E-Voting using Blockchain

Blockchain is a distributed, digitized and consensus- based secure information storage mechanism. The present article provides an overview of using blockchain to create a secure and reliable e-voting system. The primary purpose of this review is to study the up-to-date state of blockchain-based voting research along with associated possible challenges while aiming to forecast future directions. The methodology applied in this paper is a systematic review approach. Following an introduction to the basic structure and features of the blockchain in relation to e-voting, we provide a conceptual description of the desired blockchain-based e-voting application. Symmetrical and asymmetrical cryptography improvements play a key role in developing blockchain systems. We have extracted and reviewed multiple research papers from scientific databases that have advised the adoption of the blockchain framework to voting systems. These articles indicate that blockchain-supported voting systems may provide different solutions than traditional e-voting. We classified the main prevailing issues into the five following categories: general, integrity, coin based, privacy and consensus. As a result of this research, it was determined that blockchain systems can provide solutions to certain problems that prevail in current election systems. Using this application we try to architect a system that maintains the core and most important principles related to a voting system like: transparency, confidentiality, security, decentralization and also provides an added advantage of mobility.
