Voting Sessions

Upon the creation of a proposal, where the administrator defines the title, description, and the start and end of each period, a voting session is created. A voting session is divided into three non-overlapping periods:

1. Choice Registration Period: The administrator can add choices to a proposal.
2. Voter Registration Period: The administrator can register voters to participate in the proposal.
3. Voting Period: Registered voters can cast their votes.

Features

• Create Proposal: Administrator can create proposals with a title, description, and defined time periods for choice registration, voter registration, and voting.
• Add Choices: Administrator can add choices to an existing proposal during the choice registration period.
• Register Voters: Administrator can register a voter to participate in a proposal during the voter registration period.
• Cast Vote: Registered voters can cast their votes during the voting period.

3. Register Voters register_voter:
