This project aims to build a secure blockchain-based voting system using the Move programming language on the Aptos blockchain. Traditional electronic voting machines (EVMs) are prone to hacking and security breaches. This blockchain-based system leverages the immutable and decentralized nature of blockchain technology to ensure the integrity, transparency, and security of the voting process.

• Security: Votes are stored on the blockchain, making it nearly impossible to tamper with the results.
• Transparency: All votes are publicly auditable, ensuring accountability.
• Rewards: Voters receive reward tokens for participating in the voting process, incentivizing voter turnout.
• Decentralized: The system is trustless and decentralized, reducing the reliance on central authorities.

The VotingSystem::BlockchainVoting module is designed to handle voting on two options (Option A and Option B). Voters can submit their vote, and they will be rewarded with AptosCoin tokens.

The Voting struct stores the following data:

• option_a_votes: Number of votes for option A
• option_b_votes: Number of votes for option B
• reward: The amount of reward (in tokens) given to voters

1. create_voting:

   • Initializes a new voting instance with a reward for participants.
   • Parameters:
     • owner: The signer who creates the voting instance.
     • reward: Amount of reward tokens to be distributed to voters.

   public entry fun create_voting(owner: &signer, reward: u64)

2. submit_vote:

   • Allows a voter to submit their vote for either Option A or Option B.
   • Parameters:
     • voter: The signer submitting the vote.
     • voting_owner: The address of the voting owner.
     • option: A vote for option A (0) or option B (1).
   • Reward Distribution:
     • The voter is rewarded with AptosCoin tokens after submitting their vote.

   public entry fun submit_vote(voter: &signer, voting_owner: address, option: u8) acquires Voting

The send_message::sup module provides a simple message storage and update mechanism on the blockchain. Users can send and update messages associated with their account.

• my_msg: A string to store the message.

1. msg:

   • Sends or updates a message for the signer.
   • Parameters:
     • account: The signer's account reference.
     • msg: The message to store or update.

   public entry fun msg(account: &signer, msg: String) acquires Message

To deploy and interact with this blockchain-based voting system, you will need:

1. Aptos CLI and Aptos Account: Set up an Aptos account and environment.
2. AptosCoin (APT): Make sure you have enough APT tokens to cover transaction fees.

Deploy the VotingSystem::BlockchainVoting module on your Aptos account.

To create a new voting instance, call the create_voting function with the reward amount in tokens.

Voters can call the submit_vote function, passing in the voting option and the voting owner's address.
