Exercises

• Week #1

  • Clone the The Plutus repository, check out the correct commit as specified in cabal.project.
  • Install NixOS cross-referencing the following resources.
    • https://nixos.org/download.html
    • https://docs.plutus-community.com
    • A few resources to understand the what and why regarding NixOS
      • https://nixos.org/manual/nix/stable
      • https://serokell.io/blog/what-is-nix
  • Set-up IOHK binary caches How to set up the IOHK binary caches. "If you do not do this, you will end up building GHC, which takes several hours. If you find yourself building GHC, STOP and fix the cache."
  • Enter a nix-shell.
  • Build the English Auction contract with cabal build (you may need to run cabal update first).
  • Go to the plutus-playground-client folder.
  • Start the Playground server with plutus-playground-server.
  • Start the Playground client (in another nix-shell) with npm run start.
  • Copy-paste the auction contract into the Playground editor.
  • Compile.
  • Simulate various auction scenarios.

• Week #2

  • Fix and complete the code in the Homework1 module.
  • Fix and complete the code in the Homework2 module.

• Week #3

  • Fix and complete the code in the Homework1 module.
  • Fix and complete the code in the Homework2 module.

• Week #4

  • Implement function payTrace in the Homework module.
  • Handle exceptions thrown by submitTx in function payContract in the same module.
