libbrandt GSoC midterm status update


the GSoC midterm evaluation finished this week and it's time for a status update on the libbrandt auctioning library project.

In the past few weeks we decided to switch from RSA like crypto to Ed25519 due to performance reasons and it's generally more modern approach. Therefore we don't use libpari anymore, but libgcrypt instead. Ed25519 also has no need to validate each input value from other protocol participants.

Rust implementation of GNUnet with GSoC - Mid-term progress

The GSoC mid-term evaluation is happening now, so this is a good time to write up the work I've done so far. My contributions are threefold. The files mentioned below can be found in the async branch (

Rust implementation of GNUnet with GSoC


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 -

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

libbrandt GSoC kickoff


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.

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 if you are interested to present your work or organize something practical. Topics include:
