Towards Developing a Secure and Robust Solution for E-Voting using Blockchain

Blockchain is one of the upcoming technologies in computing. It provides a tamper-proof distributed ledger which ensures integrity and authentication, as well as eliminates the need of a centralized trusted authority. This results in a secure and trusted system observed by the public. Although the blockchain was first applied to cryptocurrencies (which resulted in bitcoin), the features it provides are desirable for several other applications. In this paper, we develop a blockchain-based solution for securely digitizing the voting process. Election process is an important test of democracy and rigging the election may have disastrous consequences. Through our solution, we aim to provide a platform for voters to cast their vote securely online, from their home. The votes will be published in the blockchain, which will be observable by everyone. This would result in a tamper-proof ballot system which would be impossible to manipulate. The anonymity of voters will be maintained. We aim to apply this in the Indian context. We further show how our system meets the requirement of an online voting system, and how it resolves the issues present in current as well as proposed systems for the same.
