Block Chain voting system

Deployment:

When deploying the votingSystem smart contract, you need to ensure that the deployment is done from an account that you trust with ownership privileges. This account will become the contractOwner and will have special permissions to manage the voting process.

Registration

1. Registering Candidates:
   • Use the registerCandidates function to add candidates to the candidateList.
   • Only the contractOwner can register candidates, ensuring that the process is controlled and managed by the owner.

Voting

1.Casting Votes:

• Voters can cast their votes using the addVote function.
• The onlyOnce modifier ensures that each voter can cast only one vote.
• The function checks if the candidate is valid and if the voter has not already cast a vote.

Management

1. Starting the Voting Process :

• The contractOwner can start the voting process using the startVoting function.
• This action changes the status of the voting process to running, allowing voters to cast their votes.

2. Stopping the Voting Process :

• The contractOwner can stop the voting process using the stopVoting function.
• This action changes the status of the voting process to completed, indicating that the voting process has ended.

Result

1. Determining the Winner :

• After the voting process is completed, the contractOwner can determine the winner using the getWinner function.
• The function calculates the candidate with the highest number of votes and returns their address along with the total number of votes they received.

Best Practices

• Security : Ensure that the contractOwner account is secure and not vulnerable to unauthorized access.
