摘要
En 中文
Voting is one of the fundamental pillars of modern democracy. Continuous efforts have been made to strengthen the processes and methods involved to achieve verifiable, transparent voting systems. In recent years, blockchain has been increasingly used to address multi-dimensional challenges across widespread application domains including healthcare, finance and e-voting. However, achieving an efficient solution via use of blockchain requires consideration of a range of factors such as block generation rate, transaction speed, and block size which have a profound role in determining the overall performance of the solution. Current research into this aspect of blockchain is focused on Bitcoin with the objective to achieve comparable performance as of existing online payment systems such as VISA. However, there exists a gap in literature with respect to investigating performance constraints for wider application domains. In this paper, we present our efforts to address this gap by presenting a detailed study into performance and scalability constraints for an e-voting system. Specifically, we conducted rigorous experimentation with permissioned and permissionless blockchain settings across different scenarios with respect to voting population, block size, block generation rate and transaction speed. The experiments highlighted interesting observations with respect to the impact of these parameters on the overall efficiency and scalability of the e-voting model including trade-offs between different parameters as well as security and performance.
