IOHK has been building our flagship decentralized infrastructure product Cardano for over two years now, which is one of the most robust proof of stake blockchain protocols in the world.

The Cardano project has now reached a stage of maturity where parties interested in the technology and its potential real-world value are asking: what else can Cardano's underlying technology be used for? What are some of the problems we can solve with this technology, and in what industries can this technology be most impactful?

We’re now ready to answer these questions and we are building a world-class team to complement Cardano with an enterprise-focused product line and this time we are using Scala as the primary coding language.
