Did you know that #GNU/ #FSF has its own #darknet application and protocol stack?

What is #GNUnet?

GNUnet is an
#alternative #network stack for building #secure, #decentralized and #privacy-preserving #distributed applications. Our goal is to replace the old insecure Internet protocol stack. Starting from an application for secure #publication of #files, it has grown to include all kinds of basic protocol components and applications towards the creation of a GNU internet.

Today, the actual use and thus the social requirements for a global network differs widely from those goals of 1970. While the Internet remains suitable for military use, where the network equipment is operated by a command hierarchy and when necessary isolated from the rest of the world, the situation is less tenable for civil society.

Due to fundamental Internet design choices, Internet traffic can be misdirected, intercepted, censored and manipulated by hostile routers on the network. And indeed, the modern Internet has evolved exactly to the point where, as Matthew Green put it, "the network is hostile".

We believe liberal societies need a
#network #architecture that uses the #anti-authoritarian #decentralized #peer-to-peer paradigm and #privacy-preserving #cryptographic #protocols. The goal of the GNUnet project is to provide a Free Software realization of this ideal.

Continued thread

But cryptography is hard. Until recently, institutions and individuals who need to run #cryptographic operations had to rely on specialists to review the code that their applications is running. Cryptography can protect our privacy and authenticate sources of important information. For #cryptography to work for the people, the people need to understand it.

The #chatmail #fosdem talk from @compl4xx is public. It goes into topics such as

- why chatmail servers?
- how to setup a server with your child
- (avoiding) spam filtering
- metadata and guaranteed end to end encryption in #deltachat
- #cryptographic #interoperability for email message routing

Thanks to attendees for the great energy even if was the last talk on the day and also for questions and conversations afterwards!
