Back from popular demand, we’re taking a step back to walkthrough and understand the Hello World example project on the Plutus Playground to create a smart contract on the Cardano blockchain.

In this video, we will be learning about some of the concepts needed to build up a Plutus smart contract by talking about:
1) Contracts
2) Schema

And we’ll also be doing a light introduction on some of the Haskell syntax that shows up in the project.

🚀 Code from the video:
