In this post, we introduce Marlowe, a new language for financial contracts, and describe the benefits of it being a domain-specific language (DSL). As a DSL it describes only financial contracts, rather than smart contracts in general. Because of this, it differs from general-purpose blockchain languages like Solidity and Bitcoin Script.

Marlowe is industry-scale. We have built Marlowe contracts based on examples from one of the leading projects for financial smart contracts, the Algorithmic Contract Types Unified Standards (Actus) system. Currently, these and other examples can be seen in the Marlowe Playground…

Creating a decentralized financial and social operating system for the world is the core mission of Cardano. But it’s not one that we can accomplish alone. That’s why we are always on the lookout for relationships which help us build a global foundation for growth. So, we’re thrilled to announce our hackathon challenge to support the UN’s sustainable development goals (SDGs…

In our Developer Deep Dive series of occasional technical blogs, we invite IOHK’s engineers to discuss their latest work and insights.

Haskell is a lazy language. The importance of laziness has been widely discussed elsewhere: Why Functional Programming Matters is one of the classic papers on the topic, and A History of Haskell: Being Lazy with Class discusses it at length as…

Today, we are announcing the launch of Project Catalyst’s first public fund, an important first step into the world of on-chain governance, treasury, and community innovation for Cardano.

The public fund launch follows five months of intense activity, across two previous trial ‘funds’. ‘Fund 0’ was the very first experiment, using a focus group made up from IOG team members…

Designing a groundbreaking proof-of-stake blockchain means it is vital to ensure that the system is self-sustainable. This will allow it to drive growth and maturity in a truly decentralized and organic way. Voltaire is IOHK’s way of establishing this capability, allowing the community to maintain the Cardano blockchain while continuing to develop it by proposing and…
