Government ministers, industry professionals, and Cardano fans were at the IOHK Summit 2019 in Miami this month, excited to hear IOHK CEO Charles Hoskinson outline the future for Cardano and launch Atala, the company’s enterprise offering for business. Hosted at the Miami Beach Convention Center, the summit saw renowned speakers such as computer scientist Stephen Wolfram and…

The goal of the Cardano Shelley era is to bring full decentralization to Cardano, moving beyond the federated epoch and handing control of the ledger over to the community via stake pools.  As part of the process of delivering Shelley, we create formal specifications which allow us to verify that the final code is in line with what the researchers initially envisaged in their…

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…

When I got off the plane at Bole airport in Addis Ababa on the evening of January 4, I did not know what to expect. It was my first time in Ethiopia, and all I knew was that my Canadian colleague Dr Polina Vinogradova, an IOHK formal methods expert, and I were supposed to teach a three-month-long Haskell course to a class of young Ethiopian and Ugandan women. When our students…

The release of Cardano 1.5 marks the start of the shift from the Cardano Byron era to the Shelley era and is an excellent opportunity to describe the ongoing work for Shelley and how the transition will happen. Roughly six months ago, we switched almost all our development efforts to the Shelley code base, and work has been progressing quickly ever since. The last major work in…
