BTTC Empowers Democratic Voting with New Smart Contract

Explore the innovative voting smart contract on BitTorrent Chain (BTTC), designed to enhance transparency and security in elections.

BitTorrent Inc. has unveiled a new voting smart contract on the BitTorrent Chain (BTTC), aiming to decentralize the democratic process by ensuring transparent and tamper-proof voting. The contract encompasses candidate registration, vote casting, and winner determination, according to BitTorrent Inc..

The Voting Contract: Blueprint for Digital Democracy

The Voting Contract is meticulously designed to manage the entire voting process. Key components include:

Structs and State Variables

The contract defines structures and state variables to store voting data:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;

contract Voting {
struct Voter {
string uid;
uint candidateIDVote;
}
struct Candidate {
string name;
string party;
bool doesExist;
}
uint numCandidates;
uint numVoters;
uint256 voteDeadline;
mapping(uint => Candidate) candidates;
mapping(uint => Voter) voters;
}

Events

Events are emitted at crucial points during the voting process:

event candidateRegistered(uint candidateID);
event voteRegistered(uint voterID, uint candidateID);

Functions

Setting and Getting the Vote Deadline

function setVoteDeadline(uint256 _voteDeadline) public {
    voteDeadline = _voteDeadline;
}
function getVoteDeadline() public view returns (uint256) {
    return voteDeadline;
}

Adding Candidates

function addCandidate(string calldata name, string calldata party) public {
    numCandidates++;
    candidates[numCandidates] = Candidate(name, party, true);
    emit candidateRegistered(numCandidates);
}

Casting Votes

function vote(string calldata uid, uint candidateID) public {
    require(block.timestamp <= voteDeadline, "Voting period has ended.");
    require(candidates[candidateID].doesExist, "Candidate does not exist.");
    numVoters++;
    voters[numVoters] = Voter(uid, candidateID);
    emit voteRegistered(numVoters, candidateID);
}

Getting the Winner

function getWinner() public view returns (string memory winnerName) {
    uint[] memory voteCounts = new uint[](numCandidates + 1);
    for (uint i = 1; i <= numVoters; i++) {
        voteCounts[voters[i].candidateIDVote]++;
    }
    uint winningVoteCount = 0;
    uint winningCandidateID = 0;
    for (uint i = 1; i <= numCandidates; i++) {
        if (voteCounts[i] > winningVoteCount) {
            winningVoteCount = voteCounts[i];
            winningCandidateID = i;
        }
    }
    return candidates[winningCandidateID].name;
}

Getting Total Votes for a Candidate

function totalVotes(uint candidateID) public view returns (uint) {
    uint voteCount = 0;
    for (uint i = 1; i <= numVoters; i++) {
        if (voters[i].candidateIDVote == candidateID) {
            voteCount++;
        }
    }
    return voteCount;
}

The Power of Decentralized Voting

This Voting Contract illustrates how blockchain technology can transform traditional voting systems by enhancing transparency, immutability, and security.

Beyond the Basics: Enhancing Your Voting Contract

Consider adding the following features to enhance the basic voting contract:

• Implement voter registration to prevent duplicate voting.
• Add candidate verification mechanisms.
• Create a user-friendly frontend for voter interaction.

Conclusion: Shaping the Future of Democracy

This Voting Contract is a significant step towards decentralizing democracy, ensuring every vote counts and every election is transparent and fair. The blockchain world offers endless possibilities, and the future of democracy is in your hands.
