ink presentation

Frank:

1. Short recap of a pallet -> pallet contracts -> ink!
2. Why ink! (why rust)

Andrew:
3. Demo 1, showing:

• new
  • contract structure (going through the macros):
    • storage
    • contructor
    • message
    • event
    • ?environment? (which information (e.g. caller, balance of caller) is available by default, we could leave this for the next group since they will handle custom environments)
    • ?traits?
• check
• build (what is special about cargo contract build compared to cargo build?)
  • .contract:
    • .wasm
    • .json (explain metadata)
• test
  • e2e-test (explaining / showing e2e-tests with a node running)
• upload
• instantiate
  • Explaining the difference between uploading and instantiating
• call (showing how to call a contract)
• decode (?)

Daan:
4. Demo 2,

• delegator
  • instantiate all together (original delegator example)
  • instantiate delegator with already instantiated instances of other contracts (includes selectors)
• upgrade a contract

---

Leaves for the next group:

• storage
• traits (how big is this topic?)
• chain extensions
• (custom) environment
