This workshop is centered around a Move contract, designed to facilitate a voting system on the Sui blockchain. Accompanying the contract is a script enabling the execution of on-chain methods.

The contract serves as a foundation to explore various key concepts of blockchain development within the Sui ecosystem, such as object ownership, Table data structures, error handling, and NFT (Non-Fungible Token) lifecycle, including creation and display mechanisms. The workshop is crafted to provide a educational experience, bridging the gap between theoretical knowledge and practical application in blockchain technology.

Through this workshop, participants will gain hands-on experience with the Sui blockchain's unique features, empowering them with the skills to build decentralized applications (dApps).

• Prerequisites
• Usage
• Methods

Ensure you have the following installed:

• Sui CLI: The command-line interface for interacting with the Sui blockchain. Installation instructions can be found in the Sui documentation.

• Node.js: The runtime environment for executing JavaScript code server-side. You can download and install it from the official Node.js website. (IF YOU PLAN ON USING THE SCRIPT)

• Git: Version control system to clone the repository. Install from git-scm.com if it's not already available on your system.

1. Clone the Repository: Obtain a copy of the source code on your local machine.

   git clone https://github.com/4-point-0/sui_workshop.git

2. Publish the Smart Contract: Publish the package.

   sui client publish --gas-budget <BUDGET_VALUE> --skip-dependency-verification

3. Use Node script OR CLI to invoke methods: Use the Node script or CLI to invoke the on-chain methods

   CLI usage:

   sui client call --package <PACKAGE> --module <MODULE> --function <FUNCTION_NAME> --args <ARGUMENTS> --gas-budget <BUDGET>

   Node script usage:

   GO AND CHANGE THE VALUES (addresses, packages etc.) IN METHODS BEFORE USING

   1. Go to script folder and install dependencies

   cd scripts

   npm i

   2. Call a method via the script

   GO AND CHANGE THE ADDRESSES AND MNEMONICS IN THE SCRIPT SO YOUR WALLET IS SIGNING THE MESSAGE AND YOU'RE CALING YOUR CONTRACT METHOD

   node script.js <METHOD_NAME>

The Sui Voting System contract provides a set of callable methods to interact with the polling system on the Sui blockchain. Below are the primary methods and their descriptions:

• Description: This method allows a user to create a new poll with a specified question and a list of options.
• Parameters:
  • question: A String representing the poll's question.
  • options: A vector<String> representing the different choices available in the poll.

• Description: Cast a vote in an active poll and receive an "I voted" NFT as a reward.

• Parameters:

  • poll: A reference to the active Poll object.
  • option: A u64 index of the selected option from the poll.
  • name: A String representing the voter's identity. (would be an wallet address, but for workshop simplicity we left this as a name string)

• Description: Change the active status of a poll to either open or close it to further voting.

• Parameters:

  • poll: A mutable reference to the Poll object.
  • status: A bool flag representing the desired status (true for open, false for closed).

• Description: Retrieve the current tally of votes for each option in a poll. (only for devInspect or dryRun through script)

• Parameters:

  • poll: A mutable reference to the Poll object.
