In this blog, we will examine how a blockchain and smart contract powered decentralized e-voting framework, in comparison to the current voting system, provides efficient service to voters by offering transparency and versatility. Owing to problems such as vote tampering, vote phishing, and the infiltration of polling stations, existing voting mechanisms are faulty. By introducing voting authentication using biometric, dynamic polling loading, and validation after casting a vote with the aid of Blockchain smart contract solutions, we figure out how to solve the constraints of the current e-voting system.

Blockchain is one of the modern era’s increasing developments that ensures the overall flexibility of e-casting a ballot. We would study a blockchain system that turns the established political process mechanism into an automated security model with improved security.

Blockchain Technology

Blockchain is one of the new technologies that enable applications to accomplish resilient authentication strategies with solid cryptographic frameworks. Essentially, it is a distributed database that holds a complete set of data records that are continuously increasing. It protects them from illegal alteration, modification, and update.

Users can access the network, start sending transactions to it, validate transactions, and build new blocks with Blockchain. A cryptographic hash gets allocated to each block. It remains acceptable as long as the documents are not modified. The cryptographic hash, if anyone changes information within a block, can show that it may be due to malicious activity. Blockchain has since been widely used to prevent illegal transfers across diverse environments because of its solid roots in cryptography.

Decentralized E-Voting System Developed with Blockchain

We discuss a theoretical decentralized e-voting model built with blockchain technology to administer the election in this section. We back a proposal to incorporate blockchain technology with state-of-the-art e-balloting technology. The following are the modules involved in the design.

Validation of stakeholders through Biometric

In this module, at the Voter Registration stage of the election process, voter information such as name, gender, address, and biometric is obtained, using which voters get validated before voting.

Ballot Configuration Dynamically

This module, based on the location of residence, loads voters and participants onto the ballot. Then, an elector has to pick his or her preferred participant. Thus, the elector does not need to drive to their home to exercise their right to vote in a polling booth nearby. To achieve ballot secrecy, no outside investigator can decide on which an elector voted.

Vote Validation after Voting

After making a transaction, a transaction ID gets created on the blockchain network. A transaction ID is created for each transaction when voters cast their votes on the blockchain network. It is provided to the user as an identification using which electors can validate their vote.
