NOTICE: This course is out of date. It shows MARLOWE as it was in 2019. We are currently working in the new edition that depicts the latest development of the MARLOWE programming language.

Marlowe is a new language for modeling financial instruments as smart contracts on a blockchain. It has been designed for people who are business engineers or subject experts rather than experienced developers. It is a simple domain-specific language (DSL) which comprises a small number of powerful building blocks that can be assembled into expressive financial contracts. It is embedded in the Haskell language, which has its own established ecosystem and testing framework. You do not need programming expertise to use Marlowe and you can explore your Marlowe financial constructions with a browser-based contract editor and simulator.

We would like to thank the cardano forum community for their help in creating this class, in particular:

  • @alexludden for  close captioning and translations to spanish and french.

  • @carlos_lopez_de_lara for graphic design and video editing

  • @zzantares for reviewing the scripts of the examples.

Who this course is for:

  • Financial experts, business people, accountants, lawyers, entrepreneurs, programmers interested in smart contracts.
