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…

Automated testing of such APIs requires generating sequences of API calls, and when we find a failing test, ideally shrinking such a sequence to a minimal test case. Neither the generation nor the shrinking of such…

In this blog, wallet API lead Matthias Benkort explains backwards-incompatible Cardano wallet API changes that are coming in Cardano 1.4, and devOps lead Jacob Mitchell shows how to build a Cardano client with both the old V0 wallet API and the new V1 wallet API, instead of the default option providing only the new API. This blog post is mainly intended for current users of the…

Cardano, the third-generation blockchain, is evolving. Cardano changes are planned as product increments within Cardano development phases, and are implemented and released as Cardano software. In this blog, product manager Darko Mijic, release manager Tatyana Valkevych and devOps lead Jacob Mitchell clarify how Cardano is versioned as a blockchain product and as software, and…
