p≡p Foundation

The p≡p foundation would like us to enter into an agreement. Their initial draft proposal (nothing final) is below (in DE and EN). Matthias and Christian can give some background on their motivations at the meeting. The goal of the discussion will be to get some feedback from the members and a mandate for the Vorstand in terms of the direction for how to proceed.

German Edition

GnuNet e.V. und p≡p foundation beschliessen eine
Entwicklungspartnerschaft.

  1. Sowohl GnuNet e.V. als auch p≡p foundation wollen zukünftig die
    Software GnuNet weiter entwickeln. Dazu beschliessen die beiden
    Parteien, dass hiermit p≡p foundation ebenfalls Eigentum an der
    Software GnuNet haben wird. GnuNet e.V. gibt dabei sein Eigentum
    nicht auf, sondern zukünftig werden beide Entitäten jeweils im
    urheberrechtlichen Sinne volles Eigentum an jeweils einer Kopie der
    Software GnuNet halten. Dazu überträgt GnuNet e.V. das Eigentum an
    einer Kopie der Software GnuNet an p≡p foundation.
  2. p≡p foundation garantiert, dass sie die Software GnuNet und alle
    Ableitungen und Weiterentwicklungen davon unter der Gnu General
    Public License 3.0 veröffentlichen wird.
  3. GnuNet e.V. und p≡p foundation vereinbaren jetzt bereits, dass das
    Eigentum an allen Weiterentwicklungen der Software GnuNet wiederum in
    Kopie an die jeweilige andere Partei übertragen wird. Dabei gilt
    diese Übertragung jeweils als vollzogen, sobald eine der beiden
    Parteien eine Weiterentwicklung der Software veröffentlicht.
  4. GnuNet e.V. und p≡p foundation planen, die beiden Kopien konsistent
    zu halten (kein sogenannter “Fork”). Dazu vereinbaren die beiden
    Parteien eine Zusammenarbeit in der Softwareentwicklung, sowie
    Zusammenarbeit in Forschungsfragen zum Themenbereich sichere und
    private verteilte Systeme. Näheres regeln Einzelvereinbarungen zu
    diesen Themen.

English edition

GnuNet e.V. and p≡p foundation are agreeing on a development
partnership.

  1. Both GnuNet e.V. and p≡p foundation are aiming to develop the
    software program GnuNet together. Therefore, the two parties agree on
    p≡p foundation gaining ownership on the software program GnuNet, too.
    GnuNet e.V. does not give up its ownership, though. Instead, in the
    future both entities will have a mirrored ownership on a copy of the
    software program GnuNet, respectively. Hence GnuNet e.V. is
    transferring full ownership of a copy of the software program GnuNet
    to p≡p foundation.
  2. p≡p foundation is assuring to publish the software program GnuNet and
    all deductions and further development of it unter Gnu General Public
    License 3.0.
  3. GnuNet e.V. and p≡p foundation have agreed already, that the legal
    property of all future deductions of the software program GnuNet will
    be transferred to the other party, respectively. Such transfer will
    be completed by publishing a derivation.
  4. GnuNet e.V. and p≡p foundation are aiming to keep the two copies
    consistent (no “fork”). Therefore, the two parties are agreeing on
    further common development as well as further cooperation in research
    on privacy and security with distributed systems. Details on these
    further working together will be elaborated in individual
    arrangement, respectively.

YBTI @ 32c3

The "YBTI/We Fix the Net" assembly" is to be the perfect place at 32c3 for all hackers to do something about replacing today's broken Internet with secure alternatives. We hope to have some talks and panels like in previous years. Details will be posted here closer to the congress, for now, please contact us at wefixthenet@gnunet.org if you are interested to present your work or organize something practical. Topics include:

  • solutions against the deep state
  • mass surveilance and doing something against it
  • ethical computer security research

Even if we in the end cannot assign you a slot, please feel free to join us for a chat, for a coding session, or general exchange of ideas.

Schedule

We are posing the schedule in the 32c3 wiki at
https://events.ccc.de/congress/2015/wiki/Session:YBTI. Basically, we'll be most of December 29th in Hall F. If you are interested in participating, please contact us, we have room in the schedule for more!

Video: Reproducible Software Deployment with GNU Guix

Ludovic Courtès presented his vision for future secure operating system distributions using GNU Guix today, including a surprising number of GNUnet references.

Abstract

“It used to work perfectly, then I upgraded something, and somehow...”. Sounds like a déjà vu? Sometimes feel like software deployment is unpredictable? You think reproducible research demands reproducible software deployment? Ever wondered if you can trust your compiler or the integrity of those binary packages you have downloaded?

This talk introduces GNU Guix, a package manager that implements the functional package management paradigm pioneered by Nix to address these issues. Guix supports transactional upgrades and rollbacks, as well as support for multiple software profiles. In this talk, I will introduce functional package management and demonstrate Guix on practical use cases. I will discuss the implications on (bit-)reproducible packages and environments, and how this can lead to verifiable binaries. Lastly, we will see how this extends to whole-system deployments with GuixSD, the Guix System Distribution.

About the Speaker

Ludovic is a research engineer in the Development and experimentation department at Inria Bordeaux Sud-Ouest. Aside from his duties at Inria, he is co-maintainer of GNU Guile, an implementation of the Scheme functional programming language, and the maintainer of GNU Guix.
