Marlowe
Get started with Marlowe#
Marlowe is the domain-specific language (DSL) that allows users to build blockchain applications tailored to financial contracts.
Take a look at the Marlowe Tutorial if you want to learn Marlowe from the beginning or dive straight into the Marlowe Playground:
Talk to others about Marlowe on the Cardano Forum or if you prefer Telegram there is a dedicated Marlowe Telegram Group.
The Marlowe platform#
With the Marlowe DSL you gain huge efficiencies because you can get much better security, much better certainty, much better guarantees of termination, and correctness of behavior compared to a Turing-complete language.
The design guarantees the following:
- Contracts are finite. No recursion or loops.
- Contracts will terminate. Timeout on all actions.
- Contracts have a defined lifetime.
- No assets retained on close.
- Conservation of value.
Marlowe Playground#
The Marlowe Playground is an easy-to-use, visual, and modular plug-and-play smart contract builder and simulator. Watch this 4 minute long tour of the Marlowe Playground: build, simulate and analyse Marlowe contracts.
