E-Vote Decentralized

Overview

The MultiElectionVoting smart contract is designed to manage multiple elections, allowing for the registration of candidates and voters, as well as the recording of votes in a decentralized and secure manner. The contract leverages the ERC2771Context for meta-transactions, ensuring that operations are executed within the context of trusted forwarders.

• Candidate Registration: Add candidates to specific elections before the election start date.

• Voter Accreditation: Register voters for specific elections, ensuring only accredited voters can participate.

• Voting: Accredited voters can vote for registered candidates within the active election period.

• Voting History: allows voters to track their voting activities onchain.
