Level 1 - What is your dream?

Introduction

"Welcome to the Motoko Academy - we are thrilled to have you here!" As you stand at the entrance, a large luminous hologram greets you.

Behind the glow of the hologram, the large hall opens up, filled with energy and innovation. You first notice the screens filled with lines of code - it's not just display, you can see live feeds of ongoing projects, showcasing the real-time development of groundbreaking applications and systems.

There are also monitors around, displaying images of innovative projects and groundbreaking technology.

On one screen, you notice a short-movie about a DAO focused on preserving biodiversity. Members from around the world collaborate to fund and manage conservation projects, using blockchain to ensure transparency and equitable participation.

On another screen, you can see a city, but it looks different than what you might expect. The buildings have plants growing all over them, bringing a splash of green to the usual gray of the city. You can see people walking around, but they are not in cars. Instead, they are using different types of electric vehicles, from bikes to scooters to skateboards. You learn that the city is self-sufficient, producing its own food and energy. Also, the city is run by a DAO, where all the citizens are members.

In one corner of the room, there’s a huge fish tank. But this fish tank is a bit different. You noyice little robots swimming around with the fish. The robots are there to check if the water is clean and to help take care of the plants. It's like gardeners but for the underwater world.

This hall isn't just a typical classroom. It’s clear that this is a place of growth, discovery, and connection to something greater than oneself.

While you're lost in your thought, the artifical voice from the hologram gently asks: "What is your dream?"

This is about turning your dreams into reality. That why before you dive into Motoko and coding, it's time to grow and develop your vision.

🎯 Mission

Your task, should you decide to embark on this journey, is to lay down the foundation and set the direction for your DAO. Here at Motoko Academy, we believe that a strong foundation is key to creating a successful DAO, and it all starts with a clear and well-defined dream.
So, take this moment to reflect:

  • How do you want to live your life?
  • What’s your idea (doesn't matter if it's small or big)?
  • What do you want to achieve?
  • What's your vision for the future?

Your DAO will be the vessel to help you achieve your dreams.

Task 1: Define a name for you DAO

Implement an immutable variable name of type Text that represents the name of your DAO.

Task 2: Define a manifesto for you DAO

Implement a mutable variable manifesto of type Text that represents the manifesto of your DAO.

A manifesto is a public declaration of the intentions, motives, or views of an individual or group. It is often political in nature, but may present an individual's life stance. Source - Wikipedia

Task 3: Implement the getName query function

The getName function should:

  • Takes no parameters
  • Return the name of your DAO
getName : shared query () -> async Text;

Task 4: Implement the getManifesto query function

The getManifesto function should:

  • Takes no parameters
  • Return the manifesto of your DAO
getManifesto : shared query () -> async Text;

Task 5: Implement the setManifesto update function

The setManifesto function should:

  • Take a manifesto as a parameter of type Text
  • Set the manifesto variable to the value of the parameter
  • Return nothing
setManifesto : shared (manifesto : Text) -> async ();

Task 6: Define a list of goals for your DAO

Implement a mutable variable goals of type Buffer<Text> that represents the goals of your DAO.

Task 7: Implement the addGoal function

The addGoal function should:

  • Take a goal as a parameter of type Text
  • Add a new goal to the goals buffer
  • Return nothing
addGoal : shared (goal : Text) -> async ();

Task 8: Implement the getGoals query function

The getGoals function should:

  • Take no parameters
  • Return all the goals of your DAO in an Array
getGoals : shared query () -> async [Text];

📺 Interface

At the end of this level, your canister should implement the following interface:

actor {
    getName : shared query () -> async Text;
    getManifesto : shared query () -> async Text;
    setManifesto : shared (manifesto : Text) -> async ();
    addGoal : shared (goal : Text) -> async ();
    getGoals : shared query () -> async [Text];
}
