In at the deep end in Addis

I started with IOHK in May 2018 as a formal methods developer working on two components of Cardano, neither of which involved writing Haskell code. Because of my expertise in logic, type theory, proof assistants, and theoretical computer science, I became part of the team without having much Haskell experience, even though it is the main language we use. So, I was surprised…

How we use Nix at IOHK

IOHK has a history of putting great research into practice. This includes the use of functional programming languages, adoption of formal methods, and — of course — implementing our own peer-reviewed research into blockchain consensus algorithms. We approach the problem of software deployment in similar vein, using ideas which have emerged from recent academic work. This system…
