Actus smart contracts in Marlowe

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

Marlowe is a domain-specific language for secure financial smart contracts that is being developed by IOHK for the Goguen capabilities of the Cardano blockchain. Following my introductory post on Marlowe, in this Deep Dive post…

Marlowe: industry-scale financial smart contracts for the blockchain

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

Marlowe: financial contracts on blockchain

The first computers were programmed in “machine code”. Each kind of system had a different code, and these codes were low-level and inexpressive: programs were long sequences of very simple instructions, incompressible to anyone who had not written them. Nowadays we are able to use higher-level languages like C, Java and Haskell to program systems. The same languages can be…
