In his talk he will try to explain what the point of all that work is, and what he hopes the Nix ecosystem will gain from its adoption in the future. If there is interest, he can also talk a bit about his other project vibenix, which autonomously creates Nix packages starting from a repository URL. Both projects are part of Martin’s research on supply chain security at JKU in Linz, where he is working on his PhD. ...
