Blockchain for the electronic voting system: case study: student representative vote in Tunisian institute

Votingis a basic element of running a country. Voting will continue to take place by physically entering the voting booth. No security is guaranteed for this operation, and several cases of tampering have been noted. In order to eliminate this type of problem, the paper proposes an online voting process with blockchain technology. With encryption and hashing, the security of each vote is ensured. The votes will be stored as transactions. A peer-to-peer network is leveraged to share this distributed ledger with voting transactions. The application is designed to hide the complexities of the architecture from the user. With the QR code, each student is uniquely identified. This ensures that each voter has only one chance to vote. With the public and private key, each node will have the ability to securely encrypt, hash, and add transactions to the blockchain. Votes cannot be traced back to the voters. This paper creates a peer-to-peer network with at least three peers. This paper plans to increase voter turnout through online voting. The scalability of blockchain applications depends on the secondary storage limits of peers.
