Voter Whitelisting in Blockchain-based E-Voting using Merkle Tree

Blockchain-based e-voting systems use smart contracts to eliminate intermediaries, such as election officials, to automate voting. Traditional e-voting mechanisms have been demonstrated to be obscure and thus have led to declining voter confidence. This paper proposes deploying the voter application on blockchain for a decentralized environment to provide open and transparent voting. While ERC20 tokens diminish plural voting, Merkle Tree ensures scalable storage of voter data for whitelisting. The proposed solution can overcome scalability, double-spending, and plural voting challenges. The results documented in the paper prove that the proposed solution is efficient in the gas units spent and ensures faster verification than the existing solutions. Thus, the proposed blockchain e-voting mechanism ensures significant features of an ideal e-voting system
