I am David Stainton and I'm from San Francisco, California. I am a network security and forensics specialist, a cryptography engineer, a cryptographic protocol engineer and a mixnet designer. That is to say, I design anonymous communication networks and anonymous protocols. I am one of the original designers and founding developers of the Katzenpost mix network. In my free time away from the keyboard I lift weights, go hiking and cook healthy food.

In the past couple of years I've upgraded all of the Katzenpost cryptography to use hybrid post quantum constructions. Recently, I've extracted all the cryptography components into a newly established library named hpqc, an acronym for hybrid post-quantum cryptography.

Your sponsorship will go directly towards continued development and maintenance of Katzenpost free libre open source software project. This will allow me to fix bugs, implement new features and create new integrations.

All that having been said there are a few exciting new projects for Katzenpost!

• Firstly, we're going to be self-publishing educational material to explain what online anonymity really means.
• mixnet encrypted group chat protocol
• mixnet encrypted group chat protocol with additional PIR protections
• client library: new low level client which allows many mixnet applications to run on a single device and appear on the network as a single mixnet client; daemon/thin client architecture gives better security with privilege separation.
• code review/fixing: Would be great to get paid to code review and fix all of the contributions that have been made
