Marlowe: industry-scale financial smart contracts for the blockchain
Move over Solidity – this specialized language will bring decentralized finance to Cardano
6 October 2020 5 mins read
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…
Developer challenge: using blockchain to support the UN’s sustainable development goals
IOHK has set up a $10,000 fund to invest in ideas for sustainable development based on Cardano.

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…
Being lazy without getting bloated
Haskell nothunks library goes a long way towards making memory leaks a thing of the past

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…
Project Catalyst; introducing our first public fund for Cardano community innovation
An exciting experiment to start building the future of Cardano
16 September 2020 4 mins read
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…
Project Catalyst and Voltaire bring power to the people
Establishing a long-term future for Cardano growth has begun with a treasury and democratic voting in the Catalyst project
10 September 2020 7 mins read
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…
